Just came to mind... I read about a Scrog method, where you have a chicken wire type screen, and you continue to tuck everything underneath the screen even once it starts flowering. The idea was to get the screen to be full of buds, instead of just the tops popping out individually, like in a typical like I'm doing.

With that way, you can put that Screen about 2 inches from those lights, and keep tucking the plant back underneath... just an idea.
