I might have already mentioned this somewhere on the forum, but... I had six plants, all different strains, three were topped and three were bent. I averaged each group of three to try and get a better sense of general outcome, and the total of the three that were bent produced 48% more weight than the total of the three that were topped -- and the smallest and biggest of each group held close to that ratio. That was significant enough for me to reconsider my methodology. It's a small sample, so it could be coincidence, but I'm willing to change. If you give the comparison a try, I'll definitely be watching...
