I appreciate the concern. I normally wouldn't do it all all, but since they overgrew so much, I only removed tiny branches that wouldn't even be big enough to clone off the bottom. Stuff I probably should have removed before flowering started. But I'm always in to seeing what works best for me, so I'll compare my next grow which are clones from this grow that I have under a 125w CFL. That way I can see if there is any noticeable difference in buds or yield. But guys! Have you heard of LA's Back Bud Building tek. I just stumbled across it last night, it's quite impressive even though it seems to not be well known, it involves snipping a tiny bit off of the top of your main colas which weirdly makes them noticeable bigger/fatter just days later.
