Sorry I'm an ultra newbie u might say and one question I have is do the holes you make for intaking air have to be covered to prevent light leaks as well?
yes, I'm new too but I have read that useing PVC pipe painted black on the inside with a few turns helps. I imagine a black dryer hose would work too..just my 2 cents. Anyone else? Edit: I have read that ANY light leaks can completely screw the grow process up, so make sure no light is getting in. Crawl inside and close the door..or pay a midget to do it if you have to.
