Dear noob, what are you growing that a little led light would make a diff, Please think about a little marijuanna plant out in the wilderness, does the lighting storm faze the plant???? Does the full moon faze the plant?? Youre little LED would be the least of worries on my list. People talk about distilled only water,,, no light leaks all bullshit. But I would watch out for bud rot with that a/c.
