Eh I was in the all natural camp for a long time. I tried tucking the fans back to provide more light penetration, but the plants were just so damn bushy. Tucking the fans back just seemed illogical considering they weren't getting any light. I read all the forum post I could about defoilating and it was nothing but people arguing constantly, so I decided to do my own experiment. Turned out with my strain mild defoilating actually increased my overall yield and made my space much more manageable. The spots I pruned healed up within 48 hours, and bud production below the colas increased.
I certainly don't recommend it to newer people, but it's what I do. What you are doing will absolutely in no way harm your plants. I would prefer to spread mine out a bit instead of defoilating, but I have extreme space constraints.
Cheers.
