Got a low plant with nice even canopy utilizing LST and growing under CFL's. Should I allow bud sites to get a jump by allowing some vertical growth before switching to 12/12 light schedule? Been growing same strain for last three grows. First grow had crazy strech, second grow had zero strech. I'm getting close to starting flower and still trying to figure out why last grow didn't strech. First grow yielded 6 Oz and second grow only yielded 3 Oz so you can see why I'm trying to get more strech!
