Well, I switched to 12/12 a couple days ago and have already determined that I have 1 male (removed this morning) and 1 female. The other two were not as mature and are not showing yet. I will post some pictures when I get home from work this evening. I made several mistakes this go and already have plans for next time. The first thing I plan to do is seperate my room. Maybe use the bottom 3' for a mother and rooting clones using 3 2' 2xbulb flouro ballasts. I am also considering trying Hydro. I should end up with two girls this time. I doubt they are going to supply me with enough bud to keep me happy until next harvest. Live and learn, right? Peace
