first off you need to line the back side of the main doors to the closet . them kind of doors suck for a grow closet , to much humidity makes them swell wont want to work smooth, hard to keep light from getting out , way to many cracks...lol..im just talking shit cause I had the same ...lol I ripped them down before I bought a light, made the door way smaller and put a normal door on ....wish you luck
