yeah man i hear ya, only real way to figure shit out is doing it...I certainly dont know everything, very little if you consider how much there is to actually know about this great hobby. "LST" is short for "low stress training" it works great if you have limited space to work with, or wanna get lots of tops (least i think) currently I LST all my plants cause i dont want anything goin past 30 in really...only had one real run at LST so far from clone to flowering plants and it turned out amazing!!! all you really do is tie the plant down, once you feel its old enough which 3-4 weeks after seed i usually start to pull on them, instead of having a tall straight plant in the end you will have more of a bush! Also, when cloning I belive its best to you straight up distilled water, personally thats all I use is distilled water nothing else!!! Still havent gotten cloning completely down but have successfully cloned 2 strains, and also cloned those clones, altogether rooted 6, still trying to figure out best way for me to achieve 100percent success!
