Here are some pics of my situation. What does GC do with their light leaks in a cabinet like this? Complementary shot of the spinach I am growing.
reflective duct tape.. its silver with red lettering... 18 a role or so at home depot and for the doors use some of that window foam... just measure the gap and get something slightly larger... like five bucks... and theirs lots of sizes for the front lip between the doors.... tape up a piece of cardboard with the reflective duct tape all to one door... so it locks the light in or purchase some of that attic insulation and make a huge flap in front of the doors like the other guy did... either will work
reflective duct works well for holes but for door seams I'd go with 1 of 2 methods. Weather stripping works like a fucking charm its what I used on my dresser stealth grow cab but with 2 doors liek that it could be tricky. Other solution is caulk plus vasoline. You vasoline the parts you dont want that shit to stick to and then caulk up the leaks.fucking messy as hell though I bet, never seen any one actually do that just heard about it being possible.
