1. Aromatic cedar is bad for cigars. If that's what's in there don't use this for cigar storage.
2. Have you always used distilled water in the credo? If not you could have some nasties growing in there. It' probably not a bad idea to replace your credos once in a while anyway. In any case, I would not use that credo anywhere near my stash.

Is this the only "humidor" you have? If so I could offer some options for storage that won't break the bank. If you're serious about smoking and having cigars, you really should get a better storage system worked out anyway.
