i bend the branches every few hrs ....lol. is that not low stress training? i am thinking about tying some branches to the hole in the sides of the alien pots, but idk. they will be fine when the stretch. i will tie them if i need to when i need to. i do some work to them while they stretch to keep the tops even as possible when the time comes. now i just do a lot of bending and leaf tucking to get the secondary branches shooting upward as fast and as much as i can. i dont like them too tall. i like those bushes with even topps all over really tying her would help that , but not yet for me ant way
