Help 1st time 12/12 from seed

Hey peeps i know its been a while since ive posted but ive sorted my germination issue with a new batch if beans, anyways i was hoping you 12/12 from seed growers could shed some light for me, basicaly ive decided i will be doing my next grow and probly many more as 12/12 from seed mainly because i preffer smaller thicker plants due to very limited space.
Now ive come to the conclusion that doing this means i will have smaller plants that flower faster than normal vegged plants so in this case i cant figure out exactly how much space i will need taking into account my grow space is fairly limited, some main points will be that i want alteast 4 plants in this box and they will be kept under a 120watt led ballast and possibly and 150watt cfl(if needed). The spectrum unfortunetly isnt exactly the most prefered but as its all ive got its what ill be using. So in a short question im asking whats the smallest space i can get away with using for 4 girls and my lighting setup, if it helps im leaning towards something like a book shelf with a diy door on the front or something similar such as an old dresser but it cant be wider than about 500mm as itll be going in a hidden space i side my cupboard. Any help is appreciated.

Start by finding a place to grow, see how many pots you can comfortably fit in that 500mm enclosure. Sprout the beans and put them under 24/0 for first week, 18/6 second week, 14/10 next week (they will stretch from here on which is a good time to lst ect), 12/12 next week and let it finish.
Nobody will be-able to tell you how quickly your strains can be done without running clones of the same strains, some will also mature quicker then others which will flower sooner.

Thanx the reply but you might of misunderstood me a wee bit, i want to do 12/12 from seed regardless of how long itll take so no need for veg. Regarding my grow area itll be inside my cupboard but still with in a grow box. Also due to the fact that 12/12 keeps plants small i only want 4 plants max

It's not that hard man. Just stick them on a windowsill for a week or two then put them under 12/12. 4 or 2 it don't matter if they are good fem genes. Regs well, better start more and pick your best 2 or 4 in a month. You don't have much light so I am thinking just 2 in maybe 2 gal pots is all you can handle. Maybe even smaller 1.5 gal pots would be better. Large root balls make large plants. Anyway. If you want 4 that's fine but it won't necessarily increase your yield.

Good genes, good medium and nutes, fan and temp control, proper care and adequate lighting, then just let it do its thing. That's all you need. I mean you should keep your expectations pretty low with your setup. Me, I would try to get a good intense light like a small HPS or better yet, a quality Cob and use that small LED as side lighting. As a matter of fact that is what I do. lol. HPS/LED.

Everything is always relative. Micro means micro period. Bout a pound prolly ain't happening from 12/12 with your lights and space.

12/12 from seed means flowering as soon as sexually mature. If you start them at 12/12 from sprout then they will stretch like mad and some will definetly mature sooner then the others, you wont really be sending all plants into flower at the same time.
At least 18/6 for the first two weeks imo

I don't think 18/6 or 12/12 is going to make a difference. I mean I just stick em in plastic cups, for up to 2 weeks total germ and sprout. Then pot them up into a 2g and under 12/12 they go. Stretch? I have experienced the opposite. Depends on the genes to I'm sure but an indica isn't a problem. Anyway, they usually don't flower until as you stated they are mature enough. So.. Also when I put them in the final pot I bury the stem at least up t the petiole leaf. I love this way to grow. It's so easy if you don't mind small plants but and as always, the good genes give it that dank. And, you can easily score 2 Oz like this all other things done correctly. It's almost as easy as growing a good auto but, you can get those old school reg genes without the ruderallis that many people hate.

Have you tried sticking to veg hours for a week or two? Definetly speeds up the seedling growth, tighter nodes and overall better growth and structure. More light = more growth / more growth = more everything

I thought the point of 12/12 from seed is to get the most growth before maturity hits? I agree it really depends on genetic/phenotype but thats always square one anyway.

Im about to start my 4th 12/12 from seed run and im going back to 18/6 from sprout.
My last run was 12/12 from sprout under 1000w hps and holy crap they ended up 15-20" by the end of flower in 1 litre pots lol, i seem to end up with wider thicker higher yielding when i start with 18/6 but i have never tested clone for clone.

If you have plenty of 12/12 sprout grows then im willing to listen up here

Fair enough but id be happy with an oz or even half an oz from all 4 put together. Its mainly experimentation at this point but ill try what git suggested and use my best 2

My last just as I said. Cup in the windowsill. Up to two weeks no more. Maybe 16/8 natural light often shaded. I think it gets them used to the light being shaded much. Into a 2 gal, under 150 HPS, 12/12. Or maybe even just a large 65 actual watt CFL. Sorry I just do like whatever I think I see it needs. Of course soon as we get several nodes 150 HPS eventually adding a 120 actual watt Mars LED. I am thinking this one started showing flowers around 3 weeks or a month. Then another 8 weeks and about maybe more than 2 Oz. Bodhi genes. Happy Frog. Maxibloom powder Lucas Formula Recipe after a month. Water when it needs it and that's it. I plucked a few fan leaves 2 uncover some lower nugs.

Also, the plant I don't think even got 2 ft tall from the pot. I hang my lights on the side, at an angle to shine even on the lowers. Kinda like verticle the micro way lol, but at an angle. 1 light on each side. Turn pot 1/3 or whatever every day. Feed or water when it needs it. Let it grow, let it grow, let it grow. That's all bro. It's stupid easy. But, again. I don't keep notes not am I looking for quantity. Just enough really good dank for myself is all I need.

Your way may be better though, I dunno man. I feel most of the growth the first 2-3 weeks is happening below the soil and once the pot has the roots boom, it goes into growing the plant above the soil. Straight into flower. I'm just saying 12/12 is fine. I even kept a sativa Dom short and fat once this way. I think you should also consider the pot size as relative to all other variables. You wouldn't want to use too large of pots growing this way. I dunno man. I'm high lol.

12/12 from seed is literally 12/12 from seed a lot of people do it

Yes pot "width" will help with stretch as well as not letting the damn things get root-bound lol.

I feel that the roots and foliage have a growth relationship, the roots seek out water untill it hits an obstruction, then foliage only grows to what its root zone can handle but the growth is also limited to the plants total metabolism such as photosynthesis,c02,temps ect... The more water the foliage uptakes through photosynthesis will cause the medium to dry out quicker forcing the roots to seek out more water which is why the foliage always explodes after a good water cycle. Ever notice the more your plants drink the faster they grow?

Sorry if i came off wrong, just having an adult conversation yes? plenty of ways to grow though really there is no right and wrong to a sucesfull harvest just as you pointed out. Im stoned as hell too right now lol jusy enjoying my beautiful day off soni wouldn't be surprised if i posted off information. It happens haha

Sunni, when i first heard of 12/12 from seed back in 2010, it was a common misconception that you had to start the seed under 12/12 lighting (it's a method that wasn't intended to be taken literally). The normal was actually 18/6 for 2-3 weeks then straight to 12/12. Same veg/seedling time but bigger plant.

I guess it was just how i first learned it, and maybe it's me thats misunderstood lol

I usualy do the window sill method but at the moment its full blown winter here and thats no place for a seedling to be imo. One thing i am worried about with 12/12 is that it gets so vold here im worried theyll die on the 12 hours of no light

Strain is a mystery as i got given it, soil is mainly perlite and potting soil(thats the best i could do currently) and nutes well if theyre still needed ill use my trusty old liquid fish crap from the gardening isle and mollases

Also i would actualy preffer smaller plants as im not too greedy, ill take what ever they give me so the pot size will defo be small

You'll want auto flowers honestly pick a shorter robust strain
Plenty of micro grows here just do some reading of the journals

I would already be using autos if i had the cash and time to buy some. Ive been told by a few people that 12/12 from seed some what creates an auto looking plant(not always but usualy has a nice fat main cola)

You are correct. 12/12 can create an auto like plant. Genes tho are always a factor. 12/12 basically just sends the plant straight to flower as quickly as the plant is mature enough as another poster pointed out. I cut my teeth on autos and still love them for getting some good dank smoke fast and easy. Everything depends on the genes tho. Dinafem is my goto for fems/autos. And I really like Sweet Seeds too. They may not be the dankest but, they work very well. Autos are just slightly easier and more friendly than 12/12 tho. Don't have to worry about your light schedule at all. Or light leaks. It's the ruderallis in it. Many think the ruderallis genetic tho, isn't pure like the old school reg genes. I neither agree or disagree. Well, I kinda lean toward the agree part. Who cares tho really. As long as you meet your goal.

So weed can be as technical as you want to make it out to be. Or as easy. You should be ok. Read up. Plenty of experienced info has been shared. Once you wrap your mind around "everything being relative". Meaning if you're micro, and on a budget, you're micro throughout. Micro lighting for a micro set up, small pots, small space and the genes should be friendly to that set up. And of course you have to give it a friendly environment, air flow, temps, water/nutes when needed. That's it bro. Noobs have a tendency to get too excited about the Science and Technicality of it all. It's great to be enthusiastic. But, I am not a weed scientist. I just use the quality genes the scientists have created and assimilate their tried and true methods into my own fast, cheap and easy grow style. We were all noobs at one time tho. I remember when I used to over complicate stuff too and wanted to do everything all at once. Good luck bro.
