Help. i think one has HERMIED

I would try to find a way to get intake back to bottom. You would prefer to bring cooler air in the bottom and exhaust warmer air out the top. If you need to, grab a few of 90 degree duct fittings and paint the inside flat black. Then arrange so that light can’t pass through



Thank you for the suggestion. I will try to find those vents at My local Lowes.

What kind of ducting are you using ?
