Have you ever been to a cigar store? some of the humidors I have been in are 100 sq. ft. refrigerators. Of course the ideal temperature is about 55 f to 65 f. and do try to keep the humidity to ideal condition and monitor it with a humidity gauge.
The reason for the low temperature is to eliminate the possibility of tobacco beetles hatching (thanks for mentioning the temp. thing). But I agree, the problem with a refrigerator is that they suck out the moisture. The glass jars are a great idea. Remember to only use distilled water though in the humidifying device. Cheers.
