One more thing. I realize you feel your humidor is well-sealed, and it probably is. Just to be on the safe side, put your cigar humidor in a dark/black room, turn on a flashlight and place it in your humidor, then look to see if you can see any light. If you can, you have a seal problem, and that may be where your humidified air is escaping from the humidor. If the leak is significant enough you sometimes just have to say goodbye to that particular humidor. Just my thoughts...........
