This is very bad idea. You need some the film is not transparent and sealent.

Very quickly

6 you asked for a scale.. 6 is how heat score I feel that is. Not totally fool proof. But it's not plurple so it's not as obvious.

Let me put it plainly... If I was grower or a Cop, I'd be like hey that bright light is unusually bright maybe he is growing pot. If I was the average person I might not put 2 and 2 together. Like hmm maybe he just likes bright light or is shooting porn ha ha. You could always try putting up sign saying I'm sorry about the lights but I need for them my "skin" therapy. I find the more you try to "hide" things sometimes the more obvious and strange it looks. Where as if something looks normal or like it's a casual thing people may not automatically assume it's a Grow op.
