Help Convert Closet to (small) Walk In Humidor

[CentralTimeSmoke]

I don't see why there's concern over dampness--this is a humidor, not a greenhouse. 65% humidity shouldn't cause any kind of mold/dampness issue with drywall, unless your active humidifier isn't properly set up and it's all going to one spot on the wall. This is how I gauge whether I can buy and immediately smoke from a B&M...if it feels like Florida when I walk in, it's too humid and will need rest. A correctly humidified humidor shouldn't really feel like anything when you walk in.

Just think about your coolidors or humidors--do you have any issues with mold or mildew? They're just tiny versions of a room. If you're wanting some Spanish cedar to help with humidity retention, I've seen people use cigar box lids in a mosaic-type fashion on the back of a cabinet humidor and it looked great. Most B&Ms will give them to you for free, or look out for estate sales/Craigslist.

IMO, your most pressing concern is what kind of door to install. I agree that you should leave it in the hands of a pro, and glass would look great. I would try to get it as air-tight as possible. I think the idea of outside airflow is a bit overstated. I've used nothing but air-tight coolidors for years now, and some I won't open for a month of two. Never had any issues whatsoever. I would install a small fan at the bottom and have it kick on every other hour just to keep the humidity constant throughout, but that's it.
