The 12-12 From Seed Thread

I want to know exactly what the point is of giving an immature seedling 12 hours of light? Your not talkin about clones right? Your talking about actually trying to flower an immature plant, I dont get it.

Read the whole thread and you will.

People who have figured out how to optimize this process
are getting very decent yields.

...and the point is to be able to have one growing area alone
and yet to be able to harvest perpetually.

Good luck,

JD

I am not doing a whole lot of 12/12 from seed anymore but its great to go through my seeds to see what are my winning crosses, ... reveg the stellar plants and clone them. Swing by my journal in the led sub section: https://www.rollitup.org/led-other-lighting/624675-greensanta-grow.html

Lots of my plants are no longer 12/12 from seed but even as of we speak I have a few going. But at the beginning of the journal almost all plants were 12/12 from seed. Often time giving better yield than clones... granted i dont veg em too long.

I've done 12/12 fs a few different times. Does anyone know if it works the same way outside? If I threw some sprouted seedlings outside tomorrow. Would they still veg til they are mature enough to flower? Or will it be like 12/12 from clone with little itty bitty plants.?????

Even if a plant is mature within 3 weeks, thats still 3 weeks it could have benefited from veg lighting. IMO theres no point initiating flowering until a plant is mature. Even for running through seeds I bet a month veg would make the difference between a gram and an ounce per plant at harvest. But I don't have any experience with 12/12 from seed, so I am open to it. But it goes against everything I have learnt so far.

with 12/12 from seed. When a seedling sprouts in 12/12 it is to immature to flower. It takes 3-6 weeks for a plant to be mature enough to flower. You know when you start flowering after vegging for so long and the plant takes off before actual flowers form. Well seeds in 12/12 take off in the same fashion. But do it for longer. When you take a clone. That clone comes from an already mature plant. So the clone itself is already mature with zero veg time. So it will flower. Right away. Like Endo/green Santa. I've had a coule that out yielded plants vegged for over month. But with 12/12 fs. You don't want to top or train too much. So its growth won't slow down. Or the stress make it a male or hermie.

Yes this is what im saying. I have seen small clones flowered early fill up a grow space in no time and yield amazing results. But since its 12/12 from SEED that implies no clones anyway. I understand you would select breeds that mature fast, but the one I have has a 14 week flower time. It didn't show its sex until 2.5 months from seed. If I had tried to flower that straight away if it survived it would be a tall spindly plant by now unable to support its own weight let alone any buds.

Though there are numerous debates on veg time vs yield, at least to maturity there is no point using 12/12 lighting on a seedling. So then it becomes 12/12 from maturity, prior to which training techniques can be used without much negative effects, it can still mature while recovering in the mandatory period required to reach maturity, which is the same as any (logistically successful) grow.

Hey hyroot,you can grow 12/12 from seed outside it might be a little late for a seedling/sprout.If you put one out that's about to flower there will be a slight revenge time(you know the sun don't just turn on and off:)) and you might run into some freezing weather.I have pics on page 454 of a couple I did outdoors,if you want to look.They had been flowering for about 2 weeks before I set them outside.They finished in Dec. here in Tx.If I remember right I got about 2.5 ounces off each.

^^^^ sweet .....dude.... Where I'm at now its 100+ degrees in the afternoon. 80 at night and in the morning. In oct-Dec its in the 70' mid 80's. Then in Jan and Feb its 70 in the day and 30-40 at night . But with my current outdoor. I force flower. Moving them inside after 12 hours of light due to city lights and what not. So I'd do that with 12/12 from seed. I'll check yours out too.

edit:
I couldn't find yours. Wrong page number.

I would recommend lst for a 12/12 from seed.....any cutting will take some time to heal.12/12 from seed we don't have time.You can get lucky like I did with the one but they usually stunt real bad....from my experience.

Nothing special,just proof 12/12 can be done outside:)2436445d1355104940-12-12-seed-thread-1207120859.jpg2436434d1355104790-12-12-seed-thread-1207120900.jpg

Maybe instead of moving them inside everynight,you could set a trash can over it.Just don't leave the can on during the day!:)

I have a small storage closet outside a few feet away that I move them into anyway. They are in 3 and 5 gals and lst to keep some what short so neighbors can't see them.

those look good. I'm a germ a few seeds today.

Can I ask why the lids with the hole in the middle?
To help with worms and bugs.I have holes in the sides of the buckets for the roots to get a little air.Hell man ants will make a freaking bed on top if I don't have a lid:)

Edit:To begin with they were inside,self watering buckets.I had an airstone in the bottom to keep the water oxygenated and from going stagnant.
