And when you add MYLAR to the floors and walls that same intensely directed light gets bounced back up to the leaves and guess what? More and better bud but stick with CFL's and bugglegum and the snakeoil salesman selling the latest and greatest in CFL growing....hhahahahhahahhaa....
AHAAAHAHHAHAHAHAHAHAHAHA!!! hahahahahhaha OH god. Now I really know not to listen to a word you say. Dont be a stupid ass and TRY to reflect light back up at your leaves. Are you retarded? They cant soak light from the underside of their leaves. The most you would do is burn your plants (esp with HID) Hawhawhaw. Ah I feel better about myself now.
