light proofing the hole for power cords

[CheebaMonkey]

I have a 3" hole at the top of my grow box that I plan to use for power cords but I'm wondering what would be the best way to light proof the hole.

Dear CheebaMonkey,
I would use some window sealer foam to fill in the whole space then to make it look decent nicely cover it over with gorilla tape. Dont use crap tap most are not strong enough and will eventually start to peel back. One stop shop at home depot. p.s. paint over tape w/ flat white.

I used that dense foam pipe insulation. The stuff they wrap hot water pipes with. Even comes in a precut 90 degree elbow. Got it at Menards. No leaks in mine. Good luck Fred
