bob, I regularly grow according to your intentions there. I'll be interested in seeing you SOG develop. I just kicked my light down from 18/6 to 14/10 to get the fast growth going. I'll have a branch(read that "bud") growing vertically about every 2-3 inches over my entire growing surface in a week or so -- then I'll go to 12/12, yada yada.

GN -- Without getting into the possible genetic link to purple stems, can you tell me which is the more likely cause -- ph/nutrient or temp? I commonly have purple stems on my plants. It's never seemed to be anyting more than color, and this is the first I've heard that it's a bother. Am I missing a vital health clue here?
