First top the plant when it gets to the height that you want. Then the lateral shoots will start growing faster. Trim the laterals after the 2nd node. These will creat 4 more laterals that will grow off that and so on and so on. If you have high potency plant the lateral shoots that you pinch off will rival the potency off the bud, especially after the plant is 60 days old plus. Doing it this way you'll have alot of bud sites but the buds will be smaller. This is what I do in a phototron that I use for my mothers. An almost never ending supply of clones.
