Xheck out this video on Supercropping. It is a painful process the first time, kind if like a woman giving birth the first time, then deciding to do it again. The benefits far outweigh the Cringe.
I remember reading a cannabis growing guide written in the 70s that described supercropping in detail as well as different topping and scrogging methods. It's just funny how these things come back in a circle and everything old is new again as each new generation of growers discover the old timer growing methods. Supercropping is a great way to strengthen your stems all throughout veg.
