Should i do LST or not ? Or maybe LST one Plant, let one grow natural ?

its worth letting plants grow untrained in a sog grow. going 12/12 from the start with photoperiods. for letting a plant grow untrained to be worthwhile tho you should double or triple the plant count. you should use smaller pots and fill that space wall to wall. if you want to try it out do it but really training will improve yields in the end if the plant count is the same.
