About the only thing I'm really wondering about is that I've read that the plants should be about 18" before cloning. I really just want to have 2 mama's out of the bunch. But if my 2 biggest are at 7" now, am I even going to be able to make it to 18" before cloning to detrmine sex? Will they pre-flower even during the 18/6 light schedule?!? I appreciate all the input!!
