wow holy shit. I found this out on my own and have been doing this and trust me it works great. I didn't even know there was a term for it. I thought it was just all considered "topping" My lastest girl has 6 mail colas and a lot of extra branch growth. I must share. Here is a recent picture of her after a flushing ( i accidentally burned her a bit, but sh'e better) I have to tie her up to water because all 6 cloas and other braches are very very heavy and they will snap otherwise. Enjoy
