Not into chemicals, just tap water and the sun. I too have witnessed 7 leaf count when it first started to grow on it's own from the stone cover I have in the backyard. So to me that simply says indica dominate. Grew to less than 4ft. And showed all 5 leaf as it grew. Same seeds from [same mother plant] last years, now the one growing next to it, I never caught a leaf count, meaning, spotting a 9 leaf count but it grows like sativa. Whereas, the best visual I can think of is the 5 leaf indi would grow like a punk all bunched together. This one is separated buds by its main branch.
Funny, but the hairs turned brown on me and pulled that [indi] just yesterday. The other sativa-5 leaf has yet to turn the hairs brown, and they both grew out of the stones the same time. So if you can imagine, they started young, grew as if to pull them they were ripe at that young an age. I let them grow, the new grew out of them, they died off at the bottom of the trunk, but when I cut it down near the stones to harvest, I brushed the dead leaves at the bottom off, seeds came out of it, I just planted a new season of little ones again. What the birds don't eat, the rain will wash them thru the stones. Nature takes off again.
I should mention, as those seeds drop from last year, the early part of this year, I pulled all the males. This crop this year is seedless. Glad I learned it dwarfs itself to reseed, found at the bottom first stage of growth call it. Final stage, hardly find seeds. If I do, they are not developed, just a white shell, not that deadly snake looking skin on it.
As far as I know, it's a 5- leaf count is CBD. 7-leaf is indica. 9-leaf is sativa, and they are THC dominate. Fat leaf is afghan or indica, and thin leaf is sativa. Correct me if I'm wrong on this.
