Light

I am currently have a set up going in my closet. It has a regular size door with a deadbolt. I was wondering if there was any way to cover the light so you dont see flourescent light thru the gap between the door and the jam. Could i hang a curtain from the inside??

Im not sure exactly what your setup is like but this works good to seal off light.

You can get it elsewhere I just use them.

You could do what you threw out there. You could also use duct or electrical tape. I stapled cardboard pieces to the inside of my grow room in the entrance door.

Black n white poly's good its cheap and easy to keep clean.

Curtain is bad! full of nasty spores n stuff.

I have the same problem and im going to cut garbage bags and staple them inside on the entrance

Yeah, i think i am just gonna get some of that poly and staple it on the inside of the door jam and hang it down.
