Leaves are removed starting in veg stage when they are about 6" tall with a couple of sets of fans. Leaves are removed again every 2-3 weeks or whenever things get a little shady.
Why is the first pic during flower, if it starts during veg? (16 day before def.)
Why do the plants in the back look just as full (minus the leaves).
I do it when needed, but I'll tell ya . By just doing it isn't going to give ya more weed.
12 z's in a 32" space?
Looks like 6 plants giving 2 z a piece.
IMO definitely no high-yield technique. Just MO.
