scrog question

Hey green thumbs,who can tell me if your suppose to top your plants during a scrog grow?

You can, depending on what you want to do with the plant. Topping makes it so that the plant doesn't have a main shoot that's laid over. You can top and train the new 2/4 main shoots in opposite directions. 2 tops will let you easily fill an oblong area, 4 tops will be easier for a round/square area. I like to LST a little bit before they hit the screen too, especially if they're clones
