Hi all,
Going start a grow journals, its in early stages right now as I am half way through building my new setup.
Well this is the design
The reason why the flower room is this size, is get the best harvest for the lights and floor space used.
My best harvest have always been in the smaller flower room, easy to harvest and you get the massive cola's, don't think it makes that much difference on the yield, (just don't get the popcorn buds lol)
So because I am between grow rooms right now, but want to be ready in a few weeks if I start the new flower room, I want my plants to be small but grow massive in a short time so I took cuttings 4 weeks in flower, the clones would be stress and it would stunt the growth up to about 6 week (monster crop).
So here are my 9 English OG plants, Lady sativa Genetics (looking a little sorry for them self), 8 of the 9 plants look good but I always take 50% more clones than I use, so you can keep the best and chuck the rest.
The leaves will sort them self out in about 2 weeks and I will pot them up.
do like the jacks magic soil, use a garden sieve to remove any lumps, add 20% sand or per light, never want water logged.
dry nutes for flower
garden lime (very strong)
fish,blood and bone
bone meal
kelp meal
chicken shit (very strong)
The dry nutes keeps the plants healthy till harvest (I use 15ltr pots ).
Nice mate!! Looking forward to seeing this one!!
Its going to be good fun, finished building the shed last week, fully insulated, hand built and designed to keep the grow space hidden in my shed (well as much as I can)
wife gone mad because it cost me a £1000 for a 2.7 (w)x 2.3 (L)x 2.5(H) shed
inside its 2.4 x 2 x 2.3 ( use 4x2, 22mm chipboard and 20mm cladding overlap)
but I love it, going to make it my man cave kind of thing( love a bit wood work, programming(android studio and just playing around with the Arduino).
so I can keep it all out the house to keep the wife happy.
@jacks_farm wow man, awesome job, great craftmanship. I find it more and more appealing to do as much as possible by your self. The satisfaction I get from eating the food I grow, smoking the herb I grow, growing in the room I built. There is so much potential in us human beings, it can only get better.
Cheers brother, stay safe and happy!

Totally agree with you @galandil
In some ways it makes life hard when there is so many strict rules to follow and thinking outside the box is frond on.
Not great with names or written English but love to design and build everthing you can think of, not the best by any means but never giving up on anthing I have tried to do and its normally by myself,
I have a large A frame green house built in a way thats very effective, traps the light and heat with a raised beds(12" heigh) all around the sides, greenhouse is about 9ft (L)x 6ft(w) x 8ft heigh in the centre, used polycarbonate sheets and it cost me less than £100 ( frame is made of 6"x2" treated cls, as it was going cheap and I could convert it into a shed later if I need to, it very strong frame lol ( cost about £300 in total) grew loads of veg, had problems getting in the greenhouse towards end of the summer with the plants taking over 
love playing around with computer and programing as it's all basic logic and I love it
Quick Update
Just been to the shop and got
2 x Medium Defender Reflector by Adjust-A-Wings
8" rhino 400mm filter,
5m insulated 8" ducting
digtal 600w hps ballast
2 x new bulbs
My room is finally set up, took a long time to get every thing dialed in.
built a cupboard next to the groom and placed a 6" extract fan in the center and covered it with 100mm Rockwall to reduce the noise and this worked really well.
used 6x 120mm main server fans
4 fans to pull cool air into the grow room and over the canopy towards the HPS bulb (low watt fans)
2 fans (high watt) to pull hot air up between the hoods (30cm) away from the canopy
(outside temp 11c) one hps light on for an hour, canopy temps 23c, so turning a second lights on is not going to be a problem this time of year.
so next is checking the light spread (don't know the ideal lux, so I went for an even light spread, took hours to work out)
my guess is starting the hood 90cm (first week in flower) above the canopy will be work great and I will start to get problems when there is less than 35cm between the canopy and hood, the filter as one end of the flower room, it stops me lifting the hood more than 130cm so its not great but I don't need to plants to grow much more than 3ft height (including pot).
The plants are in but I forgot to water them yesterday and the looked slightly wilted (tops leaned over) but recovered over night so I will see how they look in a few days
sieved the soil and added some sand, 20% of the soil was twigs, stones and roots so that went in the bin.
8 plants where potted up in 5ltr pots.
Dealing with the cooler weather .
I am going to set all 6 fans to switch on and off with the lights as this will reduce the intake air into the grow room and should reduce the humidty as it causes a larger vacuum when the lights out and I will set the tube heater to switch on when the lights out, with the reduced intake air, this should give the tubes time to heat the cool air.
Also going build a veg room and have the air circulating both rooms to keep veg room cooler and flower room warmer.
@jacks_farm I've read that the first 15 minutes in darkness, the plants transpire lots thus raising the humidity. Has that been your experience?

Never thought about this but it does make sense.
You can think of temperatures and humidty on a set of scales because as the temperature goes down the humidty goes up, this is where most growers get caught out and you get bud rot in late flower.
also when you have the fans on auto to control the temps, the vacuum reduces and this inturn will increase humidty and reduce airflow increasing the chance of bud rot.
there so many things you can do to stop bud rot but I could go on for hours about this.
Cool setup man, looking forward to seeing some pics 
Are you UK based?
managed to get my fan silent, took some time and planning but this is what I came up with,
A top cupboard where I can hang a 6" fan and wrap it in loads of Rockwall and use 8" Acoustic Ducting and a 8" filter to reduce it to a whisper and it works
just need to fill and paint it at some stage
here my shades and center fans pulling heat up from the lights towards the filter
Two fans each side drawing in cool air from under the shed up under the canopy towards the two fans in the center of the hoods to create a powerful upwards cool airflow without overdoing it and at the same time keeping the sound to a minimal (not as good as the extractor fan but still can't hear outside the shed)
1ft tube heater behind each set of fans so it don't take up any room but can heat up cool air entering the flower room as this should be more effective.
a bud shoot from my last grow
Somebody tried getting in my last shed so I made this shed like a tank, side view of my door with a chub lock (well that's what they used to be called) in 4"x 4" (side of door) with 1" cladding on the font and 22mm chipboard on the back fully insulated and light proof
OK, I have to ask because I always look at the maintenance side of life because that’s where my life experiences take me. If you fill and paint how will you get to the extraction fan for maintenance or replacement?
Random acts of kindness make the world a better place
@monkeydo That's a good point
Only going to use 3-4 screws and I will give the screws one layer of paint, so it will take me a couple of minutes to dig the paint out and replace the fan/screws and put the board back up
A good quality fan should last years.
@monkeydo thats was the first thing I thought about, when I saw the picture. But Jack_farm has it all figured it out
Trying to get a better understanding about lux with HPS bulbs.
How Many Lux Does Cannabis NEED
what do you fellow grower think about this video ?
Lux is for humans, light for growing plants is measured in PAR output which means photosynthetic active radiation. It measures the light energy in the specific spectrum that the plant can use. There are some internet sites that have conversion factors for lux to par on certain kinds of lights. They are just estimates tho so for my use I simply purchased a PAR meter and used the standard growing charts to set up the grow. For me the cost of the meter was well worth the information it provides me.
Random acts of kindness make the world a better place
I was just watching this,
Light lux meter App to PAR meter hack | Android Smartphone PAR meter hack
your right about the Lux is for humans but its the only free way of getting a basic idea of how much light the plants are receiving.
looking online, a lot of the hoods footprint makes no sense !
a 600w HPS meant to cover up to a 5ft x 5ft grow space but really most 600w hps hoods cover a 3ft x 3ft footprint with a good amount of par (over 500)
Here's an example of a 1kw HPS light in a 4ft x 4ft.
Really like to understand things in-depth and spend a lot of time looking things up online.
had a idea this was the case so I built my room based on half the light reflecting back on the plants to increase the lums round the edges/corners of the flower room
and I think it worked based on the video
Yer, I generally use those PAR maps to choose which light is best to purchase but I always use my meter to set up the grow because like you, I don’t really trust those maps 100%. Dead spots around the edges of HPS are a well known issue. I’ve heard of some growers using some small leds to supplement the light around the edges to get more even coverage.
Random acts of kindness make the world a better place
That's a great idea with the led's.
because the biggest problem is, if you grow a large plants, the cola's lean on the walls and fall into the corners of the room where the lums are low so mid
/late flower your plants are not getting all the light they need and its going to reduce the harvest quite a bit.
Its alway hard when you look at your plants every day after messing them up!!
Hoping they will survive, so easy to give them a little extra water or drop the light a little closer or remove some of the dead fan leaves, add more airflow, thinking what else can I do, to help my plants?
but I know from experience that would be a bad idea and make things worse!!
so I lift the pots to make sure they don't need to be watered and check the temps
After 5 days I check the plants and there a glimmer of light as I see some new growth on one of the plants.
Some of the other plants have some new growth but it's still early days.
Yesterday I look at my plants and the pots where not light but the top 2 inches of soil was dry and the soil was drawing away from the sides. 
As the plant are still very small I was unsure if the roots would reach the damp soil at the bottom of the pots, so decided to water the plants very slow and aim round the stem so the water does not run down the sides and out the pot.
I spend a good 2 mins wateing each plant about 700ml, so there a little run off, plants are in 5ltr pots (about 4 ltrs in each pot)
6 of the 8 plant are looking healthy and bushing out so I will keep the best and chuck the rest.
After watering the plant I like to watch them and see what they tell me (takes about 3 minutes)
If the leaves drop after watering( claw ) I have watered them too early.
2 days later and the plants are growing fast, temps are good between 22c and 25c (tube heaters on) and the hood sitting about 60cm (24") above the canopy.
going to pot them up in buckets soon
I have 3 bags of Gro-Sure All Purpose Compost with 4 Months Feed, Its not the best soil but going to sieve all the lumps out and add a bag of sand and some dry food :
fish blood and bone NPK 3 - 9 - 3 Encourages strong, healthy rooting
Seaweed Enhanced NPK 3.6 - 4.8 - 1.4 condition soil and Trace Nutrients
Chicken Manure Pellets NPK 4.5-3.5-2.5 + Trace Elements slow release Feeds for 3 months.
garden lime enriches soil with calcium and magnesium and helps to Adjust the pH Level Natural
its a budget grow but that see how it turns out.
thanks whitewidower,
only giving them a few more days in veg and I will be flowering them off in 15ltr buckets,
going to top a few of them, going for small bushy plant( 2-3ft high)
use some mesh to hold the shoots/buds in place.
