labifleanswered grow question 6y ago Hey gardener! I'm not a pro with autos, but if I'm not mistaken, you can practice LST and topping on all plants that branch out, and nothing beats mixing the two together, because LST keeps the plant low and topping makes it bushy. However, you need to wait for a certain size to do it and enjoy that bushy aspect, because if you have 5 layers of leaves, you'll have 5 layers of branches. I'm saying 5 layers because I read that it's the right time to do a topping, but some say later. As I said, it depends on how many branches you want, and you'll have 2 per layer of leaves. Good luck, bella ciao!
