OH, I don't either! Got a SCH I bent over on herself, and have decided to lst most if not all six gals I got running...check out the progress (last 2, maybe three pages of current grow link in my sig...got about six main tops now and three to four still under the canopy...been tucking leaves to get light to them...think these are gonna really perform.
You don't want to try and top ANY auto as there is no time in veg room to recover before flip since they flip themselves...Yes to save space, ESP. height -wise (SCH is supposed to get up 6' or so if left alone) LST it! I Have just been pulling branches away from the others I have started (and tucking big leaves), not sure about bending anymore, but who knows?
