I'm assuming by your username that this is going to be a closet grow, therefore being indoors. I can generally say that you should do ScrOG or some other method to maximize light penetration and exposure for the full plant(s). What might help is listing the specifics of your grow, such as the lights, room size, and what growing system/medium you're using.
What also might help is searching next time. Have a good one :thumbsup:
