Hey Epix, I have another question for you. I (perhaps foolishly) put 2 strains into my aero-cloner which is courtesy of your DIY. The leaves have gone, yellow-transparent mainly (& predominantly) on just one strain, but partially in the other too, but to a much less extent, It has been about 5 days, and there is very little evidence of roots beginning, and I know my pH is high, I am getting some pH down tomorrow. I think I may have to take a few misters off to restore some H2O pressure as there is not much (396GPH, wtf?), but I figured since I saw H2O dripping from the inside top of the lid, they were ok. The first signs of it came on rather quickly, I woke up the next AM after taking the cuts, only to find some hurting babies, This makes me suspicious of the H2O pressure. Is it crucial that the stems are in good contact with the spraying H2O? I still have them under the humid dome, and (4) T5's. The water is RO, and the entire cloner is itself sitting on a seedling mat.
