Good question, I just tried 12/12 from seed for the first time in the 12/12 party cup thread. Amazing to see what some strains can do even in a paltry 16 oz. party cup. FYI, I'm just growing out some clones and seeds and decided to try 1Gal fabric pots for this. Will be throwing in 4 total under a 100W actual draw chinese LED and just let them grow, no training other than will FIM them once at around 2-3 weeks. From what I've seen in the party cup thread and the 12/12 from seed thread you can grow out some nice plants in 1Gal and 2Gal pots. I'm going with 1Gal and trying 4 different strains, 2 indicas, 2 sativas, just to see if I can find one that does well in 12/12 from seed/clone and the difference between strains in a small container like that. The biggest pain I've found doing them in party cups is having to water/feed them every other day, sometimes daily, the 1gal pots should be good for 2-3 days between watering I'd think.
