how do you top plants when growing them and when do you top them?? and also how do you train a plant like a sativa to grow like an indica? and also when do you start the training process??
you can top as early as you want almost if you want to keep em bushy. usually you top at a node where you want the two new tops to come out. use scissors if you can, but i usually pinch them off myself. i try to usually top the new tops and top em once more to get monster bushes. you'll get 8 tops if you top em 3 times.
