why are you cutting off fan leaves?
It's kind of an experiment... I don't know, but the plant seems mostly indica because the leaves are huge at maturity, and the plant is short... I have cut off mature fan leaves all the way to the stalk from the beginning of the grow to keep them from shading the rest of the plant. It is a grow with CFL's, and as we all know, CFL's don't have that much penetrating power. I am not going to cut anymore of the fan leaves though, since it has some nice, well rounded, sturdy growth on it now. I'll be surprised, however, if I didn't shock it into becoming male. It's only a month and 3 days old and it has been growing pretty strong with 4 or 5 main colas and has stayed mildly short. Of course, it may only be short because all the cutting could be slowing growth.
I added the sand about 2 days ago to keep those little black gnat eggs from respawing those pesky critters. Tomorrow, I'll take the sand out and hopefully all those little eggs have perished...
