I completely cleaned out the closet in preperation for installing the lights and in some of the nooks and crannies I found some patches of dark mold. It also smells a bit musty and mildewy down in the carpet. Does this put a nail in my dreams of growing in this closet? Is there something I can get that will erradicate the mold and not pose a danger to my plants? I know how insidious mold is so I was very bummed when I saw it. Any advice is greatly appreciated
