Yea yea,I know u can start 12/12 with autos.I should have been more on point.I've been using 5g self-watering buckets,growing some really good shwag seeds I saved.I bought a lot and got(had)33 choice seeds.I've had three nice single plant harvests this way,my last one was the best one that grew out of my 2.5x2.5x4ft growbox.I switched to self-watering 3ltr bottles.I wanna grow 4 at a time in the box.Anyway, I'm asking am I gonna get root bound?my roots are almost to the bottom(clear bottles),and I would expect some loss of yield growing this way.By the way i got over 5oz. dried,she was a BEAST!I've been harvesting after week 8,so far so good.So do you think I'm gonna get rootbound?thx ahead of time if anyone else answers I'm out.

I'm not getting you, in SOG you flower as soon as clones get roots. You really dont veg just put the clone in the medium and flip the lights. You been doing SOG with 5 week veg times?
nope. this run i am vegging for 15 days. After the clones take root i move them into beds and wait 15 days.

we will see how it goes.

currently been vegging for 5 weeks and just moving plants in and out as we harvest. basically the grow room is always going.

I have some quesions for Del or any well experienced 12/12 from seed growers, please!

1) Do the plants grow out from seed in the same structure as an auto?

2) Do they veg like an auto for 3-4 weeks before showing preflowers

3) What do you mean by 'not showing the failures' Del? Do some plants just die or do you mean you only show off your pride and joy?

4) Basically, is a 12/12 from seed grow treated in exactly the same way as an auto grow (except that u need to be at 12/12) i.e. repotting, nutes, topping, lsting ETC ?

5) i can take cuttings for clones of a regular plant after 3 weeks of 12/12 from seed, and revert back to veg with the clones without any problems?

Thanks if you could answer these :)

using 4 to 6 liter pots of soil/perlite mix with ata awa max or ionic bloom nutes and also plant magic PK, canna boost accelerator and umph power folia feeding what would be an expected yield in a 12/12 from seed sog using 2 X 70w hps and 3 x 45w cfl lights? :-/ im hoping to harvest every 2 n half to 3 months around 3-4 oz, is it doable?? :-/

Pretty mucho yes to everything, and you will always get runts(failures) plants that are smaller than the rest. My worst 12-12 which has just finished was a skunk#1 which only yielded half oz, still looks lovely but I didn't do to much to help it.

I've had a couple dozen grows in my life and I have NEVER not had at least one shitty plant in every grow, it's just the way it is! It's the token runt.

Hey guys, just wanted to know from the 12/12 growers here; do any of you trim the lower vegetation at any point? I usually do it if it's a regular 18/6 then 12/12 grow after week 4 or 5 I trim the lower portion of dying leafs and such but I'm not too sure in a 12/12 grow, the schedule is not the same. Tomorrow they will be 6 weeks from seed; both plants are in a DWC setup and about 2 1/4 feet tall both of them. They have A LOT of bush though and it would really clear up some space for the light to penetrate to the lower bud sites if I could trim some vegetation off...any suggestions? Thanks for your time guys.

it wont hurt man , just do it gradually over a few days so you dont cause too much stress and stunt them , because there 12/12 from seed you want to limit the stress as much as possible so you dont affect the yield !

Dill: 10 seeds for 30 bucks? that great! i'm looking at attitude for tomorrow. They have a crazy sell going on. I want some Pineapple express, just to say i had some. I'm getting some carmel Ice, then i get 7 free fem seeds for free. All seven are good seeds i can't call them all out but they are good.
Got some really good stuff around here recently called dill. very interesting smell. great bag appeal too, nice lime green. how'd yours turn out

my runts are always 1+ oz anyway considering I dont veg them I am fine with this.

One thing people dont talk about much, and I cant stress this enough, if you want to grow big trees 12-12 from seed its very possible you have, you must, repot asap in the biggest container you got. 7+gallons container. Now I dont know about coco but in soil it truly is the way to go. The plants dont have a lot of time to develop a good root structure so if they are not bounded they will develop a much better network of roots that will help the plants explode when they go from veg to flower.

sorry for the old pics I just want to back what I am saying...

This plant on the right was one of the runt on my previous run (not so much a runt but she didnt have all that much light on her), somehow it took her forever and it chose to grow some more when I gave her more light, she is still in the room months later now still got a while to go but she isnt a runt anymore...

How long does it take to sex a plant with this method?

go in the LED section in the indoor growing section, look at the led party cup competition, we all popped our beans in June 27th and most of us showed sex around 35-40 days I believe but they were in solo cup all along, if all goes well around 30 days.

I think as long as they show no signs of flower you dont really stress them only postponed the day they will show sex. Usually I like to let them go naturally other than LST ing but on my current runs I cleaned the bottom on all of them to give some room for a top up of SS. They were maybe 15days into flower and none of t hem really showed any signs of stresss...

How many plants would you run in a 1.2mx2mx2m tent ? i am really considering 12-12 from seed but dont know how many plants to run with , Thanks .

??????????????
I got 8 in a 3 x 3 tent, 2 in a 15 gallons (both in the same container...) and 6 in 7 gallons container, I posted a link to my youtube video earlier in this thread and you can look at my journal. I would say 1 plant per sq.ft. is kind of pushing it but I think thats how you get best yield using 12-12 from seed. If I had more patience I would probably do 6 plants in 10 gallons in my 4x5 room.
