from your pics it looks like you keep them in the rockwool so obviously they will have to go into bigger ones, like with soil the rule of thumb being 1 gal of pot space for each foot of growth. sorry for the thread hijack! is there somewhere we can discuss this? i've been interested in growing non soil but as i said i don't want to grow in a hydroponic system, and i hate dirt, espeically sweeping it up after transplants and the such!
p.s. I've been looking for a somewhat exact nut schedule and i did imagine it takes a while(years) to develop an almost perfect routine, so i wouldnt talk crap or tell you different!
