Good ole string, I'm getting the lazy LST method down to a science. I think I've mostly got it figured out, although strain varieties still toss me a curve. I just let it grow how many nodes/tops I want, then tie down the main cola two-three times until the other branches catch up. For instance if I wanted 15-17 tops I would pull the main cola down when the plant had 10 nodes as I would likely trim 2-3 bottom sets. I sometimes have to tuck rogue branches under other branches for a few days as well. But it's the easiest way I've tried and it comes out remarkable well considering.
