If you dont have any other choice then go for it, Ive grown a few different strains 12/12 from seed. They finish under a foot tall, And the yeild is typically 1/8 to a 1/4 ounce if lucky. The best thing is that you can cram a lot of them inside a small stealth cfl cab. You can finish them in red solo cups like I did. But for the time spent I would grow some automatics in 1.5 gal bags. That will give you the best yeild and wont take up to much space and allow you to grow several plants at a time. I would do It if I had a shit load of bag seed, But for some good breeders strains I woulnt waste my time.
It does seem a bit of a waste knowing how much a typical photoperiod yields. Didn't think it'd be that small o an amount mind! Only found out about 12/12 from seed yesterday so just wanted a bit more info. Definitely going t stick with the autoflowers f the now. I've got 2 in a the mo and they're doing lovely
