What was your final decision on topping Grnman? I've never done it, but from reading the threads in Email's post it looks like it should be done before flowering? Since I started flowering my plants, they are growing insanely fast, but like I mentioned to you I have a pretty hard harvest deadline and I'm afraid at this point topping will slow my flowering down by a few weeks that I just don't have. So maybe LST is my answer.
