I need some help. I have had my humidor for about a year and a half. It is about a 50 ct humidor. I usually have 5-10 cigars in it. I put distilled water into the humidifier disk every week or so and the humidometer always reads between 70-75. This all seems like everything should be fine, but if I let a cigar sit in the humidor for a few months it usually dries out and cracks and falls apart if I try and smoke it. I especially see this problem with cigars that are not in cellophane wrappers. Do you think the humidometer is not calibrated or am I doing something else wrong.
