i have done lst you take string or they sell rubber coated wire that is made for training plants. You pick a spot a few nodes up on your plant and then you wrap the string or wire around the plant and tie it to something either a stake or a whole in your pot or whatever. and you bend the plant that way. you wait and let the plant grow for a bit and then you can go a few nodes higher and tie it off and then bend the other way never taking out the first tie off you made. it makes your plant kinda like a z instead of staright up and down. remember to leave a bit of room in your knots or your loops you make around the plant, the place that you tied it off will get bigger so you dont wanna strangle your baby lol
