How to light proof a closet

My grow closet doesn't have a door on it and i was wondering how i could close the light in. Would hanging a comforter black it out? What can i put up?

Im thinking of making a door out of cardboard pads, would they be light proof

My soon to be grow room doesn't have a door but with my super wood cutting skills I will make my own

Get some thick black plastic and create a curtain door. Check for leaks when your lights are on.

You can use velcro, and overlap the edges.

purchase black/white poly - it's cheap and works very well and will take care of your issue

^^^^like @harris hawk was saying. Then you can keep it all reflective and stuff

Can zippers be installed on these or would a tarp be needed? It would be nice to have easy access to the light proof closet.

A combination of adhesive velcro strips and BW poly would be awesome.

It's double sided. One side is black and the other is white so that you can reflect on one side and block light out with the black side.

They handle "zippers"

I have an exhaust from the closet but am currently using passive intake from the big gaps around the current doors. If I seal up with poly wont I have to put in a vent? Can the vent be in the poly and be light tight-ish?

I need to revive this thread because i need to lightproof another bedroom closet and i cant find the wormsway site. This will be used for a 100% legit garden. The main reason for it is that hps lights are a more affordable way of heating a mobile home. So i need something that lets heat out, but not light, since i will be sleeping in the same room.
