Oh I got it. Topping or pruning. Well if it is about this I have been doing some experimenting with this lately. I have been topping some of my friends plants at the 4th nod to keep them bushy, they have been staying low and it is making them a lot bushier, but I have read that it will not increase your overall yeild per plant. I have also, been prunning some plants in a spiral so I can get better light distribution throughout the entire single stalk. If you grow a single stalk plant, you'll get that nice single fat cola, but your plant will be taller. Compact plants will produce more buds, but smaller ones along each stalk. At harvest both plants will produce about the same amount of buds/weight. In 2 months I'll post the results of the different plants(heights/yeilds/prunning styles) I will try and do more researching on this, since I can't in the mortgage office at the moment. lol
