I'm OK with busting them down. I've been considering it. I think it could help the yield since it would allow me to get more light down into more of the plants. As it is, the tops are right at the lights but most of the plant is two feet down.
That's a very good point! I forget that when I see the tall elegant plants.
Indoors, we only really have 12-18 inches of canopy, max.
