i actualy think the LST is great. the plants are seeming to love it and its really not slowing the growth at all. the bottoms have just exploded into branches and the tops just come right back withen there 6 hours of darkness. seems like when i tie them back down right before i go to bed, they look all deformed, but when i go check them in the morning, a few hours after the lights come on, they all just standing right back up. its working great.
