Well. As for flower, it all really depends on the strains. Rhino is mostly indica dominant, therefore flowering takes about 6-8 weeks. Now, that 6-8 weeks really depends on when the plant shows its sex, not when you kick it to 12's. So, the answer comes with a question, when did your (hopefully) pistils pop? As for mine, i just recently started up another grow after the move, and went with some bag seeds i found off a guy. I got lucky. 2 seeds found in bags of good good. Both germed. 2 different strains, 1 more indica dominant, 1 more sativa. Both female. (That crap will never happen again, lol.) The two originals are about 2 weeks into flower at about 1.5' and 2.75' with 5 clones of each happily plugging along hitting about 6" each. Clones are about 3 wks old from the mothers and the mothers are about 2.5 months old. Mothers have flowers sprouting everywhere, but no bud yet. Im honestly thinking any day now it will start forming up. Also, you running any CO2?
