Light Tight issues, cuboard grow

hey guys, i started a new grow room and the only problem i have is the light is peeping out the side of the doors. does anyone have some good ideas on how to fix this, right now i have a plastic sheet hanging on the inside but doesnt do anything. appreciate any help. thanks

Hey man I had a problem with lights leaking out of my iguana tank. I took some of that grey foam stuff on a roll and I doubled it up and thumb tacked it around edges. Worked great

yea they sell weather stripping at most hardware stores to seal windows or doors it does the trick well

One more vote for weather stripping....

aluminum foil

Duct tape.

weather stripping works, comes in a lot of different sizes, and is cheap!
