Germination is the first step in your cannabis grow. Learn how to germinate cannabis seeds properly, by following the guides in this section of the forum. These guides on germinating cannabis seeds, will increase your chances of a successful germination. If you need any help or advice with germinating cannabis seeds, ask for help in here.
Vegetation is when a cannabis plant grows stems, branches, and leaves, but no buds or flowers. Usually, during vegetation, a cannabis plant will be topped and trained, before being "flipped" to flower. With good training, and growing techniques during vegetation, you can increase the final yield of your grow massively. Learn how to get the best out of your cannabis plant in veg, in this section of the forum.
Flowering, is when a cannabis plant grow its buds, that are also known as flowers.

- Some of the simplest but best information ya can get for a new starter or someone gettin back to it 👍2 weeks ago
- Yeah, meant to comment on this last night but ya know, weed. This is very good advice. Even here in Canada with legalization, we are still seeing/hearing about people having their gardens robbed, houses broken into, dogs threatened, etc. Best to just avoid all of this and keep it to yourself. Loose lips sink ships, as they say...2 weeks ago

- Who me? I’m not growing anything 😉 in all seriousness, the best way to stay safe by far. The part about growing more than you need is the most difficult IMO. I’d love another half dozen ladies in the dorm but we really don’t need them. Been looking at larger tents lately, maybe this is a good reminder that I don’t need to do that.2 weeks ago
- As long as you got enough to supply yourself till next harvest, its not worth going bigger IMO. 1.2 x 1.2m tent is a perfect size, with a veg tent on the side, you'll never buy weed again2 weeks ago
- New growers can often get lost in the slang and terminology. I find that a Cannabis Growers Dictionary would be very useful. Though here at Percys Grow Room, we try and make things as simple as possible for a new grower to follow, using abbreviations and slang terms can't be helped sometimes. Here is a cannabis growers dictionary of slang and terminology used by growers. This will help you understand the meaning of some of these terms. Cannabis Growers Dictionary A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z 18/6: Time normally associated with the vegetative stage of growth i.e. 18 hours of light to 6 of darkness, per day. 24/0: Lighting on constantly with no dark period. 12/12: Timing used to initiate the flowering stage of a cannabis plant indoors. For example, 12 hours light and 12 hours darkness. A A/C: (Air Conditioning) If the ambient temperatures outside of the grow room, are too high, no amount of extraction will lower the temperatures. In situations like this, you need A/C ( Air Conditioning). Active Intake: Active intake is when an extractor fan, is used to draw air into a grow room. The extractor is usually the same size, or a little smaller than the extractor fan, that draws out out if the grow room Aeration: Supplying air to water. This is usually done by using an airstone, to pump air through the water. Aeroponics: Growing of plants in a container in which the roots are suspended in a nutrient mist rather than in a solution. Air Exchange Rate: The amount if times the air in your grow room, is removed and replaced by fresh air. Usually, it will be between 20, and 30, times per hour. Air Prune: When the roots of a cannabis plant reach air, they will stop growing outwards, and the tip will stop growing. This is air pruning, and it is very helpful to over all root development. Auto: A cannabis plant that will flower under any light cycle. It will veg and flower within a set time period, and the growth cycle can not be extended. B Background EC: Background EC, or BG EC, is the electro conductivity of your source of water, before adding any nutrients. Bag Seed: A cannabis seed, found in a bag of bud. These seeds are usually produce by a female plant that has either hermaphrodited, or was pollinated by a male. Ballast: Provides current and power to the light for HID bulbs. Can be digital, or magnetic. BG EC: Background Electro Conductivity, the EC of your water before adding any nutrients. Bioavailability: The amount of THC or CBD that is actually absorbed into the blood steam, and has an effect on the user. Bloom Food: Cannabis plant nutrients designed for growth during the flowering phase. Usually lower in Nitrogen, and higher in potassium and phosphorus, than grow foods. Bud Rot: When mould spores have germinated inside of your cannabis buds. Bud rot will ruin your harvest, and you must always be vigilant in the later stages of flowering. Buds: The flowers of a female cannabis plant. They contain high concentrations of THC and other cannabinoids. C Calibration: EC and pH meters will have to be regularly calibrated to ensure their accuracy. Calyxes: The first part of the flower that is formed when a young plant enters its flowering stage. Cannabinoids: Chemical compounds that naturally occur in the resin of the cannabis plant. Canopy: The top level of a plant, where the light has most contact with the leaves. Carbon Filter: A tube filled with coal pellets, that will remove organic molecules from the air. This reduce the smell of you cannabis plants, and is vital to security.

CFL: Compact Fluorescent Lamp, grow light. CFM: Cubic Feet per Minute. This describes the volume of air that is displaced in 1 minute in your grow room. Chlorophyll: The green pigment in leaves. Chlorophyll captures the suns energy which is used to manufacture sugar from carbon dioxide and water. Cloning: The process of replicating female plants, by cutting off branches and rerooting them. COB: Chips On Board, a type of LED lighting. Colas: The main female flowers on a cannabis plant. They are bigger and longer than buds on side branches. Cooling Hoods/ Tubes: A kind of lighting fitting for HID lighting, that hold the bulb inside of a tube or hood. The air is pulled through this tube, and reduces the amount of heat put into the grow room. Cotyledons: The small round leaves that are the first to appear on a cannabis seedling. Curing: Placing the dried harvest in airtight jars and storing in a dry, dark, cool place. The jars are opened daily to release built up moisture, so the buds are dried slowly. Cuttings: Parts of a cannabis plant that have been removed for the purpose of cloning. See Also - Cloning D Decarboxylation: Wet THC dries and loses a CO2 molecule, which then makes the THC psychoactive. Deficiencies: Plant problems related to the lack of nutrients available in the medium. Dissolved Salts: This is the amount of salt based nutrients, that are dissolved into your water. DWC: Deep water culture, a very popular way of growing cannabis hydroponically, where roots are submerged in reservoirs of water. E EC: Electrical Conductivity, the conductivity of water will increase with the amount of salts added. EC is the measurement how many salts are in your water EC Spike: This is when water has been drank, or evaporated, faster than the plant can eat. The EC of the medium will rise quickly, as dissolved salts are left behind. Extraction: Equipment used to pull air out of the grow room. Usually,an RVK Extractor fan. Extracts: Products made from cannabis flowers, where resins and oils are extracted out of the buds. Shatter, Rosin, and THC Oils, are all extracts F Fan leaves: The large leaves that grow off branches. These leaves have a bigger surface area, to catch more light. Feminized Seeds: Seeds which have been bred to ensure a high chances of a female plant.

- A cannabis plant will grow differently, according to how much light it gets (daytime) compared to how much darkness it gets (nighttime). There are many different light cycles for growing cannabis indoors, each have their own pros and cons. In this post, we will discuss different light cycles for growing cannabis, when to use them, and why. This will help you understand how to grow cannabis a little more. If you have any questions about cannabis plant light cycles, that aren't covered here, feel free to ask for help in our cannabis growers forum Contents What are light cyclesCannabis Light Cycles OutdoorsSpring EquinoxSummer SolsticeAutumn/ Fall EquinoxWinter SolsticeGrowing Around the EquatorLight Cycles For Growing IndoorsTimers for Cannabis Grow Lights24/0 Light on all day20/4 Light on for 20 hours18/6 Light on for 18 hours14/10 Light on for 14 hours12/12 An Equal Amount of Day and Night10/14 Light on for 10 hours a dayPhotoperiod Cannabis PlantsNight Cycle During FlowerAutoflowering Cannabis Plants What are Light Cycles Light cycles are the amount of light, vs the amount of darkness a plant receives. A cannabis plant will start to grow in the Spring, flower throughout Summer, and be harvested in the Autumn. Throughout the year, it will receive a different amount of light, depending on what season it is. When you use light cycles indoors, you're trying to imitate the length of the day for spring time, or summer time. This will keep a plant in "veg" (simulating Springtime growth) or in "flower" (simulating Summer growth). To understand light cycles for growing cannabis, you should understand how a plant grows in its natural habitat, outdoors. Cannabis Light Cycles Outdoors As the year goes from Spring, into Summer, and then to Autumn, the days get longer, and then shorter (unless growing near the Equator). Plants can detect the changes in the amount of light they recieve, and this tells them what season they are in. Spring Equinox Sometime around March 20th, in the Northern Hemisphere, or September 23rd in the Southern Hemisphere, the days begin to get longer, and we head into spring. This is when a cannabis seed will germinate, and begin its life cycle outdoors. As the days get longer, the plant will grow more and more, and continue into its vegetative state, until the days start to become shorter. This happens shortly after the summer solstice. Summer Solstice The Summer Solstice is when the days reach their longest. Up until now, the plant has grown in its vegetative state. This is midsummer, and the plants will soon prepare themselves for flowering. It will depend on what strain you're growing, but the flowers will start to grow when the plants get around 14 hours of daylight, and ten hours of darkness. When the flowering stage begins, it will continue for around 8 to 14 weeks, until it is harvested in late Autumn Autumn/ Fall Equinox Autumn Equinox will arrive in mid September. The days are 12 hours long, and the night is also 12 hours long. This is when a cannabis plant will be in the flowering stage. By now, the plant should already be showing small flowers. When a plant starts to grow its flowers is strain dependant, and so is its harvest time. Sativa dominant strains will flower for longer than indica dominant strains, and may need to be harvested later. A cannabis plant will flower for anything from 8 to 16 weeks. But when growing outdoors, you must harvest the plant before frost sets in, and the colder weather of Winter starts. Winter Solstice At this point, your plant should already have been harvested. This is the height of Winter, when the nights are longer than the days. In its natural habitat, a cannabis plant can not survive these conditions, and would have died already. Any seeds made by the female plant, will be laying under the surface of the ground, waiting for conditions to improve. When Springtime comes again, and the climate starts to get warmer, the seeds will germinate around the Spring Equinox, and the whole cycle begins again. This is how a cannabis plant uses light cycles naturally in the wild. When you grow cannabis indoors, you have to simulate the length of the day and night, to induce certain stages of the cannabis plants life cycle. Growing around the Equator The days and nights around the Equator are always around the same length, 12 hours day, and 12 hours night. A cannabis plant can grow fine under 12/12, but it will not stay in its vegetative stage for long. About 4 weeks after germination, a cannabis plant will reach maturity, and it will be ready to grow flowers. Before this, the plant is not ready to grow buds, and even if it is on 12/12, it will only veg. You can grow cannabis using 12 hours of light, and 12 hours of darkness from seed, just like a plant grown at the Equator. But this will not speed the grow up! You still have to wait about 4 or 5 weeks after germination before the flowering cycle begins. Light Cycles For Growing Indoors The idea of using light cycles to grow cannabis indoors, is pretty much trying to simulate the sun, at certain times of the year. This is not only done with the length of day and night, but also what colour (spectrum) light the plants get. In Springtime, the light will be slightly more into the blue spectrum, and during Summer, it will be a lot more red. Different bulbs can be used at different stages of growth to imitate this. You have more control over lighting when growing cannabis indoors, and can control the length of day and night by using a timer. Timers for Cannabis Grow Lights Grow lights are heavy duty, and they use a lot of power. Because of this, you need to be sure you use the correct timer for your lighting rig. You have to be safe with your equipment, if you use a timer that isn't designed for a heavy load, it may short circuit and set fire to something. At the very least, the timer could break, and the light cycle your plants are used to will be suddenly changed, and this will cause them stress. If your plant is in flower, and there is an irregular light cycle, it can cause it to "hermie". You must use reliable, safe equipment. You can't put a price on piece of mind. 24/0: Lights on all day A cannabis plant can be grown under 24 hours of light with no dark period. This light cycle tends to be used on seedlings or cuttings in the early stages of growth. Some growers will grow autoflowering cannabis plants under 24 hours of light. But of course when growing indoors, more hours of light means more energy bills. It is not clear whether the extra energy turns into extra yield. 20/4: Lights on for 20 hours A light cycle of 20 hours light, and 4 hours darkness, tends to be used for seedlings and cuttings, or auto flowering plants. This is prefered over 24 hours of light, as it gives the plant some time to rest, and it reduces the energy bills a little. When you are growing indoors, you are trying to imitate a natural environment. All plants will receive some hours of darkness, so 20/4 is usually the most amount of light a grower will give to a plant. 18/6: Lights on for 18 hours 18/6 is the most common light cycle for growing cannabis. It used to vegetate photoperiod cannabis plants, or grow autoflowering plants for their whole life cycle. By keeping a photoperiod cannabis plant under 18 hours of light and 6 hours of darkness, it will stay in the vegetative stage. A plant can be kept in this state for years, and this is how mother plants are kept. A cannabis plant will not start to flower until it receives at least 10 hours of darkness, and 14 hours of light, but this is strain dependant. 14/10: Lights on for 14 Hours Some strains of cannabis may begin to flower with 14 hours of light, and ten hours of darkness. This is risky though, if the cannabis plant gets confused about its light cycle during the flowering period, it can "reveg" or "hermie". To ensure a plant goes into flower, and has no side effects, most cannabis plants will be flowered under 12/12. 12/12: An Equal Amount of Light and Dark 12/12 is the light cycle used to induce flowering in a cannabis plant. When the days and nights are the same length of time, a cannabis plant will release a hormone that triggers the flowering process. This hormone takes a few days to a week to build up, and then you will see flowers starting to form. The night cycle must be undisturbed, with no light interrupting it at all! Make sure that any equipment with lights on, or any light leaks coming into the grow room are sealed. Disturbing the night cycle can force the plant to re veg or hermaphrodite and grow seeds. 10/14: Lights on for 10 Hours a Day On some rare occasions, growers may opt for 10 hours of light, and 14 hours of darkness. Light degrades THC so reducing the amount of light a plant receives during the flowering stage, will reduce the amount of degradation of the THC. 10/14 can give the plant extra time to ripen towards the end of the grow, without pushing the trichomes too far. It may improve flavour and potency, but less light means less yield, so it's a cost you have to weigh up for yourself. The most popular light cycles for growing cannabis are 18/6 for veg, and 12/12 for flower. Just sticking with these two light cycles will be fine. But you can experiment if you want to, it's your grow. Photoperiod Cannabis Plants Photoperiod cannabis plants are plants that react to light cycles. For example, plants that will vegetate under 18/6 but not flower until they are under 12/12. A photoperiod cannabis plant will not reach maturity until it is around 4-5 weeks from seed. Even if a plant is grown under 12/12 from seed, flowers will not start to show until it is mature. It is always best to veg a photoperiod cannabis plant under 18/6 for at least four weeks before flipping to flower. You can veg a photoperiod cannabis plant for as long as you need to. By growing one plant, and extending the veg period by a couple of weeks, you can achieve the same yield as ten small plants. Night Cycle During Flower When growing photoperiod cannabis plants, it is vital that the hours of darkness are undisturbed. Even a small LED light on a piece of equipment in enough to stop your plant from flowering. If you have light leaks, you risk three things: 1: Your plants will not flower when you want them to2: Your plants may revert back to the vegetative stage3: Your plants will hermaphrodite, and produce seeds Before you change your light cycle to 12/12, you should make sure your tent or grow room is fully light proof, and free from any lights on the equipment. You can do this by getting into your grow room with the lights off, and all doors and vents closed. Wait for a few minutes for your eyes to adjust to the darkness, and you will see any lights coming in. Seal up light leaks with tape, or direct intake vents to draw air from a dark place. If you have any equipment in the grow room, that does give off light, remove it, or cover the light with tape, to stop it leaking out. Autoflowering Cannabis Plants Auto flowering cannabis plants are a little different, they will flower under any light cycle, 12/12, or 24 hours of light a day. This is a great advantage, as you can grow autoflowering cannabis plants along side vegetating plants, or have many autos in the same room, at different stages of growth. Light leaks can still cause problems with autos, and you should still ensure any dark period you give you plants, is fully dark, with no light leaks, or irregular exposure to light. Most growers will grow autoflowering cannabis plants under 18/6, for their whole life cycle. Some may even push it to 20/4, but it is rare that any one grows autos under 24 hours of light once they are out of the seedling stage. Final Notes on Light cycles for Growing Cannabis Keep things simple, choose which light cycle will work best for you, and decide if you are going to grow autos, or photos. When you choose you light cycle, you should set the night time, to be over the hottest part of the day. For example, if you are growing in summer, the hottest part of the day will be around midday. Because grow lights produce a lot of heat, it is advised to run them at night, and turn them off during the day. This will make it easier to keep temperatures under control.

- Knowing how to store cannabis seeds properly, is important for most indoor growers. You may start of with just a couple of seeds, but it will soon mount into a collection, and they should be stored properly, to increase their chances of still being viable. When you buy cannabis seeds from many online seed banks, you will on most occasions be given free cannabis seeds. You may also buy more seed of your favourite strain than you need, and plan to use some of them for a future grow. If you do not store your cannabis seeds properly, they can die, and you will not be able to germinate them. In this guide we will explain how to store your cannabis seeds, so your seeds will stay viable for many years. If you any questions about long term storage of cannabis seeds, that aren't covered here, feel free to ask for help in our cannabis growers forum Contents The Best Way to Store Cannabis Seeds Containers for storing Cannabis Seeds Seed TubesZiplock BagsTemperature for Storing Cannabis SeedsStoring Seeds at Room TemperatureStoring Cannabis Seed in a FridgeCan you Freeze Cannabis SeedsHumidity Levels for Storing Cannabis SeedsThe Best Humidity for Cannabis Seed StorageDesiccants Keeping Seeds in the DarkHow Long Can Cannabis Seeds be Stored The Best Way to Store Cannabis Seeds Cannabis seeds, are small, roundish shaped seeds, that are usually brown, with a few dark tiger stripes on them. Inside that tiny seed, can be the genetics to some of the best cannabis strains in the world. Sometimes, you have more seeds than you need, and you would like to store them for a future grow. If stored correctly, cannabis seeds can last for decades, and still be viable. First off, when storing cannabis seeds, they need to be in the right sort of containers. Containers for Storing Cannabis Seeds Choosing the right containers for storing cannabis seeds is important. It is easy for seeds to become damaged, and though most seed banks send their seeds in good strong packaging, some don't. Lets say, you buy ten seeds, but only need to germinate four. Six of your seed will need to be stored safely, so you can grow them in the future. The best containers are airtight, light proof and solid. The best containers you can use, for small amounts of cannabis seeds, are seed tubes. Seed Tubes for Cannabis Seeds These 1.5ml Test Tubes are perfect for storing seeds. They are airtight, solid, and the perfect size for up to ten seeds. You can buy these in bulk, 50 -100 at a time for very cheap. Using these to store your cannabis seeds, will help keep the humidity, and temperature inside the tube at a stable level. There is also space in the tube for some cotton wool, and desiccants, which is a great way keep humidity at optimal levels. Zip Lock Bags If you are going to store your seed as part of a bigger collection, in a container with more seeds, it is fine to use zip lock bags. As long as they are airtight, they will do fine. Do not use zip lock bags that have been used for other things. You should buy new bags, that are fresh and clean. Fungal spores can kill your seeds, and they are everywhere! This is another reason why keeping temps and humidity low is important. To minimise the risk of your seeds been contaminated by mould or fungus, always use clean equipment! As long as the container is: AirtightCleanStored in the right conditions You can store cannabis seeds for years! Temperature for Storing Cannabis Seeds Cannabis seed can be stored at a variety of temperatures. They might be small, but there are resistant and hardy! Though the best temperature for storing cannabis seeds is around 5°c, cannabis seed can be kept at different temperatures and still be viable. You can store your cannabis seeds in a dark place, at room temperature with very few problems for up to a year. But, if you intend to store cannabis seeds for a longer period of time, then storing them in a refrigerator is the best approach. Storing Seeds at Room Temperature For small seed collections, or for storing just a few cannabis seeds, buying a fridge can seem excessive. If you plan to use your seeds within a year, storing them in a dark cupboard, in an airtight container will work fine. Temperature fluctuations will cause your seeds to lose viability. So be careful not to store them in a place where temperatures change often such as a kitchen, or near radiators and heating appliances. Do not disturb your seeds unless you're going to plant them, temperature light, and humidity fluctuations can confuse the seeds, and make them waste what little energy they have thinking they are ok to germinate. Storing Cannabis Seeds in a Fridge To increase the longevity of your cannabis seeds, you can store them in a fridge. Storing cannabis seeds in a fridge is an easy way to give them a cool, dark, stable environment. This is said to keep them viable for anything up to five years, maybe even longer. You will not need a big fridge, a 4L mini fridge should be fine. It is important not to disturb them unless you need to. Temperature fluctuations will damage the seed, so once in the fridge, leave them there until you plan to germinate them. Can you Freezing Cannabis Seeds Like many things in the art of growing cannabis, this is a subject that is up for debate. And from what studies have shown, it is possible to freeze cannabis seeds and keep them viable, but it has to be done correctly. To freeze cannabis seeds, you need specialist equipment, that most growers do not have. So it is not advised that you freeze them. You can not freeze cannabis seeds in a regular freezer, without taking the risk of killing them. Some seeds can be frozen, and they will still germinate, but their genetics may have been damaged. This might be ok when you have hundreds of seeds to store, and can risk losing some, but not good for small collections. If you do freeze them, you can increase the chances of them germinating, by removing them from the freezer and letting them sit at room temperature for 24 hours, before trying to germinate them. This will give them a chance to fully thaw out before the germination process begins. Never refreeze a seed after it has defrosted. It is common consensus amongst growers, that if a seed has been frozen and defrosted, do not refreeze it as this will certainly kill it. Humidity for Storing Cannabis Seeds When a cannabis seed receives enough moisture, it will begin to germinate. During storage of course we want to prevent this, so keeping humidity low is prefered. Not too dry though, a seed is still a living thing, it is just laying dormant until the conditions are right for germination. A little moisture in the air is still needed. The Best Humidity for Seed Storage When a cannabis seed is in storage, the humidity should not exceed 10%, and if you achieve levels below 5% you can massively increase the lifespan of your seed. High humidity will not only offer you seed ideal conditions to germinate, but it may also encourage mould and fungal spores to grow. So keeping humidity down is important to the longevity of your seeds. It can be hard to monitor humidity in small containers. But, it is a good idea to add some "Desiccants" to the container your seeds are stored in. Desiccants To put it simply, a desiccant, is something that is going to remove moisture from the air. There are a number of things you can use as a desiccant, but the 2 most common are rice, and silicone balls: RiceRice will pull in moisture from the air around it. Place your seeds into a suitable container, like a 1.5ml test tube, and then, insert a rolling cigarette filter or small piece of cotton wool. On top of this, place a couple of grains of rice, and close the lid. You can also have grains of rice mixed with the seeds in their containers. But be careful to use clean rice, to reduce the risk of mould or fungus growing inside the tubes with the seeds. Silicone Balls By taking a few silicone balls, and adding them to the container holding your seeds, you can keep humidity low, and increase their lifespan. Use a tube, and place your seeds inside, and use either a small piece of cotton wool, or a cigarette filter, and place it over the top of the seeds in the tube. Then, place just a couple of these balls into the tube on top of the cotton wool, and store your seeds in the fridge. You can easily see your seeds last for over five years in these conditions. Keeping Seeds in the Dark There are three main things cannabis seeds need to germinate and grow into a seedling, warmth, moisture, and light. When storing cannabis seeds, you need to prevent the seeds from thinking it is going to germinate. By keeping temperature and humidity low, the seed will lay dormant, but light can also have an effect on them. Always keep your seeds in the dark. The idea is to trick the seed to thinking it is underground during winter time. This way it will lay dormant until it feels conditions change, whether its light, temperatures, or humidity levels in the air. How Long Can Cannabis Seeds be Stored Under the right conditions, who knows! Seeds can germinate after decades, maybe even centuries after laying dormant. A plant called " Silene stenophylla " was brought back to life after 32 thousand years after some of its seeds were germinated. Seeds are amazing things, and as long as they are looked after, they will last you a long time. If you keep your seeds at 4-5°c, humidity below 5%, and also keep them in the dark, they will be viable for decades. Thanks for reading!

- The life cycle of a cannabis plant can be broken down into different stages. Whether you're growing cannabis indoors, or outdoors, the plant will still go through these stages throughout its life cycle. It is a good idea for you to research how a cannabis plant grows, before you start your first grow. To have an understanding of a cannabis plants life cycle, will give you a head start in your grow. In this article, we will cover, each part of the cannabis plants life cycle, so you can know what to expect, as your grow progresses. If you have any questions about a cannabis plants life cycle, feel free to ask for help in our cannabis growers forum Contents Life Cycle Indoors vs OutdoorsCannabis SeedsRegular SeedsFeminised SeedsAutoflowering SeedsGerminationGerminatingSeedling StageVegetationEarly VegLate Veg and Sexual MaturityPre FlowerThe StretchFloweringTrue FlowerFlower Formation and SexingPK BoostersRipeningFinal StagesHarvest TimeWhen to Harvest a Cannabis Plant A Cannabis Plants Life Cycle Outdoors, in its natural habitat, a cannabis plant will begin growing in spring, flower in later summer, and finish in Autumn/ Fall. As the plant reaches its final stages, female plants would have been pollinated by males, and seeds would have been created. The plant will die over winter, and the seeds are preserved and protected in the flowers. When spring time arrives, these seeds will detect the warmth and moisture from the early spring sun, and begin to germinate. This process repeats every year. Life Cycle Indoors vs Outdoors When growing outdoors, a cannabis plant will detect the changes in the length of day and night, which triggers hormones in the plant to start certain stages of growth. Light Cycles Outdoors, a cannabis plant will veg during spring time, when the days are long. This is simulated indoors, with a light cycle of 18/6 ( 18 hours light, 12 hours darkness) As the days get shorter, and nights get longer, the plant will flower. This is simulated indoors with 12/12 ( 12 hours light, 12 hours darkness) A cannabis plant will go through these stages of its life cycle, as quickly as 12 weeks, and anything up to a year, sometimes even longer. Whether you're growing indoors or outdoors, the cycle stays the same, only the amount of time it takes changes. Cannabis Seeds Like most plants, the life cycle of cannabis plant begins with seed. There are techniques where you can grow plants from cuttings, but that is for another post. All cannabis plants begin from seed. There are many different types of cannabis seeds, that have different genetic traits, and different uses to a grower. In its natural environment, a female cannabis plant will be pollinated by a male, and produce "regular seeds". Regular Seeds Regular seeds are cannabis seeds that are produced naturally by a female cannabis plant. A male cannabis plant, will disperse its pollen into the air, which is carried by the wind, or pollinating insects, onto a female. The female cannabis plant will use male pollen to produce seeds. So these seeds, have 2 parents, one male, and one female. This means they will have a 50/50 chance of being male, or female. As most growers want to grow cannabis to use for recreational or medical purposes, they want to grow buds, with no seeds. Because of this, male plants are not desired around the grow room. Not only will they not produce buds, but they will pollinate the females, which will then be full of seeds. If growing with regular seeds, you will need to grow more plants than you need, as there is a good chance half of them will be male. You will also need to flower the plants early to determine sex. To save time, space, and nutrients, many growers will now only grow "Feminised Seeds". Feminised Seeds Male cannabis plants are not very useful to the regular cannabis user. So most Percy Growers will only grow seeds that are guaranteed to be female. Like a regular seed, a feminised cannabis seed has two parents, the difference here is that both of them are genetically female. Two ideal female plants will be selected from a breeders line up. These plants will display certain characteristics that are appealing to the grower. Such as big buds, lots of crystals, or mould and bug resistance. One of these plants will be treated with colloidal silver. Making Feminised Seeds By treating a female plant with colloidal silver, you force it to grow male reproductive parts. The plants stays genetically female, but produces pollen. This is used to pollinate another female, giving you seeds, with 2 female parents, making feminised seeds Feminised cannabis seeds are guaranteed to be over 99% female, with a rare occasion of hermaphrodite. If you choose a good breeder when you choose your seeds, you will not have to worry about weak genetics, so it is unlikely you will get a male or hermie. Autoflowering Cannabis Seeds Auto flowering cannabis plants also come in a feminised, and regular seed variety. The difference with auto flowering strains is in the name, they will flower automatically. This means even under a light cycle of 24 hours light, with no dark period every day, the plant will still grow flowers. Most auto growers will only grow feminised autos, and males are only used amongst breeders. For a full guide on cannabis seeds, and how each different type works, you can see our post here: Only regular cannabis seeds occur naturally in the wild. These seeds are the beginning of the life cycle of a cannabis plant. They hold all the genetic information, and will tell the plant how to grow. All you need to do to get it started it add some water, and keep it warm. Germination Germination of cannabis seed will happen over just a few days. When the seeds is in the ideal conditions, it will crack open, and a "tap root" will protrude from it. Outdoors, in its natural environment, this will happen around early spring, as the ground becomes moist, and warmth begins to come back as the seasons change. Germinating, Week 1 When you start a cannabis grow indoors, you need to simulate the outdoor environment by providing the seeds with high humidity, and a warm dark place. Most growers will germinate their seeds in with what's known as the "Paper Towel Method": Step 1: Soak the Seeds Step 2: Paper Towels Step 3: Plant it Cannabis is a variety of plant that will germinate very quickly. Within a week after first contact with water, 95% of seeds will be above ground and into the seedling stage if kept under the right conditions. Seedling Stage, Week 1 and 2 When the shoot first appears from the surface of the medium, you will see it does not have the usual shaped cannabis leaves. It has 2 small, rounded leaves, these are called cataloydons. During this stage of growth, you will be trying to imitate the spring time environment. High humidity is prefer by young plants and seedlings. For the first week of growth, you may want to use a dome, or propagator over your plants, to keep humidity levels high Just like germination, this stage will be over within a week to ten days, and you quickly move into early veg. Vegetation A cannabis plant will start to grow outdoors in early spring, anything from mid March to late may, depending on local environmental conditions. During the spring time and early summer, the plant will grow leaves, stems and branches. It will also spend a lot of energy building a good root base. This is known as vegetation. Early Veg, Weeks 2-4 For the first few weeks of growth, you may not see a lot happening above the ground. Some strains will grow quickly, some will not. A lot of energy is being put into building a good root structure. After a week or so, when the plant is stable and able to absorb plenty of nutrients, it will grow very quickly. If you're growing indoors, it won't be long before you will need to transplant into a bigger pot, and begin some training, and topping. Early veg will only last a couple of weeks, as soon as a good root structure is formed, the plant is stable and very resilient. The growth rate will increase and with in four to five weeks after germination, your will be into late veg. Late Veg and Sexual Maturity, Weeks 4-5+ A cannabis plant when grown from seed needs between 4-6 weeks to reach maturity. Even if you tried to flower it from week 1, it would not start to flower until week 4 or 5. The vegetative stage of a cannabis plant life cycle will be anything between 4 and 6 months when grown outdoors, from early spring, until late summer. This can produce huge plants. When growing cannabis indoors, the vegetative stage can be extended for many months, and in some cases years (Mother Plants). Vegetative Light Cycles As long as the cannabis plant receives more than 16 hours of light per day, it will stay in veg*. This can be used to keep a " Mother Plant" alive and vegging for years. * Only applies to photoperiod cannabis plants When the seasons change, and the plant begins to receive more dark hours, the flowering cycle will begin. But before the plant is ready to grow big flowers, it needs to prepare itself. Pre Flower, Week 1 and 2 After Flip As the days get shorter, the plants will start producing a hormone to trigger the flowering process. During the next couple of weeks, the plant will show a massive burst in growth. Indica dominant strains can grow twice their size in just a couple of weeks. Sativa dominant strains can even triple their size during the stretch! The Stretch Before a cannabis plant is ready for flowers, it needs to stretch out, and build some stronger branches. The taller it can grow here, the better chance it will have of catching pollen in the wild. It is best to try and reduce the stretch a much as possible when growing indoors. This will not only reduce the amount of space taken up by a plant, but will also keep internodal spacing tighter, for bigger buds. As the plant is still building lots of stems, leaves and branches at this stage, its demand for nitrogen is high. As the growth rate slows down, so will the plants need for nitrogen. With the end of the stretching stage, come the start of the flowering stage. This means you the plant will need different nutrients to grow properly. The stretch will begin to finish, when you first start to see signs of flowers forming. This is known as "True Flower", and is when the flowering stage actually begins. Flowering The flowering stage of the life cycle of a cannabis plant, is always eagerly anticipated. This is when the plant will grow buds, and that's what we are here to grow. True Flower, Week 2-3 After Flip Some growers will count the flowering phase from the day they "flipped". This means when the light cycle has been changed to induce flowering ( 12/12) When the light cycle changes, a cannabis plant will spend time producing a hormone to stimulate the flowering process. It takes time for this hormones to build up, and a plant will not actually be in flower until a few days after the light cycle has changed. True flower is the best guide on when flowering has begun. It is at this point you can tell if a plant is male or female, and the flowers begin to form. Flower Formation and Sexing, Week one of True Flower As true flower begins you will see the formation of reproductive organs. This is a sure sign that the flowering process has started. It is at this point in the life cycle of a cannabis plant that they begin to show signs of sex. Even if you are growing with feminized seeds, you should have a check around the plant to ensure they are female. Most growers would remove the males from the grow room at this stage. Only female are wanted unless you are breeding. PK Boosters The plants will now spend a lot of energy building flowers. This takes up a lot more potassium and phosphorus. Many growers would start using a PK booster at this stage, to give the plant the energy and nutrients it needs to build strong flowers. The flowering process will continue for anything from 6- 14 weeks, depending on which strain your growing. Indica dominant strains will flower quicker, than sativa strains. As the plant comes to the end of its life cycle the THC and cannabinoids will begin to mature. This will happen towards the end of Autumn when growing outdoors. Ripening As the terpenes mature, a cannabis plant will start to smell real strong. The pistols will begin to change to a brown, orange or red colour. This will depend on your strain. The final couple of weeks of a cannabis plants life cycle are important to the production of THC resins and terpenes. They are important weeks, the plant might look like it is ready for harvest, but it isnt. It needs a little longer to ripen. Final Stages When the plant is ripe, there isn't much more growth to be done. All that really happens from here, is the degradation of the Trichomes. The longer you leave your plant past its ripening stage, the higher chance you have of getting rot, mould, and even hermaphrodites. It is important you know what to look out for when your plant is coming to the end of its life cycle. Harvest Time For cannabis plants grown outdoors, harvest time can range from late September, to early November. This will depend on local climate. Outdoor growers need to be prepared for the bad weather that may come with autumn. Bud rot and mould can easily take hold of a crop if the conditions are right. Because of this, outdoor growers will harvest before the damp cold weather sets in. For indoor growers, plants can be pushed a little further, as you don't have to worry so much about damp and mould. You can leave your plant until it is ready to be harvested, depending on your preferences. When to Harvest a Cannabis Plant For outdoor growers, the end of the life cycle of a cannabis plant will come as cold weather sets in at the end of Autumn/ Fall. For indoor growers, the trichomes are checked for levels of maturity, and the cannabis will be harvested at the preferred level of potency. When the plant is ready, it is harvested, and hung upside down, until dry. A wild cannabis plant at this stage would have been pollinated and full of seeds. These seeds fall to the ground, and will start to grow again next spring time, when the whole process begins again Final Notes on The Life Cycle Of a Cannabis Plant After harvesting a cannabis plant, there are many ways for you to continue with that grow. You can take cuttings from the plant, and then "reveg" them. You can revert the lights back to 18/6, and reveg the whole plant. Within a few weeks, new growth will start, and you can carry on your grow with a plant that already has a root ball. Cannabis is an amazing plant, and growing it is an amazing hobby. It is resilient, hardy, and can take a lot of stress. It really is a great plant for anyone to grow. Why not get started? Thanks for reading!

- Growing cannabis can be one of the most rewarding and enjoyable hobbies you can have. But, there is a lot of information out there, and it can sometimes be overwhelming for new growers. In this new growers guide to starting a cannabis grow, we will take you step by step through everything you need, and everything you need to know. If you are new to growing cannabis, you must have a lot of questions, so feel free to ask for help in our cannabis growers forum Before Starting Your First Cannabis Grow There are somethings you need to consider before starting. You should plan properly before doing anything. This will make sure you make less mistakes, and the whole process will be more enjoyable. Legal Status of Cannabis in Your Country This is important, in most places around the world, cannabis cultivation is still illegal. Even for personal use! If you abide to the three rules of Percy growing ( don't tell, don't sell, cover the smell), even in an illegal country, you will have no problems growing a personal amount of cannabis. Security is priority! Do not put yourself at risk. Follow the rules! How Much Cannabis Do You Need to Grow? You are only here, in Percys Grow Room, because you want to grow a personal amount of cannabis. So you will not need a huge grow room, that can supply you with massive amount of cannabis. Only grow what you will need to cover your personal supply, until the next crop is done. Usually, for most percy growers, a 1m x 1m x 2m Grow tent is plenty. You will yield around 16-20 Ounces of dry buds out of a tent this size if you follow our grow guides. If you are growing cannabis with the idea of making extracts and oils, you may need to grow a little more than that. A 1m x 2m x 2m Grow tent may be best for you. But this is the maximum size grow room you will need as a percy grower. How Much Space Do You Have You will need a space for your grow tent to fit. This is a big part of the decision. You need the grow room to be out of the way, where no one will see or hear it. Usually, growers set aside a room to grow in, but some people do not have that privilege. If space will be a problem, consider growing in a small cupboard and converting it into a grow room. Alternatively, you can buy a 60cm x 60cm grow tent, and you will be able to grow a couple of plants in there. Work with what space you have, you may have to set up your grow room in your bedroom. If this is the case, you can reduce the sound of fans and other equipment. It will never really be silent, but eventually you will get used to the noise. What is your budget Starting your first cannabis grow isn't cheap! You have to buy all of the equipment, all of the nutrients and medium, pay all of the energy bills ( DO NOT STEAL ELECTRICITY!), the costs can add up. And for most cannabis users, money can be tight, especially if you are still buying cannabis from the streets, or dispensaries. You need to make a realistic budget, on how much you can spend on your first grow room. Even if you have to save for a little while, it will be worth investing as much as you can in your first set up. After harvest, you will not be buying cannabis any more, and this will save a lot of money. You can then reinvest in your set up and get better equipment. You do not have to spend a fortune straight away. If you have a low budget, start out with a small set up. When your crop is finished, you can use the money you have saved from not buying cannabis, to buy a bigger set up. The important thing is to get started! You can upgrade as you go. Once the plants are growing, you are on your way to smoking your own, essentially free, cannabis. Available Fresh Air, and Exhaust Vents. Your grow room will need a good supply of fresh air, and a place to exhaust hot humid air from the grow room. This is a crucial factor in growing. Without fresh air, your plants will suffer from many issues, and mould can easily form if you're not exchanging the air often. Find a place you think would be suitable for your grow room. Then look for places for air, and power intake. You need to be able to draw fresh air from outside preferably. And also, exhaust the air via a carbon filter, outside of the grow room. Summary of Grow Space Look for a place that is out the way of any visitors, with access to power, and fresh air. Measure the size of the potential grow space, and if possible, buy a 1m x 1m grow tent. Again, if you have space for bigger, then go ahead. But the bigger setup you buy, the more money it will cost. To help you decide what grow tent is best for you, see our grow tents guides. But it is highly recommended you go with either a 1m x 1m grow tent, or a 1.2m x 1.2m grow tent. A tent this size should easily cover your personal needs. Starting to Grow Cannabis So, you're going to do it. You have space, and you have ordered your grow tent and equipment. Maybe you have it already and now you would like to get started. Safety, is priority! Even if you grow legally, you still need to keep it quiet. People will try and steal your crop, tell no one! Nosey Neighbours Do not give anyone any reason to expect that you might be growing! If you smoke cannabis outside, and they know, this all has to stop. You need to give the impression that you have quit. It's fine being a smoker, but if you start growing, you have to be a little more cautious about who knows about your cannabis habits. Especially when living where cultivation is illegal! Be cautious when moving anything grow related into or out of the place you're growing, and always ALWAYS use a carbon filter! Be cautious of light leaks too, not only coming into your grow room, but coming out. If your neighbours often see a bright orange/ blue glow coming from a room, they might figure out what's going on. Get black out curtains and blinds the ensure no light leaks outside. Your Grow Room After choosing what grow room you're going to use, and finding out where it needs to go, you should set it up, and run it with lights on to check out the environment before putting any plants into it. Get the temperatures and humidity dialled in first, so you don't have to do it with plants in there. Ensure you have adequate intake and extraction. You should also ensure that you have "negative pressure" in the grow room. This is when more air is being pulled out, than being pulled in. Doing this will prevent smells from leaking out of the grow room. Make sure all air is pulled through a carbon filter, and then extracted away from the grow room. What Medium is Best for New Growers Most growers would suggest coco. And I personally would suggest the same. It is a perfect medium for growing cannabis, and very easy to learn from. It is more forgiving than other mediums. if you have nutrient issues, a flush and refeed can fix things up in 24 hours. You will learn alot from growing in coco, but it comes with extra expense of things like EC and PH meter. If you're growing on a budget, you may be better starting a grow in some soil. This will not only reduce the need for expensive pH and EC meters, but feeding is also cheaper. Soil will hold onto nutrients, and can feed your plant for weeks without having to add anything extra, just water. With the right potting up technique, you may not have to buy and nutrients at all until you plants are into the flowering phase of their grow cycle. You will still need to monitor ph of the soil, but you can use a cheaper model. Soil has a bigger Ph Buffer than coco or hydro. So it's easier to manage without meters. If you're brand new to growing, avoid full hydroponics setups. Learn the basics first, how a plant grows, what to expect. Then step into the hydro world if that's something you would like to do. Choosing a Strain for Your First Cannabis Grow This will be partly personal preference, but most growers, on their first grow, need something done quickly, so they can save money, and have safe access to cannabis. Because of this, an indica dominant strain is probably best for your first grow. Indica dominant strains usually have a flowering period of around 8 weeks. So growing indica will ensure your grow is done quickly. Some cannabis users prefer a sativa high. Sativas can take up to 16 weeks to complete their flowering cycle, that's without including the vegetative stage of growth. If you prefer sativa, and it's your first grow, I would recommend growing a sativa dominant autoflower. This plant will be done in around 10-12 weeks from germination, which is still shorter than the flowering cycle of the sativa. You can of course also grow an indica dominant auto if you prefer. But bear in mind, auto flowering plants should be left under lights for at least 18 hours a day. Photoperiod plants need just 12/12 for their flowering cycle. Growing autos may increase energy consumption, but it can balance out overall because of the time saved. If any of this seems confusing to you, then please see our guide on cannabis seeds: What Nutrients to Use There are two main types of nutrients used for growing cannabis. Salt based nutrients, and organic nutrients. Salt based nutrients are also known as chemical nuits. They are synthetically made, and immediately available to the plant when in the root zone. With organic nutrients, they are natural, broken down minerals. This can be from compost, feaces, animal bloods, many things. They are delivered to the medium (soil) and then broken down by the microbes. They will take a little longer to be available to the plant than salt based nutrients. Growing organic is said to bring your cannabis a better flavour, and it is better for the environment. It is also preferred when growing cannabis for medicines. If you're a new grower, just starting a cannabis grow, it is recommend you start with salt based nuits for the first couple of grows. This is mainly because problems are easier to fix. When you get a grasp of how growing works, move into organic growing. Best Nutrient Brands for Growing Cannabis There are so many, it is hard to tell you which one exactly to buy. They all pretty much have the same active ingredients, so you should consider your budget when buying your nutrients. Go with a well known brand, like Advanced nutrients, Canna, Dutch Pro and or Old Timers. See what is available to you. If you need some verification that the nuits you're buying are good enough, head into the forum and ask. Some one will be able to confirm if you're making a good choice or not. This way, you can make a well informed decision on what nutrients will be best, before starting your cannabis grow. PH and EC Meters An important aspect of growing cannabis, is the PH of the medium. No matter what medium you're growing in, the pH needs to be at ideal levels for the plant to eat properly. A pH meter is vital to your grow, especially if you're growing in hydro, or with salt based nutrients. EC is important if you are growing with chemical nutrients too. This will tell you how much food is in your water before and after you have fed your plants. Measuring EC will not only tell you if you are over feeding your plants, it will tell you if you're underfeeding too. For you plants to have the best diet, get good PH and EC meters. They will last a longtime, and be accurate for many grows. Invest in a good one. Learn to Grow! With these things being considered. You can decide on what grow space you need, what strain to grow, in what medium, with what foods. These are the most essential things you should know before starting a cannabis grow. Plan properly before hand, have everything in place so your plants can move happily into their new home. Once you have everything you need, you need to germinate your seeds. You can do that, by following our guide to germination. We have guides for every step of your cannabis grow. Research as you go, you only need to be a couple of weeks ahead of your plants. This will take a few months, you have plenty of time to learn as you go Final Thoughts on Starting Your First Cannabis Grow The best thing you can do for your plants is sign up to a forum! In our grow room, we have many experienced growers. Who have grown in all different setups. You do not have to do this alone, we can help you every step of the way, all you have to do is ask for help. If you're completely new to growing, then there are questions you don't even know to ask yet, that are important to the growing process. Keep researching through the site, learn as much as you can. Ask for help in the forum any time you need it. It is better to ask for help now, and prevent a problem, then ask for help after the problem has occured. Growing your own cannabis is the safest way to be a cannabis user. You know the product is clean, how it was grown, and you don't have to go to the black market to get it. If you are a cannabis user, then you really should consider making that move towards growing your own cannabis. Our Cannabis Growers Forum Thanks for reading!

- Growing cannabis is a great hobby, and it is relatively easy to do. With a little bit of research, and some good equipment, anyone can grow top shelf cannabis at home. The research can be made easier, with our cannabis growers FAQs. For new growers, there are many questions that need to be answered. You can always come to our cannabis growers forum and ask anything about growing. We are always happy to help new and experienced growers get the best out of their crop. Some people do not like to ask questions, and that is fine, you don't have to be a member of our forum to use Percys Grow Room. Just check out our many guides, written by experienced growers. We have devised a list of cannabis growers FAQs. Hopefully, this answers any questions you might have. If you have any questions you would like to ask, that are not on this list, then feel free to ask for help in our cannabis growers forum Cannabis Growing FAQs What temperature and humidity should my Grow Room be? The ideal temperature for vegetative stage is around 26-28c (75-80f). But a couple degrees cooler during the flowering cycle When to Harvest a Cannabis Plant The best way to tell if your plants are ready for harvest is by checking the trichomes. These are the THC crystals on the buds of the cannabis plant.Use a jewellers loupe, or magnifying glass to see the trichomes up close. All trichomes should be milky before chopping. But personal preference can be taken into consideration. See our guide on how to harvest a cannabis plant. How to Cover the Smell of a Cannabis Grow A big concern for new growers, and one of the most common Cannabis growers FAQs, is how to cover the smell of a cannabis plant. By using a carbon filter, and good extraction, the air from your grow room will be "scrubbed" of smell, before being exhausted. Humidity for Growing Cannabis The average humidity level for growing cannabis is around 50% (40-60% range is fine). Humidity should be higher for young plants in vegetative growth stage, 60-70%.When a cannabis plant is flowering, keep humidity between 45-55% to reduce the chances of mould spores germinating. What Extractor do I Need for My Grow Room? To calculate how big a fan you need, follow this equation: Length x width x height of your grow room in meters. (This will give you the cubic capacity of your room) Multiply that value by either 20 or 30 which is the minimum and maximum air changes required per hour for optimum ventilation. (30 air changes per hour are ideal for optimum ventilation).For example: A grow room measuring 2mtrs x 2mtrs x 2mtrs = 8m³, x30 air changes an hour = 240m³ per hour will need to be extracted. What light should I use to grow cannabis indoors? A 400-600w HID bulb, is a the standard amongst indoors growers, but you can also use LED and CFL lighting. Choose which light will be best for your grow space, by reading our guide on grow lighting. Should I use a pH meter? If you're not growing organically, then yes. Keeping the pH of your nutrient solution within the ideal range is crucial to healthy growth. It will help your plants to take up essential elements contained in the nutrient solution. What is the ideal pH of my nutrient solution? In hydroponic grow systems, the ideal range is between 5.8 -6.2. For coco growers, the pH tends to be kept at 5.8 during veg, and then 6.0 during flower. For soil grown plants the ideal pH range is between 6.5 – 7.5, closer to 7.0 is optimum. Should I use an EC meter? Ideally yes. It is possible to grow without an EC meter, but you will have no idea how strong the nutrient solution is. This can lead to excess nutrient feed problems which will harm your plants. Measuring EC will also give you a good idea of how much your plants are eating. If you're using salt based nutrients, it would be highly recommended you use an EC meter to get the best diet to your plants. Organic nutrients are not salt based, so will not be measured on an EC meter. Because of this, if you're growing organically, an EC is unnecessary. Find out more about EC and how it works, here. What is the ideal EC of my nutrients? This is a one of the common Cannabis growers FAQs, but its hard to answer directly. The strength of your nutrient mix is very much dependant on the age, strain, and stage of the growth cycle of your cannabis plants. Experience will give you personal guidelines that suit your growing best. General guidelines:Young vegetative plants: Start off 0.2 points above your Background ECEstablished vegetative plants: Should be around 0.8 EC, after gradually raising EC by 0.2 points, as the plants have grown.Established flowering plants: Can be anything from 1.0 to 1.8 EC. Raise EC slowly, your plant will tell you when it's too much. If it's too strong, your plants will display signs of nutrient excess. In which case, lower the EC. What if the EC is too high? Your plants will suffer lock out, and nutrient excess problems. Also, plant growth will slow down, and visibly you will see, brown spots or curling leaves on your cannabis plant. What if the EC is too low? The plants will be weak and pale and yields will be lower. They will display signs of nutrient deficiency, and will be more susceptible to bugs, and disease Can I Grow Cannabis with Hard water? Hard water, is water from your supplier, that has a lot of dissolved minerals in it like Calcium, Magnesium and other trace elements. This can cause pH instability and in some cases, will require the grower to use a hard water specific nutrient. You can reduce the amount of trace elements and contaminates in your water by using a reverse osmosis system. What temperature should my nutrient solution be? The ideal temperature for hydroponics nutrient solution is 18C. Lower temperatures cause a slowing in all aspects of growth, and higher temperatures will starve the solution of oxygen and can lead to root rot problems. Do I Have Bud Rot? If your flowers look dead, with grey or brown patches, then you may have bud rot. To be sure, you can check out our guide on bud rot, or get a picture of the problem to us in our cannabis growers forum. Keeping your grow room humidity below 55% during flower, and using plenty of fans will help to avoid this problem. But most gardeners will experience it at some point. Be extra vigilant in the last few weeks of flowering, and keep temperatures and humidity at ideal levels. How often should I change my nutrient solution? When growing cannabis hydroponically with a reservoir, you should change the nutrients solution every 7-9 days. Two weeks should be the absolute maximum. If you do not change and clean the reservoir often, then a build up of salts left behind from the nutrient will cause serious problems for your plants. Q: Should I aerate the nutrient solution? A: Always! Keeping a good level of oxygen in your water, will enhance every aspect of plant growth and yield. It will increase the amount of good bacteria in the medium, and deliver more air to the roots. Even when growing in soils, you should use an air stone to airate your water for at least twelve hours before feeding. Q: Should I use RO water (Reverse osmosis?) A: If you live in an area with hard water, then yes. Tap water in hard water areas has many contaminates and salts which are used to chemically clean the water. Some of these contaminates are useful to your plants, but most are not. By using an RO system to clean your water, you will have the perfect base for your nutrient solution. You can give your plant exactly what it needs, and know for sure what is in the nutrient solution. Q: Why are my cannabis plants wilting? A: Usually this is due to a lack of oxygen to the root zone, or the plant needs a bigger pot. It could also mean the plants being attacked by a disease. Contact us in our forum, to make an accurate diagnosis, more information is needed about your grow. Q: What causes cannabis leaves to turn yellow, brown or purple? A: There are many reasons for this happening: nutrient & pH related problems; temperature related problems within the growroom or the nutrient resevior. It may even be disease or pest attack. For an accurate diagnosis, more information will be needed. We recommend contacting us as soon as you see the problem so that we can help you fix the problem. Q: Which bugs can live on my cannabis plants? A: The most common grow room bugs are Spidermites, Whitefly, Thrips and Fungus gnats. If these pests are not dealt with as soon as they are visible, it can lead to severe plant growth problems and even death. We recommend looking here for pest solutions. Q: How do I kill bugs on a cannabis plant? A: This will depend on what bug it is, and at what stage of growth your plants are at. If you have bugs early in your plants life, you can treat with many pesticides. Neem oil is the most popular. You can mix your own pesticides by following our guide. During flower, you may not want to spray your flowers with pesticides of any kind. Using predatory bugs is an option some growers choose. But you will need to wash your buds after harvest, to remove any contaminates they leave behind. Final notes on our Cannabis Growers FAQs This list will be extended over time.

- Keeping Healthy Cannabis Plant RootsBy PERCYSGROWROOM When growing cannabis, growers will tend to focus on the parts of the plant they can see. But beneath the soil, there is the root system, which is just as important to a plant’s overall health. Keeping Healthy Cannabis Plant Roots will make sure your plant is healthy, and well fed. healthy cannabis plant roots Roots absorb water and nutrients and also hold the plant firm in the medium. If a plants roots are unhealthy, your plant will not be able to eat correctly, and will suffer from numerous nutritional issues. Here is a simple guide on how to keep healthy roots through our your cannabis grow. If you have any questions about problems you might be having with your cannabis plant roots, then feel free to ask for help in our cannabis growers forum Cannabis Plant SeedlingsWhen you first germinate cannabis seeds, you will see a tap root protrude from the shell of the seed. You have to take great care when transplanting a seedling into its medium as the taproot can easily break. Seedlings with Tap Root The roots of a seedling prefer warmer temperatures than those of a mature plant. The Growth of the roots will be fastest if you can keep the root zone temperature between 24 to 27°C. If root zone temperatures exceed 27°C the roots can dry out too quickly. Or they will be prone to diseases like root rot. There are some mistakes new growers will make with seedlings that will affect the root growth of healthy cannabis plant roots. Overwatering is one of them, as seedlings do not yet have the ability to absorb much water. Watering too much will stop the roots from breathing, and may also cause bad bacteria to grow in the medium due to lack of air. Underwateing can also become a problem since seedling roots are still young, and the isn’t a lot of root mass. If the medium dries out too much, the roots will die and not recover. Feeding young seedlings.When a cannabis seed first germinates, there is food stores inside the seed to get the root out and into the medium. It will find more food there. A cannabis seedling will not need a lot of food, and if you’re growing in soils, it is best not to feed your plant at least the first 2 weeks of its life cycle. If you are growing cannabis with cuttings, you will need to make roots grow on them before they can really start to eat and grow. By dipping the cut end of the clone, in a rooting compound, new healthy cannabis plant roots will grow. Using these hormones can greatly improve the success rate of cuttings and increase the speed at which healthy cannabis plant roots develop. As plants mature, their roots begin to grow “radially”. This means they branch out from the taproot, much like the way the plant grows above the ground. Rootlets (tiny root hairs that draw in water and nutrients) begin to grow. Root tips continue to stretch, as they search for more water and nutrients. Healthy Cannabis Plant Roots in Soil As a plant grow bigger, the temperature of the root zone should be reduce a little. Roots growing in soil will grow best at temperatures between 18 and 24°C. If the soil is any colder, it will slow down the process within the roots and the plant will absorb less water and nutrients. On the other hand, soil that is any warmer than 24°C will have little oxygen present in the root zone, effectively drowning the plant. Growing cannabis in pots will require the gardener to pay attention to the size of the root ball. Once the container has become too small for roots, it is time to “transplant” the plant into a larger pot. Healthy Cannabis Plant Roots in Hydroponics Keep the root zone of a hydroponically grown plant at around 18°C. Water in this range can hold a lot of oxygen. If the water goes above 24 °C, the plant will not be able to absorb the oxygen in the water, and it will stop eating, or even drown. You can control the temps in hydro in many ways. Controlling res temps in hydro To control reservoir temperatures, and keep Healthy Cannabis Plant Roots, insulate or cover the reservoir with something reflective like mylar or white plastic. Use the white plastic to reflect the light and heat upwards and away from the res. Doing this will keep the temps down, and also help prevent algae and bacteria from forming in the reservoir. Bacteria and algae will compete with your plants for oxygen and nutrients and can lead to root infections, and nutritional problems. You can also reduce the fluctuations in res temps by using only one airstone. The more equipment you add to the water, the more heat will be passed into it. Use one, adequately size airstone per plant, or res. You can also use a reservoir chiller to control high reservoir temperatures. If reservoir temperatures are a constant issue for you, then investing in one of these will make a huge difference in your plants health. The root mass can block up pumps or filters. If left unnoticed this can cause a damage to your equipment and more importantly, your crop. Strip clean all of your pumps after each grow and remove any roots and debris. Keep them clean and they will be reliable for a long time. Beneficial Bacteria for Healthy Cannabis Plant RootsThere are some products designed to improve root development. “Bennies” ( beneficial bacteria) can also be used whilst growing cannabis to improve the overall health of the root zone. Great White “Great White is the most advanced mycorrhizal product on the market today. The combination of mycorrhizae, beneficial bacteria, trichoderma, and plant vitamins will give your plants a strong and developed root system. This will enable your plants to break down and absorb nutrients efficiently and effectively. Also, it will increase water uptake and the overall absorption area of the root system, resulting in a healthier plant.” Rhizotonic “CANNA RHIZOTONIC is a powerful, algae based, vegetative stimulator for plant roots. It contains multiple vitamins and is 100% natural. RHIZOTONIC adds more than 60 microbiological substances that considerably speed up the growth of a balanced root environment. The various trace elements and vitamins such as B1&B2 stimulate the production of hormones and root growth, thus providing beautiful, strong white roots. If you dilute RHIZOTONIC (40ml/10 litre), you can use it to soak seeds. RHIZOTONIC softens up the seed skin, making it easier for the seed to burst and germinate. Enhances overall plant growth and chemical reactions in the plant to ensure a healthier, powerful and stronger plant. Eco Thrive ” Breathe new life into your plants with Biosys-the complete microbial solution. Biosys contains a unique blend of microbes and natural plant growth stimulants. Easy and quick to mix and use, nothing immediately improves the health of your root zone quite like Biosys. Biosys is a concentrated powder that you add to water to make what we call a ‘microbe tea’. It contains some quite complex ingredients that work on a few levels. The microbes in Biosys improve root function, increase nutrient and water availability, help with disease prevention, speed up the breakdown organic matter and improve plant growth. These organisms include; 8 Species of Endo mycorrhizal fungi 8 Species of Bacillus 2 Species of Nitrogen fixing bacteria 2 Species of Pseudomonas 2 Species of Trichoderma Biosys also contains biological catalysts to allow activation and continued growth of beneficial bacteria and fungi within the root zone – right where you need them.” Rooting Enzymes for HydroponicsThere are some products available that less living bacteria and fungi but more of the enzymes produced by them. These products do not have a shelf life, and they can be used with hydrogen peroxide. This means they can be applied in hydroponic and aeroponic systems as well as in pots. Voodoo Juice The must-have magic formula for healthy roots! Beneficial microbes in the root-zone improves the availability of nutrients and help to protect against root-diseases. Advanced Nutrients VooDoo Juice contains 6 super-strains of beneficial microbe which have been painstakingly and bred to create the best possible environment for the roots of your plants. Beneficial microbes work with the roots of your plant to provide greater nutrient availability and to help to protect against root-diseases. Piranha Advanced Nutrients Piranha is a blend of beneficial fungi that work in the root-zone to improve the availability of nutrients and help to protect against root-diseases. The beneficial fungi in Advanced Nutrients Piranha Work alongside the microbes in VooDoo Juice and Tarantula for even greater root-mass, root-health and increased nutrient uptake. Advanced Nutrients Piranha is a concentrated blend of beneficial fungi for use from rooted cutting through to the second week of flowering. Beneficial fungi create a web of mycelium which works with the roots of your plant to provide greater nutrient availability and to help to protect against root-diseases. Bugs that live in Cannabis Root zonesSome insects infest root zones and feed on and damage roots. The larvae of fungus gnats live in the growing medium and eat tiny root hairs. They appear as thin white worms with a black head about one centimetre long. Adults fungus gnats are small black flies that suck the juices out of leaves. Fungus gnats affect a wide range of plants. To treat fungus gnats larvae, treat your growing medium with a larvicide. Catch adults with yellow or blue sticky traps. You can also see our Neem oil pesticides guide for a way to kill bugs. Nematodes are another species that can harm your roots. Pest nematodes are translucent worms less than 2.5 mm long that can cause root knots and injure root tips. If infected, plants will develop distorted leaves and growth will be stunted. Treat by using nematicide or predatory nematodes that will feed on the pest variety. Final Thoughts on Healthy Cannabis Plant RootsThe root system is so vital to the overall health of your plants. Without a healthy root system, plants will display stunted growth and impaired flower production. You can’t afford to forget about the roots, even though they are below the surface. Healthy roots equals healthy plants. Get those roots as big as you can, more roots equals more shoots.10 months ago

- Cannabis is a resilient plant, that will grow, and survive under many conditions. To grow the best, top shelf cannabis, you have to give the plants the best environment possible. That can be done keeping your grow room at the right temperature and humidity for growing cannabis Some strains of cannabis will thrive under high temperatures, whilst others will be stressed to the point where they will stop growing. Always read what your cannabis plant is telling you, and look out for signs of heat stress, or other problems caused by the environment. Anything that can be said about growing cannabis is a guideline, as each plant can grow differently. In this article we will look at the ideal temperatures and humidity for growing cannabis. It will give you an idea of a good environment for your plants to grow. If you have any questions about temperatures and humidity, then feel free to ask for help in our cannabis growers forum Seedlings and Cuttings. Seedlings, and cuttings will need a higher humidity than bigger plants. This is because the roots are not well established. The plant will absorb moisture out of the air, through the leaves. So keeping the humidity high during the germination and early cutting stage is ideal. Use a dome, or a propagator over your young plants to lock in the moisture. Alternatively, you could raise the humidity of the whole grow room with a humidifier. Temperature and Humidity for Vegging Cannabis Plants. As your plants grow bigger during vegetation, and the root zone grows, your plant will draw less moisture from the air. Instead, you need to encourage your plant to evaporate more water from its leaves. The more the plant can evaporate ( sweat), the more it will drink. The more it drinks, the more it eats. Reduce humidity as the plant grows, and they will grow bigger, faster: Controlling the Stretch of a Cannabis Plant After you have flipped to flower, the next few weeks you will see a boom in growth. Your plant will go through the " Stretch". A cannabis plant can double, maybe even triple their size in the first 3 weeks of the flowering phase. This is called regenerative growth ( the stretch), and the plant does it to prepare for the formation of massive colas. The stretch be controlled by using temperature. Keep lights off temperature less than five degrees celsius lower than lights on temperatures. Read our in depth guide on controlling the stretch. The Ideal Temperature and Humidity for a Flowering Cannabis Plant. As flowers form, you will have to reduce your humidity. If humidity is too high in your grow room, you are at risk of mould and rot on your buds! Low humidity will encourage your plant to evaporate more water through its leaves. This will help your plant eat more food, and drink more water. Which in turn, will make her grow faster and bigger. By lowering the temperature during the flowering cycle, you will put your plants under less stress. Less stress means the plant can spend more energy on productive growth. Reducing the humidity during the last couple of weeks of the flowering cycle will make your plant grow more resins and crystals. To get humidity so low, you will need a good dehumidifier. How to Monitor Temperature of Your Grow Room A "Hygrometer" is the best way to see if your grow room is at the ideal temperature and humidity for growing cannabis. These devices will tell you the temperature, and the room humidity of the grow room. You must have at least one of these in your grow room. By monitoring the temperature and humidity of your grow room, you will give your plant a perfect environment. Then they can just sit back, relax, and grow fine flowers. Other Devices for measuring Temps and Humidity With the rise in technology, there are many gadgets you can now purchase that will monitor your grow room for you! Some of the products, will automatically measure and adjust your grow rooms environment to the setting you select. It is easier than ever to keep track of temperature and humidity. By offering your plant the perfect environment, you are on the way to growing perfect cannabis plants. Thanks for reading!

- The Life Cycle of a Cannabis Plant Before you can really begin to under stand how to grow weed, you need to understand the life cycle of a cannabis plant. This used to be a simple, straight forward thing to explain, but over the years, with the release of "feminised seed" and " auto flowering strains", things have become a little more technical. The life cycle of a cannabis plant can be broken down into a few sections: Germination This is when a cannabis seed has received moisture, and warmth. If the conditions are right, the seed will "crack" open, and reveal a "tap root". This root will push its way downwards, whilst a shoot will push it way upwards. Once the head of the shoot has broken through the top of the medium ( Soil/ Coco/ Rock wool), it will develop two leaves, these are called "cotyledons". They are round, and not the usual, pointy leaf, we all recognise to be the cannabis leaf. After a few days, or anything up to a week, the root system has spread out, and the leaves will begin to grow, this is when germination is complete. If you would like a step by step guide on germinating cannabis seeds, check out "Percys Grow Guides: Germination Vegetation. Once the plant has established a good root system, and a few leaves to catch enough light, they will begin the "vegetative phase" of the grow cycle. This is where the plant grows leaves, stems and branches. The plant will stay in the vegetative state whilst it is getting between 16-24 hours of light a day. Most indoor growers have lights on for 18 hours a days, with lights off for 6. This will usually be refereed to as 18/6, you can read more about light cycles, and what they mean, here:Percys Grow Guides: Light Cycles. When the plant is in "veg", experienced growers will apply certain techniques to improve the final yield of a cannabis plant. Techniques such as "topping", "Fimming" and " L.S.T" will all help increase the yield of a cannabis plant. Once the plant has reached a sufficient size, then you can change the light cycle, to induce flowering. Auto flowering strains work a little differently to this, as they will grow and flower under any light cycle, even when the lights are on for 24 hours a day! Percys Grow Guides: Auto Flowering Cannabis Plants Flowering After around four weeks of 16 hours + of light, the plant will reach " sexual maturity". At this stage you can change the light cycle to induce the flowering phase. If the cannabis plant receives around 12 hours of light, and 12 hours of darkness everyday, it will begin to flower. This is when it starts to grow the buds if its a female, and pollen sacs if it is male, ( sometimes both if you have a hermaphrodite). Percys Grow Guides: Male or Female? Usually, the male plant is no good to a grower, and is only useful to some one who is considering breeding cannabis plant. The male is very low in THC, and if the pollen reaches a female cannabis plant that is also in flower, the female will develop seeds. Most growers grow their own weed for their own personal use, through either smoking or ingesting edibles, so seeds are not a desired trait in buds. Because of this, feminised seeds ( seeds that are genetically female) are the most popular seeds used by growers, as they are pretty much guaranteed to be female. Depending on the strain, the flowering phase can last anything from 6- 14 weeks. This will depend on "Indica/ Sativa dominance. Near the end of a plants life, it will begin to loose its leaves, and ripen the buds. This is where it will need to be cut down ( Harvested), and hung to dry. Percys Grow Guides: When to Harvest a Cannabis PlantPercys Grow Guides: Whats the Difference between Indica & Sativa? The life cycle of a cannabis plant can be extended for as long as a grower needs, as long as the light cycle is kept over 18 hours a day, a plant can be kept alive for years before inducing it to flower. This is how some growers keep a "mother" plant. Growing a mother plant is a great way to keep a "Phenotype" (The particular genetic traits expressed by a plant) alive, and a continuous source of cuttings. Growing from cutting will guarantee all of your plant share the same genetics, if cut from a female cannabis plant,then your cuttings will all be female too.

- As a cannabis plant goes through its life cycle, it will consume nutrients, and store them up inside the leaves, and flowers. Flushing a cannabis plant before harvest will help remove these nutrients from the plant, giving you a cleaner, smoother product. If a cannabis plant was suffering from excess or toxicity, then flushing the medium will remove built up salts, and refresh the medium to a more suitable level. In this guide we will cover everything about flushing cannabis plants. By the end of the guide you will know how to flush, when to flush, and why. If your plants are suffering with a nutrient excess or any cannabis plant problems, then ask for help in our cannabis plant infirmary. Just sign up to our cannabis growers forum. Contents What is Flushing How Flushing WorksHow to Flush a Cannabis PlantFlushing a Cannabis Plant in SoilFlushing a Cannabis Plant in CocoFlushing a Cannabis Plant in HydroponicsFlushing a Cannabis Plant Before HarvestFlushing Before Harvest in SoilFlushing Before Harvest in CocoFlushing Before Harvest in Hydroponics How to tell if you Have Flushed Enough before Harvest Flushing a Cannabis Plant to Fix ToxicityFix Toxicity in SoilFix Toxicity in CocoFix Toxicity in Hydroponics What is Flushing Your cannabis plant will get most of its nutrients from the roots. The roots will drink the water, and along with that, take in the nutrients that are available to it. Flushing a cannabis plant is when the nutrients in the root zone are "flushed" out, by pouring lots of water through it. This is done for a number of reasons, but most growers will flush their cannabis plant as harvest time approaches, to remove any built up nutrients in the plant. Flushing your cannabis plant is especially important when you have grown using salt based nutrients. These are chemical based nutrients, and can add a harsh smoke to your cannabis after harvest, if they are not properly removed. How Flushing Works Once nutrients are removed from the medium, a plant will not only start using the nutrient stores it has built up, but nutrients will also "leach" from the plant into the medium, where it can be flushed out again. Using osmosis (high concentration to low concentration), if there is less food in the medium, than there is in the plant, nutrients will pass from the plant into the medium, in an effort to find balance. As the nutrient stores are used up by the plant, and are also leached out into the medium, the amount of salts in the plant is reduced, and this will improve the quality of the final product. Remember, you are removing the plants food here, and essentially starving it. You can only do this for a couple of weeks before the plant really starts to suffer. If the plant gets weak, so does its immune system, and it can be more vulnerable to mould and pests. How to Flush a Cannabis Plant There are many different methods of growing cannabis, so there are also different ways to flush. But no matter what method you are growing with, the principles are the same, you want to remove nutrients from the root zone, this will do 2 things: 1: Make the plant use up stored nutrients from leaves and flowers2: Have nutrients inside the plant leach into the medium You are going to need a lot of water for this, and it should be pH'd at the correct level for your medium. Flushing a Cannabis Plant in Soil When growing cannabis in soil, you have to be careful not to over water your plant. So, to make sure you have no problems like this after the flush, you should leave it a couple of days since your last feed before flushing the plants. Step 1You will need three times as much water as you have soil in the pots, for example, if you have ten litres of soil in your pots, then you should use 30L of water to flush the medium properly Step 2To make sure any left over nutrients after the flush are being used up, the water should be pH'd at the correct level for soil, which is between 6.5 and 7.0. Step 3Pour the water slowly through the soil, and collect the run off as it comes out. Pour this away. After all of the water has been flushed through the medium, the flush is over, and the soil has a lot less nutrients in it. Flushing a Cannabis Plant in Coco Flushing a cannabis plant in coco is very similar to flushing a cannabis plant in soil. The main difference is, the pH is a little different. It is very hard to over water cannabis plants in coco, so you are not at as much risk of causing problems by flushing the medium. Step 1You will need three times as much water as you have coco in the pots, so if you have ten litre pots, you should use 30L of water to flush the coco properly Step 2To make sure any left over nutrients after the flush are being used up, the water should be pH'd at the correct level for coco, which is between 5.8 and 6.2. Step 3Pour the water through the coco, and collect the run off as it comes out. Pour this away. After all of the water has been flushed through the coco, the flush is over. Flushing a Cannabis Plant in Hydroponics Flushing cannabis plant grown hydroponically is much easier than flushing in soil or coco. All you have to do to remove the nutrients from the root zone, is change the water! Regardless of what type of hydroponic set up you grow in, change the reservoir water. The pH will always need to be set to 5.8-6.2 in hydro, but the EC level will differ depending on if you're flushing to remove excess problems, or flushing to prepare your cannabis plant for harvest. Flushing a Cannabis Plant Before Harvest For growers who have grown their cannabis with salt based nutrients, flushing before harvest is a crucial step to getting top quality buds. The salts will build up in the plant, and it is best to remove as much as possible before using the plant to smoke or make extracts. The idea of flushing before harvest is to remove nutrients from the root zone so the plant is forced to use up stored nutrients to feed itself. Also, because the medium is going to have less nutrients in it, nutrients will leach out of the plant on and into the medium again. The EC of the medium will rise, and the leached nutrients can be flushed out again. It takes at least a week to fully flush your cannabis plant, and can go on for anything up to 2 weeks. This will depend on how big the plant is, and what medium you have been growing in. Flushing Before Harvest in Soil After flushing your plants with 3 times as much water as you have soil in the pots, you should let your medium dry out for a few days. This will give the plant time to take in some of the water and start breaking down the built up salts and nutrient stores. When the top 2 inches of the soil have dried, you can water the plant again, as normal, so you get around 10% run off. Do not add nutrients to any more of your feeds! Just give the plant water from now until harvest time. Around 7 days after the first big flush, you should do a big flush again. This will remove any extra salts that have leached from the plant, and give the plant its last watering before harvest. After this big final flush, you should leave the plant for 3 or 4 days to dry out, and then harvest. Flushing Before Harvest in Coco A good flush in coco will take about 10-14 days. This will depend on the size of the plant. The bigger the plant is, the longer you should flush for. Start off with the big flush of 3 times water as you have coco in your pot. This will remove all nutrients from the medium, and allow the plant to start using stored nutrients in the leaves and buds. This flush should be pH'd at 5.8-6.2. Allow the coco to sit for 48 hours, and then water the plant with just water, every other day. This will keep the coco saturated, and constantly flush out any salts that have leached from the plant. After 6 or 7 days, do one more big flush. There is no need to pH the water this time, as you want to encourage the plant to use whatever is left in its nutrients stores, by locking the nutrients out in the medium. The plant will begin to turn yellow, and can be harvested after about 3 days after the second big flush. Flushing Before Harvest in Hydroponics Flushing a plant in hydroponics before harvest is relatively simple. It can be done in about 7 to 10 days. Begin by emptying your reservoir and replacing the nutrient solution with just water. Keep topping up the res over a few days with just plain water. You're not going to feed your plants again, so from now on, you will only give your plants water with no nutrients added. After a few days, empty the reservoir again, and top it up with some fresh water. This will remove any salts that have leached from the plant into the water. It won't take long for the plant to use up their stored nutrients and within 7 to 10 days, and couple of res changes, the plants will be ready for harvest. How to Tell if you Have Flushed Enough before Harvest If you are monitoring the EC of the runoff or reservoir, you can tell when the plant is ready for harvest. As a plant leaches nutrients into the medium, the EC will rise. So by monitoring the changes of the EC compared to your background EC, you can tell if the plant has stopped leaching or not When the EC has stopped rising, and sits at a stable level around your BG EC, the nutrient stores have been used up, and your plant is just a few days away from harvest. Another way to tell if the plant is ready, is by tasting the liquid that seeps from the leaves. Break a leaf off, and taste the liquid that comes out of the stem. If it is bitter, there is still too much salt build up in the plant, and you should flush for longer If the liquid is sweet, or fruity, and lacks that bitterness, the salts have been used, and your plant is ready for harvest. In some cases however, a grower will not flush because of harvest, but because of a salt build up, or to fix a cannabis plant problem like toxicity or excess. Flushing a Cannabis Plant to Fix Toxicity Cannabis plant excess and toxicity occurs when there has been too much food available to a plant. Just like when a medium has less nutrients in it than the plant, the nutrients leach from the plant into the medium, the opposite occurs. When there are more nutrients in the medium than there are in the plant, the medium will force nutrients into the plant to try and restore balance. This forces the plant to take in more nutrients than it can use, and it begins to store them around the plant. A plant can not be forced to eat more than it needs, and it can be easy to over feed a cannabis plant. The best way to fix an overfed cannabis plant is by flushing the medium to remove salts, and gradually reducing the feed until it is at a more suitable level. Flushing to Fix Toxicity in Soils When flushing a cannabis plant to fix toxicity, you have to be careful not to reduce the EC of the medium too quickly, as this can shock the plant. Gradual changes are needed to make sure the plant isn't too badly affected. Begin by giving your plant a heavy watering, with no nutrients, just water. Use twice as much water as you have soil in the pot ( 10l pot, 20l of water). This will remove the excess nutrients from the soil. Then allow the medium to dry out for a few days. Continue to give your plant just water for its feeds, until the symptoms of the excess begin to fade and the plant returns to a healthy shade of green. Flushing to Fix Toxicity in Coco Coco doesn't hold on to nutrients as well as soil, and flushing is a lot more effective. You always need nutrients in your coco, unless you're flushing to harvest your cannabis plant. If you're flushing to fix a cannabis plant problem in coco, then you can't flush and leave the medium void of nutrients, it will be too much of a shock for the plants. Instead, give your plants a heavy flush, with twice as much water as you have coco in the pot. Remove the run off, and then feed your plants again, but this time lower the EC by 0.2 points, and see how the plants react from there. Lowering the EC might be enough to get things started again. After a few days if there are no improvements, reduce the EC of the feed again by 0.2 points. This will gradually bring the plants into the correct range and fix the excess problems Flushing to Reduce Toxicity in Hydroponics To fix a nutrient excess problem in full hydro set ups, you do not need to flush, but simply change the reservoir levels to a more suitable EC. Reduce the EC of the reservoir by 0.2 and watch the plants for sudden changes. If after a couple of days the problem hasn't start to fix itself, then reduce the EC by 0.2 points again. Slowly, you will bring the EC down to the most comfortable range for your plant. Final Thoughts on Flushing Cannabis Plants Flushing is easy, all you need is water, and some pH up or down. The medium you grow in will make the flush differ slightly, but really, it's all about removing the nutrients and starving the plant. If you have a cannabis plant that is near harvest, why not enter it into our Plant of the Month competition before harvesting? There are free cannabis seeds up for grabs, sign up to our cannabis growers forum, and enter your plant there. Thanks for reading Percy Growers, for the best result, wait until your plants have really turned yellow before chopping. The more salts you can get out, the smoother that smoke will be. Good luck with the rest of your grow!4 months ago

- Hmmm there's been a lot of talk about flushing over the different forums etc recently and theres is now a bit more evidence that it doesn't do what we want it to do. This is mostly on flushing before harvest It's something I've never done 🙂4 months ago
- The water in the plant and the medium will hold some dissolved salts in, it all about trying to get them out, buy either having the plant use them up, or flushing them out of the medium. There Is plenty of controversy behind this, just like most things in growing lol. Some people think you don't need to flush at all. IMO, you do, if growing with salt based nuits, organics is fine, but you want to get some of those unused salts out of the plant before harvesting it. Flushing does remove salts from the plant mate, otherwise the EC of the medium would not rise in the medium after the flush 😉 Something definitely gets leached from the plants into the medium4 months ago

- @ivean420 That's a very interesting paper - the first I've ever seen. 2017 too, before legalization. Makes sense though... Buddy was in cahoots with ABCann (an LP), and he's a MED patient, and it's sweet that it's as a MSc thesis too, so that's cool that this research is now being done. U of Guelph has actually been in the news a lot (relatively speaking lol) regarding cannabis research lately. I'm actually probably going back to Uni (of Sask) for a degree in Horticulture Science/Microbiology, and gonna look into these exact issues... but I digress. Some interesting results he came to.. but if you open the actual paper, he has a bunch of 'unrecoverable errors', described in the amendment right at the beginning.. The errors don't refer specifically to the part of the paper regarding the effects of flushing (sections 3.9, 4.4 & 6.2) though (at least not directly), but it does throw a bit of uncertainty into any of the conclusions he comes to. He also refers to flushing with 'clear water' which I assume is pure distilled (ph = 7.0, TDS < 20) water but.. can't be 100% sure 🧐. He also only records the concentration of N, P, K, Ca, Mg, and S as '% concentration by mass', which only gives you the overall masses of each of those elements, but doesn't necessarily separate the available/absorb-able nutrient versions (e.g., For Nitrogen, NH4+ and various nitrates are what the plant actually absorbs - not just pure N, sulfur is in sulfate form, not just pure S, etc.), from the N that is contained within the cells and other plant systems in different molecules. Same goes for all the other elements there too I think. He does make a good point that I probably agree with though - we need to be sure that it actually is residual salts that cause cannabis to 'burn black, taste harsh', etc... I'm personally not totally convinced that it is. My super soil has 2000ppm runoff when I harvest, so my plants are eating right till the end, and my shit burns whiter than a $30 piece of avocado toast. A study of some established-to-be black burning shit weed vs. nicely white burning smooth smoking weed needs to be officially done. I'm not sure what instrumentation you need to be able to compare the differences in specific molecular weights of various compounds, rather than the total elemental weights (my girlfriend is an analytical chemist and this is exactly what she does - but for uranium/potash/base metal/gold ore instead - but she isn't home right now). Then, isolate the anomalies, figure out what they are, and if they fuck up your burn. If the only difference is the shit weed comes back full of residual fertilizer compounds, then maybe we can assume it is that causing the bad smoke. But I bet we would be surprised... Just 2 cents from someone who has read a lot of scientific literature. Hopefully that makes sense.. 🤓 All that said, flushing to clear your medium of excess build-up/pH issues absolutely works though. A total different reason for flushing, however.4 months ago
- It's more chlorophyll that will make your buds burn black, if the buds are dried to quickly right? cutting out the nuits towards the end will stop the plant produce so much chlorophyll, and reduce how harsh the smoke is. Difficult one to test really. Maybe i should just chop a plant without flushing it and see the difference lol4 months ago
- @macky Yeah, improper drying definitely contributes... and your point on chlorophyll is probably on the right track. Chlorophyll's molecular chemical formula is C55H72O5N4Mg, a huge fucking molecule, with A LOT of carbon (and some N there too). My girlfriend informs me that large molecules like that are extremely difficult to break down (besides in the lab with strong acids), and I guess the more complex the molecule, the less efficient it will burn, and therefore leave more residuals.. makes sense.4 months ago

- When you grow cannabis, security is always a huge issue. Cannabis is a valuable crop, and if anyone finds out about your grow, it may be taken. It is important to know how to grow cannabis without getting caught, the more people that know about your grow, the more risk you have of losing it. In this guide, we will discuss ways to keep your cannabis grow secret, why you need to keep it to yourself and more importantly, how to grow cannabis with minimal risk! If you are concerned about security, and safety whilst growing cannabis, feel free to ask for help and advice in our cannabis growers forum Contents Cannabis Growers SecurityKeeping an Indoor Grow HiddenOutward Light LeakExcessive Noise From FansBringing Equipment into the Grow RoomDisposing of Your Crop ProperlyRules to Growing CannabisDon't TellDon't SellCover the SmellHow Many Plants is Too ManyWhat to do if You're Caught Growing Cannabis Growers Security The legality of cannabis growing is changing all over the world, some people are allowed to grow a few plants legally, other will be prosecuted for even growing one small plant. Regardless of legality, cannabis growers security is always a top priority. Even in places where growing cannabis is legal, your crop can still be a target to criminals, and you need to take security seriously. You have to take every precaution necessary to keep your crop a secret. Keeping an Indoor Cannabis Grow Hidden When you are growing cannabis for personal use, you will not need a lot of room for your grow. This makes it easier to keep it hidden, but there are still some things you can overlook, that will expose the location of the crop. Here are some tips, to help you keep your indoor grow room hidden, and undetected, it is just one of the many steps to follow if you want to grow cannabis without getting caught. Controlling Outward Light Leaks Growing cannabis indoors takes some bright lights! When the lights are on, and you open your grow room, a lot of that light will escape, and light up whatever room it is in. For most percy growers, growing indoors, you will be using a room in your house, or the loft. Lights used for growing cannabis not only give off a lot of light, but light of certain spectrums: HPS: OrangeMH: BlueLED: Purple / Red / BlueQB / CMH: White If there are windows in your grow room, or the room you have your grow tent in, you need to ensure that no light leaks to the outside when the tent or room is open. If a bright intense light of an unusual colour is seen from outside, it can easily be assumed that you are growing cannabis. There are 2 easy ways to control outward light leaks from your grow room: 1: Blackout Curtain or BlindsMake sure all windows are covered by blackout material. It's better if these can be opened and closed, as having windows that are always blacked out may also raise suspicion. 2: Cover the Opening to the Grow RoomBy having a curtain hanging over the front of the entrance to your grow room, you can get behind that, before opening the doors. This will stop the light from escaping behind you, and prevent outward light leaks. Excessive Noise from Fans in the Grow Room When you grow cannabis indoors, it is vital to the health of the plant that you have good air circulation, and a supply of fresh air. This involves fans, and it can get noisy, as more fans get added to the grow room. The fans in your grow room will never be turned off. The grow room will need 24/7 extraction, and at least one fan in the grow room to blow air around. If these are not placed correctly, they will make a constant hum throughout the grow, and that can raise suspicion if heard by neighbours. Reducing Noise from Grow Room Fans There a few easy ways to massively reduce the amount of sound coming from your grow room. As a fan spins, it vibrates, and these vibrations will pass through any surface the fans are on. You can reduce these vibrations by either: 1: Slowing Down the Speed of you Fans For some models of extractor, it is possible to slow them down to reduce their noise by using a plug in dimmer. Using these can reduce the life span of your extractor fan slightly, but it can be worth it if the sound of the extractor is too much. Try buying an extractor that is bigger than you need, and the use plug in dimmer to reduce the speed. This will still give you adequate extraction, but with a much quieter fan. 2: Hang your Fans As a fan spins, it vibrates, these vibrations will pass into hard surfaces and make noise. If you can stop these vibrations passing into solid objects, you can reduce the sound massively. Try hanging your fans inside the grow room, with bungee cords, or anything strong enough to hold them in place. This will stop the vibration from passing into the floor, and reduce the sound. 3: Place your Extractor in a Box You can easily build a box to fit your extractor into. Have padding inside this box to help reduce the vibrations from the extractor. This will stop the immediate sound of the fan hum escaping into the room, and it will also stop vibrations spreading the sound further. Bringing Equipment into the Grow Room Grow room equipment can be bulky, and hard to conceal. Especially when you need bags of soil moving into your house or grow space. When you order any grow equipment online, you should confirm with the seller, that it will arrive with discreet packaging. It doesn't matter how big or small it is, in some cases, you may not be in to receive it, and it may be left with a neighbour. Discreet packaging is massively important! It's a little obvious what you're doing if a box with the words LED grow light show up at your house. To grow cannabis without getting caught, never underestimate how important discreet packaging is. If you buy anything from your local hydro shop, they will most likely give you a black bag to cover the product, so it is already well hidden. But use your own judgement, if you have nosey neighbours, or live on a busy street, don't just take grow equipment alone into the house. By doing some regular shopping, and bringing that in, with any grow gear, will reduce suspicion from any one who might be watching. Disposing of Your Grow Properly First off, DO NOT FLY TIP!! You need to dispose of your grow equipment and waste responsibly. On some occasions, you may hear of growers illegally disposing of their crops. This is a massive rule breaker, and it will bring you trouble. Disposing of Old Grow Equipment You can take any grow equipment to the local tip, none of the equipment you have is illegal, even if you are growing in a country where cultivation is prohibited. There is never any good reason to litter the streets with used grow equipment you no longer need. Fly tipping will also bring more attention to you, and your hobby. This equipment will be found, and the police will try and trace who threw the equipment away. Dispose of your grow equipment properly, and you will reduce the chances of being prosecuted. Disposing of Harvested Crops After you have harvested your cannabis plants, there will be some left over plant matter you need to get rid of. This can be difficult. Stems, root balls, and fan leaves are all biodegradable, and they can be composted easily. This is the best option, and if you can get a composter for you old harvests, you can get rid of plant matter safely there, and have a good source of compost in the future to feed your plants. Burying the crop is always a good option. Not only will this keep the smell of the plants covered, but the plant matter will break down naturally, and fertilise the soil. You must be a respectful grower, and keep the impact on the environment, and people around you, to a minimum. Rules to Growing Cannabis Without Getting Caught If you want to grow cannabis without getting caught, there are some simple rules you must follow. These rules can not be broken! If you do, you will be increasing the risk of being caught. Follow these rules, never break them, and you can grow cannabis without getting caught: Don't Tell Loose lips sink ships. Nobody needs to know about your grow. Keep it to yourself, and only discuss it with members of the forum. Information spreads quickly, even if one person finds out, it won't be long before others know too. Growing cannabis is a great hobby, and you want to share it with others, but it is not worth the risk. It is rule number one for a reason, if you break this, you're asking for trouble. Don't Sell Selling cannabis without a license is illegal. If you are selling cannabis illegally, you are not only a drug dealer, but you are also earning a tax free income. This is not a position you should ever be in. Illegal distribution of cannabis, and tax evasion, will bring with it heavy punishments. All you want to do is grow a few plants for yourself, don't sell cannabis, it will only bring trouble your way. Cover the Smell For your grow to stay undetected, you need to make sure the smell is covered, especially when the plant is flowering and harvested. The smell of a cannabis plant can be very pungent, and if it's not filtered correctly, your location will be exposed. You can use a carbon filter to scrub the air from your grow room before it is exhausted outside. This will remove the organic particles, and reduce the smell. A carbon filter is a necessary piece of grow equipment, don't ever grow without one. Read more about the three rules on how to grow cannabis without getting caught here: How Many Cannabis Plants is Too Many Unless you grow in a place where cannabis cultivation is legal, even 1 plant is too many. You may hear rumors of it being ok to grow up to nine if you are in the UK, this is not true. If cannabis cultivation is illegal in your country, it doesn't matter how many plants you have. The bigger your grow setup, the harder it is to keep hidden. You will not have a massive grow setup, as you are grower for personal use. Stay small scale and only for personal use and you can grow cannabis without getting caught. Even if cultivation is illegal, if you can prove that you are only growing for personal use, the consequences will be far less extreme. Just keep it personal, don't get greedy, only ever grow enough cannabis to last you until your next harvest. If you are growing legally, and have been given a limit to how many plants you can grow, then stick to that limit and never exceed it! With the right techniques, you can grow a huge supply of personal cannabis with just one plant, there is never a need to go crazy with plant numbers. What to do if you are Caught Growing Cannabis If you get caught growing cannabis, it is because you have broken one or more of the rules. Hopefully, it wasn't rule number 2! Always remember the police are only doing their jobs, if you get caught growing illegally, it is not their fault, it is the politicians in your country that are to blame. Be polite and respectful and it will seriously help your case. If you are only growing for personal use, you can explain this to the officers, and things may go down smoothly. In some cases, they will take your plants, and equipment, but you may not even need to attend court. As long as you can prove that you grow for personal use, and you don't have evidence of drug dealing as well as growing, your punishment should be light, as long as you stay cool and calm.

- Flushing your medium is the act of pouring water, through your soil or soil like medium to remove excess salts, and nutrient build up, or to prepare for harvest. Things will differ slightly, depending on your grow medium, and choice of nutrients. If you're growing cannabis organically, there is no need to flush your plants, as there are no salts to remove. You can learn more about organics in our organics section. If you have any questions about flushing your cannabis plants, then feel free to ask us anything in our cannabis growers forum Preparing water for the flush To make sure you don't shock the roots of your plants, water should always stand for at least 24 hours at room temperature before feeding. This allows the water to reach a good temperature ( 18c is optimal), and also allows chlorine to evaporate. This is known as "degassing". Degassing will also give the microbes in your medium a better chance of survival. Chlorine will kill a lot of the bacteria that are very important to the health of your medium. Adding an air stone to your water to help keep a good supply of oxygen is recommended whenever you let water sit. That air will be dispersed through the water and given to the plants roots. It will also keep friendly bacteria in the water alive. The amount of water you will need, will depend on your pot size. For a good flush, you will need 3x water, as you have medium in your pots. For example: 4 plants in 10L pots. That's 30L each, 120L for a full flush. Flushing in Coco Flushing in Soil Once the water has been prepared, and has stood to degas, you are ready to begin the flush. Flushing in soil When it comes to flushing in soil, drainage can be an issue. It is very easy to over water plants when they are grown in soil. To get the best results, after flushing, you should let your soil dry out for a few days before watering or feeding again. Use 3 times as much water, as you have medium in your pots. A ten litre pot will need 30L of water for a good flush. Start by gently pouring water into the pot, wetting the medium throughly. Leave this to sit for a few minutes, to help any salts dissolve into the water. After a few minutes, continue to pour water heavily into the medium. The rush of water will push out the dissolved salts, and leave the medium fresh, with a much lower nutritional content. Remove all of the run off immediately, never let your plants sit in run off. Once the nutrients have been removed from the medium, your plants will start to eat the foods that have been stored up inside themselves. After the flush Depending on the reason of the flush, you may want to introduce new feed to the medium. Do this by feeding the plants straight after the flush, whilst the soil is still wet. Then let the soil dry out for a few days, so the roots get a chance to breathe. If you are flushing because harvest time approaches, it is good practise to let the medium dry out for a few days to let the plants breathe. Give one normal watering when the medium is dry, and then let it dry again. Once it is dry the second time, repeat the flush again, to ensure all nutrients have been removed from the medium. Leave the medium to dry, until the pots are light, before watering again. You should try and flush at least 10-14 days before harvest if you have grown using salt based nutrients. Flushing in Coco Prepare your water, 3x water as you have coco in your pots. 10L pots will need 30L of water. Pour the water gently into the pots, dampening the medium. Let this sit for a few minutes, as this will allow the salts to dissolve a little more. After the medium has sat, pour the rest of your water through the medium, and remove all of the run off. This will leave you with fresh clean coco, at a stable pH. After the flush in coco Depending on the reason for your flush, you may want to introduce food again. If this is the case, re feed straight away, with a slightly lower EC than your previous feeds. How to feed plants in coco If you are flushing because harvest time approaches, then it is best to flush a second time, around five days to a week after your first flush. Continue to water your plants with pH'd water everyday, with at least 10% run off, which is drained away. Do this for five days to a week, until the second flush. The second time round there is no need to pH the water, as you would prefer to let the plant use up any stored nutrients inside itself, instead of anything left in the medium. Thanks for reading!
