ball up a rag or t-shirt and stick in hole
tinytoon Reviewed by tinytoon on . Help on light leak (cords going through wall) So on my grow closet I am running my water hoses and light cords through a 2 inch hole. Any suggestions on how to block that up so there is no light leak? Tried using some thick black paper and duct tape but that still has some leakage. Any help would be great.. Thanks Rating: 5
