hahaI thought you're building a grow cabinet, but I can see you're about a hypersonic wind tunnel..
my ikea dresser have sligtly wider doors so i cut some thin strips of velcro/tape i had lying around, now the seal isnt perfect by any stretch, but its an improvment, helps with ligth leaks tooEdit: Nixed this cab
Here is the cab I'm considering buying for this project. Maybe one big piece of reflective insulation inbetween the doors and the rest of the cab? I've pretty much got the inside air flow figured out I just need help figuring light proofing the door.
