Welcome to Percys Grow Rooms Guides on Flowering Cannabis Plants.
These guides are designed to help you not only get more from your grow, but help you get a higher quality product at the end of it too.
The Flowering Phase
This is when your plants will start to grow flowers.
Male plants will produce pollen sacs, whilst females will grow buds
Photoperiod cannabis plants will need a light cycle of around 12 hours of light, and 12 hours of darkness to begin to flower.
The dark cycle must not be disturbed! As this can cause hermaphrodites.
Auto flowering cannabis plants will flower under 18/6. Some growers will even grow them under 24 hours of light, with no dark period, for their whole life cycle.

- In the early stages of a cannabis plants life cycle, you can not tell if it is male or female. If you are growing from feminised seeds, then the chances are your plant will be female. But when grown from regular seeds, your chances are 50/50. This guide will teach you how to tell if a cannabis plant is male or female. Male cannabis plants are usually only useful to breeders. Because of this, most cannabis growers, only grow females. If growing from cuttings, you should already know if the plant is female. But, you still need to keep looking out for sign of hermaphroditism. If you are having trouble identifying the sex of your plant, or suspect a hermie, then feel free to ask for help in our cannabis growers forum What Does a Male Cannabis Plant Look Like? During veg, a male plant will look the same as a female. But when they start to flower, the reproductive organs will begin to show. For the best idea, you should wait for 10-14 days after the flip. This means the flowers have started to form, and easily identifiable. How to Tell if a Cannabis Plant is Male If you find an unwanted male in your grow room, and breeding isn't your intention, you need to remove it straight away! The male cannabis plant produces pollen. If this was to come into contact with your female flowering plant, it will produce seeds. If this does happen, then your plant will be less potent, the flowers will be full of seeds, and it will massively reduce the overall quality of your finished product. What you see in the picture above, are the reproductive organs of a male cannabis plant. Once these have started forming, they will take around ten days to reach maturity, and open up. When the sacs open, their pollen will be released into the air. It will then land on the pistols of a female cannabis plant. In nature, this is how cannabis plants reproduce. By taking the pollen from these sacs, and manually pollinating the female, you can have a huge supply of seeds. But these seeds will have a 50/50 chance of being male or female. Most growers prefer feminised seeds, as these have a 99% chance of being female. Feminized seeds are much prefered by percy growers. The process of making them is a little more complicated, but you can do it at home. What Does a Female Cannabis Plant Look Like The female cannabis is the one we all know and love, and it is easily recognisable. The female, is what brings us the flowers, the buds, the colas. Everyone can recognise a female cannabis plant because we all know what buds look like. However, to be able to tell the difference between a male and female cannabis plant, you need to know what these plants look like in the early stage of flowering. How to Tell if a Cannabis Plant is Male or Female Some plants may show signs of "pre flower" after they have reached maturity, which is about 5 weeks into veg. But to be sure of your plants sex, you should induce flowering. By changing the light cycle to 12/12, and waiting for a week or so, you will see flowers forming. The tell tale sign of a female cannabis plant is white hairs. If the plant has white hairs coming from the calyxes, then you have a female plant. On the other hand, if you see a group of "balls", that hang together like grapes, you have a male plant. The male cannabis plant will usually show flowers a few days sooner than a female. It will also stretch a bit taller too. Keep an eye out for these signs, but as previously said, the best way to tell is to flower your plants, and see the actual flowers! Then you can be certain of the plants sex. What is a Hermaphrodite Cannabis Plant On some occasions, a cannabis plant can develop reproductive organs of a male and a female plant. This is a hermaphrodite. The male parts will still produce pollen and pollinate the rest of the crop. But the genetics will carry a "Hermie" trait, and you risk growing more buds that will also hermie. During later stages of growth, a male flower can be harder to see amongst the buds. Some growers assume that once a plant is female, it doesn't need to be checked for balls any more. This is not the case, a cannabis plant can hermaphrodite at any time, especially if the genetics are weak! If you have grown a cannabis plant from a "bag seed" then it is most likely to hermie at some point through its life cycle. A high amount of stress from things like: too much heat, not enough water, not enough food and an irregular light cycle, can change a plant to hermie. You must buy good genetics from the best breeders to ensure a good genetics backline. The better the genes, the less likely a hermie will occur. How to Spot a Hermie Cannabis Plant In the early stages of flower, it will be easier to Tell if a Cannabis Plant is Male or Female, as the reproductive organs can still be seen. What you will need to look out for are signs of male, and female parts growing on one plant: As you can see, on this plant, there are male, and female flowers growing together. This is a clear sign of a hermie cannabis plant, and if this is found, it needs to be removed from the grow room straight away. Sometimes, this can happen later on in the life cycle when the buds are much bigger. Because of this, you may not see the male parts forming. Instead, you will need to look out for "nanas". "Nanas" (short for bananas) will be seen protruding for the flowers of a female cannabis plant. Obviously, by their name, you will expect to see something that resembles a banana. If you have found bananas on your cannabis plant, there is a huge chance that is has hermied. Also, your plant may already be pollinated, and will be growing seeds. You can remove the bananas to reduce the risk of pollination. But this must be done carefully, if the pollen is released into the air from the "nanas", then you plants will definitely be seeded. There are certain steps you can take to reduce the chances of your crop being seeded. If you find a hermie, or a male in your grow room and it isn't wanted, check out our guide to removing them from the grow room. Final thoughts on Cannabis Plant Sex For most growers, buying feminized cannabis seeds is the normal thing to do. It gives you a good chance of having feminised seeds. As long as the genetics are strong, it is rare to encounter a male, or a hermie. If you have a hermaphrodite cannabis plant, there is usually an environmental factor causing it. To reduce the chances of future crops going hermie, read our guide on how to reduce the chances of hermaphroditism in cannabis. Our Cannabis Growers Forum Thanks for reading!

- After weeks of vegetation, your plants will be ready to flower. This is when they will display signs of their sex, either male, or female. But sometimes, you may come across hermaphrodite cannabis plants, where the plants will display male and female parts. Hermaphrodite cannabis plants are not always easily identifiable at the start of the flowering period, and some may start off as female, but "hermie" at the end of the flowering cycle, and produce seeds. Nobody really wants seeds in their buds. So in this guide we will explain how to identify if your cannabis plant has hermied, and what to do about it if it has. If you think you have a hermaphrodite cannabis plant, you should get a second opinion from our, cannabis growers forum before you kill the plant, just to be sure Contents What is a "Hermie"Female Cannabis PlantsMale Cannabis PlantsHermaphrodite Cannabis PlantsWhat Causes a Cannabis Plant to "Hermie"Going Passed Harvest TimeLight Leaks in the Night CycleEnvironmental StressBad GeneticsIdentifying a Hermie Cannabis PlantHermie in Early FlowerCalyxes or Balls Hermie in Late FlowerWhat are "Bananas"What to do if you find a Hermie in Your Grow RoomCannabis Plant PollenRemoving the HermaphroditeRemoving Pollen SacsRemoving "Bananas"What to do if you Have Seedy Buds What is a "Hermie" Hermie, is the term used for cannabis plants that have either changed sexes during their grow, or display signs of male and female flowers. This can be a problem for cannabis growers, as most prefer to have buds with no seeds in them, and a hermie will pollinate itself, and make its own seeds. Not only will your buds have seeds in them, but potency may be reduced, and the seeds that have been made, will most likely carry the hermaphrodite gene. This means any seed you groom from this plant, has a good chance of being a hermie too. Hermaphrodite cannabis plants can be used for breeding, and over time the "hermie" gene will be bred out and the strain will be stabilized. You can also force a plant to hermie, to create your own feminized seeds. You can find a guide on this process here: Female Cannabis Plants Most cannabis growers will only grow female cannabis plants. This is because the female is what brings us the buds, and high cannabinoid content. It is easy to ensure you are growing female plants, by buying feminized cannabis seeds from a good seed bank. These seeds will have 99%+ chance of being female. This removes the need of identifying and killing male plants, and will save a lot of time and space. Male cannabis plants are only really useful to breeders. Male Cannabis Plants A male cannabis plant will look the same as a female, up until it begins to show flowers. It may grow a little taller than females do in the veg stage, but until preflowers are forming, it is not easy to identify with 100% certainty, if a plant is male or female. When a male cannabis plant flowers, you will be able to tell a within a week, whether it is male or female. A male plant will develop "balls" that look like small bunches of grapes. The male parts will grow in the internodes, where the stems shoot off from branches. These can easily be confused for calyxes though, which are an ordinary part of a female plant. DO NOT GET THIS MIXED UP! If you identify a female, as a male incorrectly, then you are throwing away a perfectly good plant. Always be 100% sure it's a male or hermie before chopping it. This guide will help you: Hermaphrodite Cannabis Plants A hermaphrodite cannabis plant will display signs of both male and female sex organs. This may happen early on in the flowering cycle, and it is easy to spot. But it may also happen later in flower, and as the buds grow bigger, it may be harder to spot a hermie. We will discuss how to identify a hermie, and what they look like below, click here to skip to that section. If you are growing cannabis for personal use, then you are most likely, only looking at growing females. If you find a hermie, or a male in your grow room, it needs to be removed straight away, and the cause needs to be identified. What Causes a Cannabis Plant to "Hermie" There are two main reasons why a cannabis plant will hermaphrodite. The first being genetics. If a plant is genetically hermie, then it will grow as a hermie. The second is when a plant "thinks" it will complete its life cycle, without producing any seeds to carry its genetics into the next generation. This is mainly caused by environmental stresses, such as high temperatures, irregular light cycles, and breaking branches. But even then, if a plant has good strong genetics, it is less likely to hermie. Going Too Far Passed Harvest Time A cannabis plant will have a set period of time for the flowering cycle to begin and end. The amount of time a cannabis plant takes to flower will depend on a few factors, but mainly, it will be determined by the strain. In its natural environment, at the end of a flowering cycle, the cannabis plant will begin to die. If it has not produced seeds at this point, then it will not be able to carry on its genetics to the next generation. To combat this, a female cannabis plant can start to produce male reproductive parts, and pollinate itself. It will then be able to make seeds before it dies, and have some chance of coming back in the springtime. This can happen indoors too, if a cannabis plant goes to far passed its harvest date, it can hermie. It is important to harvest at the optimal time, not too early, and not too late. Light Leaks in the Night Cycle One of the main causes for hermaphrodite cannabis plants is light leaks during the night cycle. Light leaks are easily overlooked, but any light in the grow room, disturbing the plants night time, will cause a female cannabis plant to hermie. The best way to ensure this doesn't happen to your plants, is by making sure you have no light leaks in your grow room, BEFORE you flower your plants. If possible, take all of the plants out of the grow room, turn off the lights, and step inside. Wait for a few minutes in the dark of the grow room, and let your eyes adjust to the darkness. Within a few minutes your eyes will have adjusted, and you will easily be able to see any light leaking in that you do not want. Tape up any lights on your equipment like fans or thermometers, and seal any vents or ducting letting light in. When you are happy that there are no light leaks in the grow room, put the plants back in, and begin the flowering period. Environmental Stress Another cause of hermaphrodite cannabis plants is harsh environments, that the plant can not handle well. If a cannabis plant feels that it will complete its life cycle without being pollinated, it may hermie. This is especially important during the flowering cycle. Too much heat, not enough water, too much food, breaking branches, anything that can cause a flowering cannabis plant too much stress, not only reduces the yield, but it also increases the risk of a hermaphrodite. Take care with your plants, but even more so in the flowering period. If the plant gets too stressed for too long, it will hermie. A plant with good strong genetics will be able to handle more stress before going hermie. Seeds with weak genetics that have not been stabilized properly, will have a higher chance of hermie. Bad Genetics In every cannabis seed, there is a genetic switch, that will turn on and turn the plant hermaphrodite. If the conditions are not optimal, the chances of a hermie arising increases. When you are growing with feminised seeds, a hermaphrodite plant may have been used to make the feminised seeds at some point in their genetic history. Depending on how far back in the gene pool that hermie was, will depend on the chances of the gene rising up. Good cannabis cultivars will have bred a feminised cannabis plant over and over to make this gene more recessive. This is why it is important to spend money on good seeds, from a good reliable breeder. Don't ever grow bag seed, as the chances are, the bud you found the seed in, was from a hermie plant, or at least pollinated by a male and be 50/50 male or female. Identifying a Hermie Cannabis Plant Hermaphrodite cannabis plants will start to show female and male reproductive parts, anytime during the flowering cycle. It is easier to spot a hermie early on in the flowering cycle, as there are not a lot of flowers covering them. But as the flowers get bigger, finding a hermie can be more difficult. Hermie in Early Flower When the flowers first start to form on a cannabis plant, it will be relatively easy to spot the sex. Female flowers will grow white hairs, known as pistils, whilst the male plants will grow bunches of small pods. The male parts may also show themselves singularly, and it will look like a small ball on a stalk. This makes it confusing sometimes, as a female plant will grow calyxes, that can sometimes be confused for male parts. Make sure what you are seeing are male parts. Do not kill the plant too quickly, get a 100% diagnosis and be sure it's a male or hermie before killing it. Calyxes or Balls? At some point, most new growers will come across a calyx on their female plant, and be concerned that it is a male flower. We have all made this mistake, and if you are not sure, you have to look for extra help. There are a few differences that will help you distinguish if what you're seeing is a calyx, or a male flower. Female plants will show calyxes, they will be pointy, possibly frosty, and can have white hairs coming out of them. This is where cannabis seeds will grow, if the plant gets pollinated. If the plant isn't pollinated, they will not grow seeds. A male flower looks a little like a calyx, but, it is round, rather than pointy, it will have no hair coming out of it, and it will be on a stalk. Don't get the 2 confused, you do not want to throw away a perfectly good cannabis plant. If you suspect a male, or hermie, and you're not 100% sure, then ask for help in the forum, and get a second opinion. Hermie in Late Flower As the buds on your cannabis plant become bigger, it will be more difficult to see the male parts. They may actually grow inside the buds, and you won't be able to see them at all. Instead of seeing the usual male flowers, you will see something known by growers as "bananas". These will split open, and release pollen onto your plants, and you will soon have seeds growing in the buds. You have to be able to recognise bananas on a cannabis plant, they will appear late into the flowering cycle, and if not caught, they will fill your whole crop full of seeds. What are "Bananas" Bananas are a clear sign that your female cannabis has hermied. If you look over your buds, and find something that resembles a banana, it needs to be treated quickly. But in most cases, it is already too late, and your crop has been pollinated. The growths not only look like bananas when they are closed, but they will also open up into a star shape, much like a peeled banana. If you do find any open bananas, you can be sure your crop has been pollinated. You should check the small popcorn buds, and any calyxes to see if there is seed inside them. You may have caught it in time, and if you get the plants down soon, seed formation will be minimal. What to do if You Find a Hermie in Your Grow Room Pretty simple, kill it. But that isn't always an option. As percy growers, you really don't have plants to spare. So you have to make the most of what you have. Any male parts that produce pollen, will need about ten days before the pollen is viable, and can pollinate a plant. This gives you some time to think about the best plan of action, so you don't need to act hastily and make a mistake. Take your time, make sure you are 100% certain that the plant is a hermie before you do anything. An extra 15 minutes to make the right decision is nothing in the long run. Cannabis Plant Pollen From the first formation of the male cannabis flower, to the release of viable pollen, can be around ten days. A male cannabis plant grows slightly taller than a female, so the pollen can be lifted into the air easier and travel further. Because pollen is so light, it travels very easily in a breeze. In an indoor grow room, if pollen has been released into the air, you can be sure it's pollinated other plants. A piece of pollen from a cannabis plant can travel over 20 miles, and still be viable. Though, if it's exposed to direct sunlight for too long, it will become less viable, as the UV will kill it. If you find hermaphrodite cannabis plants in your grow room, you will need to remove it, or the pollen sacs, without spreading pollen into the air. Removing a Hermaphrodite from the Grow Room To reduce the spread of pollen, the first thing you must do when you have found a hermie in your grow room is turn off your fans. This will reduce the amount of pollen traveling in the air, and in turn reduce the chances of your plants being pollinated. The best technique for this, is to put a plastic bag over the hermie, and tape up the bottom around the pot. This will stop any more pollen getting out into the grow room. From here you can remove the plant out of the grow room, and take it far away before removing the bag. The pollen can travel far, and can make its way back into the grow room. Removing Pollen Sacs If you don't have plants to spare, and this is the only crop you've got, then you will want to try and save the plants. If you find male flowers early on in the flowering cycle, you can remove them as they grow. The pollen will take over a week to become viable, so if you stay vigilant, you may be able to remove any male parts before they pollinate the plant. To reduce the risk of the pollen escaping, and pollinating itself or a nearby plant, you should turn off your fans. Also, spray some tap water onto the pollen sac before removal. When the pollen is wet, it will not be able to travel in the wind. But because this is early in the flowering cycle, it is unlikely you will get them all, and you will be left with low quality seedy buds. It is best to find out why the plant turned hermaphrodite, fix the problem and start again. Removing "Bananas" Bananas will appear on hermaphrodite cannabis plants near harvest. If you have got this far through the grow, then it is unlikely you want to stop now, and it is worth finishing the plant off. By removing the bananas, you can reduce the amount of pollination in the grow room, and that will reduce the overall amount of seeds in the buds. Turn off your fans. Use a small plastic bag over your finger tips to pinch off the bananas. Once removed, wrap the bag around the banana tie a knot in it, and remove it from the grow room. Do this for all of the bananas you can find. It may not be ideal, and it may not get all of them, but it will at least reduce the amount of seeds in your buds. What to do if you Have Seedy Buds Finding seeds in your cannabis can be a downer, but it's not the end of the world. Just because your cannabis has seeds in, doesn't mean it isn't high quality. It just needs to have the seeds removed before you use it. It can become a pain picking the seeds out of your buds, but you can consider turning your buds into extracts. This way, you take only the oils, terpenes and cannabinoids, but leave the seeds behind. To make sure this doesn't happen again, you need to find the source of the problem, and what caused the plants to hermie in the first place. It is most likely down to a light leak during the night hours, and you should check your grow room over to make sure no light is getting in.5 months ago

- As a cannabis plant transitions from the vegetative stage, to the flowering stage, it will go through what is known as, the “Stretch”. This is different to other types of stretch that can come from stress, or light problems. The stretch is a natural part of the cannabis plants life cycle. It is also called regenerative growth. A cannabis plant will grow taller throughout its flowering phase, but for around 2 weeks after the "flip" the plant will show the most dramatic change in height and internodal spacing. Most growers like to grow dense colas, rather than lots of small nugs. Because of this, the stretch isn't a desired trait in some grow rooms. Especially as height can be an issue when growing cannabis indoors. If you have any questions about controlling the stretch, then feel free to ask for help in our cannabis growers forum Can stretch be useful Some growers will encourage stretch. It can be a good technique to prevent bud rot in susceptible strains with bigger flowers. Having more space between the buds will give better air circulation, and prevent mould spores from germinating. Why stretch can be a problem If the stems on a cannabis plant stretch too much, they will not be able to hold the weight of the flowers as they get bigger. This can cause buds to fall over, and become rotten. Also, stretched out branches will give numerous small buds, rather than big colas. Stretch is also a problem for growers with limited height. A cannabis plant can stretch so quickly, that if not checked on regularly, the plant can grow too close to the light and suffer burn. Reducing The Stretch First off, you need to consider how much space you have before you buy your seeds. Indica dominant strains will not grow as tall as sativas. If you have a small space, choose an indica dominant strain, or an auto flowering haze. Grow a Small Strain Indicas tend to have minimal stretch growing characteristics in flower compared to tall-growing sativas. Hybrids will be a little more unpredictable if grown from seed, as the phenotype may express more tall characteristics. Use blue spectrum light Because the light produced by metal halide bulbs is in the white-blue spectrum, it encourages vegetative growth and "bushyness" while discouraging upward growth. HPS bulbs are the best lighting source for flowering. However, because they have a light spectrum concentrated in the far red, and have no blue, they can encourage stretching. It is recommended to keep a MH light for up to 2 weeks after "flipping" to 12/12. Changing to HPS when you see the first signs of flowers forming will reduce the amount your plant will stretch. Flowers forming will mean the stretch is over. Minimise day/night temperature fluctuations A cannabis plants internodal spacing is directly related to the difference between day and night temperatures. Tests have shown that the further apart your day cycle temps are, from your night cycle temps, the greater your internode spacing will be. If you keep lights off temperatures within 5c of lights on temps, you will have shorter internodes. Reduce Nitrogen after Flipping Nitrogen is used by the cannabis plant for many things, one of which is growing leaves and stems. After the vegetative stage is over, the plant will use less nitrogen. It is important to reduce the amount of nitrogen available to the plants during the stretch. If there is an abundance of it, the plant will keep using it to make stems, which will inturn give you longer stems. Reduce your nitrogen in your feed by 50% as soon as you flip your lights to 12/12. This will give the plants less nitrogen, so they will make less stems and branches. Controlling Stretch in a Cannabis Plant Stretching can be a physiological reaction to a variety of environmental stresses (low light, high humidity, low/high temperatures, transplant shock, leaf loss, etc). Maintaining optimum growing conditions is your best defense against stretch. The stretch can happen at anytime during the grow cycle. For better flower formation, and a better density at harvest time, apply the following techniques to reduce stretch before flowering. Use MH lights during vegging and the first 2 weeks of flowering (during the stretch phase) for short internodes.Avoid high levels of nitrogen during the stretch. Try using a nutrient that has a ratio of (1-1-1) during the early stages of floweringControl lights off temperatures and keep them within 5c-10c of Lights on Temperatures Sign up to Our Cannabis Growers Forum Thanks for reading!

- For all the outdoor growers in here....and indoor too. How low can the temps be for the plants outside? I've heard crazy shit like has to be 15degrees C at least and I've heard people say at least above 5 or above freezing is ok for a bit....what are your guys lowest temps for the ladies outside?3 months ago
- Got down to 4 feels like 2 degrees and drizzle last night. Shook them before i went to bed and they are good to go today! Its a violator kush clone. I think genetics is the deciding factor in this question3 months ago
- I think moss is right it’s all down to genetics and how the strain has been stress tested. But as a rule of thumb I try not to let my tent get below 15oC. And I’ve started bringing in my tender plants from outside as it’s getting pretty cold of an evening now. You’ll be surprised at what temps a plant can tolerate tho ✌️3 months ago
- Genetics and how it has lived its life, its its used to the cold, itll handle it more, if its used to warm temps, itll handle them more, but big fluctuations will be a problem. As long as the frost hasn't hit it, i think youll be ok, just be wary of rot and mould3 months ago
- Ya I'm a check em close tonight. They're getting close to the chop anyways.....but it's supposed to get warmer tommorow I think....keep an eye on her. Shes almost at full potential anyways. I know that now because of you guys!!! Much love🙂🤟🤩🤩3 months ago
- @colacody Its a fine line man, where it become to risky to leave out side, and being ripe enough lol. Just keep looking out for anything doggy, first sign of any problem take it down3 months ago

- For basically this entire week here in SK, it's been down to about -1 or -2 at nights, and only got up to 8 or 9 in the afternoon. I have one lady still out in the yard (she decided to wait until 2 weeks after the other 3 to start flowering for some reason and isn't quite there yet), and while she hasn't grown too much (still chunkin out a little bit tho), she is still alive and kickin'. But yes, I agree with Mitch, Pete, and Macky - genetics are most important, as well whether or not it's acclimatized to the harsh outdoors or not. I know carrots left out in sub-freezing temps concentrate their sugars and end up tasting way better, so maybe the same happens with cannabis, but with resin. 😀 😋. Maybe not, but would be sweet.3 months ago
- I have let my hindu kush plants take a couple of frosts, it just adds colour. burns off the fan leaves but didn`t harm the buds.3 months ago
- 2 degrees feels like -2 . Was worried but reading @templegrower 's comment i feel a little more comfortable3 months ago

- Genetics 🧬 is the final decision but, This is why I like to plant my plants outside in the dirt vs pots. If the plant has been outside since spring naturally it has been building up strength for the cold that comes in the fall that in mind it is a hearty plant too, it is a weed. Last year I did a test on my last plant and left a branch to see how long it would take the cold and how long it would take to die. That plant lasted until January before it finally kicked the bucket and that was after a full week of -10. It can usually take that first frost if you have your plant thinned good enough but trichomes production stops and your plant starts depreciating in value below 15’C. That being said, I also live in a great mild location opposed to people at a higher elevation or those on the coast and prairies. Outdoors we are at the will of the gods and picking at the right time is a gamble if you are watching the weather. We all want that final push before flush but timing it with the weather doesn’t always work so we do what we can to try and extend the plants season with greenhouse etc. or we cut down a tad early.3 months ago
- Over the last few years we have seen a massive rise in purple buds on cannabis. Since legislation in Canada and the US, there have been massive advancements in the cannabis market, and one of these is in genetics. The colour of cannabis can make a real difference in market value and "bag appeal". Because of this, breeders are now selecting strain and phenotypes that express their colors easier than others. Growing purple buds can be risky! There is no proof to suggest it is stronger than "green weed" but there is plenty to say it reduces your yield. Lets go over some techniques that turn cannabis plants purple. Then you can decide if it is something you would like to try. If you have any questions about how to add more colour to your buds, then feel free to ask for help in our cannabis growers forum What Causes Buds to Turn Purple During Flower? There are many misconceptions on how to turn buds purple. Lets go over some of these first, as there is really only one good way to turn your buds purple. Food Colouring: It should be obvious, that this isn't a good idea! It will work, but the plant will not be good for smoking. Sure, with enough food colouring added to your feed, you could make your plant whatever colour you want it to be. But it will not be a clean chemical free smoke. Over feeding Nitrogen of Phosphorus: As you may have seen in Percy Grow Guides to Plant deficiencies, an excess in some foods will cause your plants to change colour. This isn't good practise, and I would never suggest over feeding a cannabis plant. Over feeding can lock out other important elements the plant needs, and it will cause other health problems. You will be more susceptible to mould, rot and bugs if your plant isn't at optimal health. You want purple weed, not weed full of food, and weed thats is discolored because of nuit burn. Starving the roots of oxygen: Again, making your plant purposely unhealthy, is not a good way to bring you purple weed.
