I LST and SCROG them. I KNOW for a FACT I was the first to Scrog "Think Different" when everyone was trying to feed me that shit that auto's couldn't be trained. Blew that shit out of the water, and got a spot on Dutch Passion's Web Site.
Scrog works better with longer growing, larger, and higher yielding auto's. LST works on everything but the smallest genetics to increase yield in auto's. If nothing else, you're opening the plant, and giving more of the plant intense light which little airy buds underneath really respond to.
