I just started roughing up half my AK-47 about 2 weeks into flip. I'm looking forward to seeing the difference!I know... This changes everything!!! You can even experiment with one decent bud spot. I did it early in flower when they looked like string beans. It feels so wrong and takes courage when they are so young and fragile looking. It’s like it unlocks potential fibers in that area of the plant. It didn’t do much for a White Widow, so proceed at your own risk.
