Marijuana auto's without topping

A question from a fellow grower:

With auto no topping? Does it just form one big cola? Does it do well with SCROG or should I just let it grow straight up?

Generally whenever not topped any MMJ plant will have a dominant Kola and about 4 secondary kolas. If you top or supercrop, then you will produce more and much larger secondary kolas. Toppin will create several that id the whole plant gets good light all the way around, through rotation or reflection, you can produce several larger kolas.
