Ya boomwhomp has a point, topping isnt succesful with all breeds but its just trial and error you could come out with a much bigger yeild. See how flexible that stem is and tie a thin nylon string around it tie the other end to a coathanger or spike and stick it in the ground then bend her about 1- 2 inches over every day. Training is the shit i have my plants growing across the ground like vines, and you usually get a shitload more yeild....
