It's in the trimming part....What it is, is you cut the main stem just above the node
and you get 2 offshoots as opposed to 1...2 tops...YAY FAQ has it there I read it..
look in trimming & pruning.....
it splits the main stock so you get 2 kolas so you get 2 flowers rather then one.
you do not have to do this.
many growers trim the bottom off and only allow the main flower to bud.
