I have a rookie question. I have purchased this used humidor And I am having issues. I have one tube of humidification crystals on the top rack and an open jar of water on the bottom. The readings have been around 63-67% according to the digital read out. The issue: my cigars are still drying up. Is there anything I can do to stop this from happening short of buying a new one? I have seasoned the box twice and it is hold steady percentage wise, but the cigars seem to still get dry and crack. With that much water in the case I would think cracking shouldn't be a problem. The case is not in direct sunlight, and is in my office away from direct air circulation from the A/C. Temperature is around 70 degrees as well. Can any one help? Thanks!
