Only thing I will add is that if you use HF beads....not all humidors are equal. I recently converted a mini fridge to use just for cc storage. Based on the size, I should have used 1.5lbs of beads. I bought 2 lbs of 60% beads to be on the safe side. With just a few mists of water the RH was up over 73%. Then I realized, there's no wood in there other than the cigar boxes so it doesn't need as much media. I now have 6, 62% boveda packs in there and no beads and humidity is holding steady at 63%. Once I get some wooden shelves for it and maybe some additional cedar to take up some space, I will probably attempt to use the beads again. Just a little FYI
