Interesting. (And thanks for the comments!) I've been growing 1 plant in the 5 gallon pail with decent results. (There's a pic on here somewhere...) But I was getting greedy and thought maybe I could cram 2 plants in that space using LST. But I guess my fear is confirmed that there isn't really the space necessary  for a good grow. I'll stick with 1 plant in the 5 gallon pail. Thanks!
