Humidifier Problems.

[dijit]

A few weeks ago my humidifier started going haywire. I have the Hydra it is about 5 years old so probably time to replace it anyway. The trouble started about a month ago the reading on the humidifier was set to 72% but all of a sudden my humidity was down to about 65%. I had to turn the humidity all the way to 85% to get to 70%. So imagine my distress when I see mild growing on my most prized cigars and the new humistat says the humidity is 81%. I have cleaned the mold off and only see slight signs of over humidification such as cracks or splits or even separating seams. My question is this even after a week the Humidity level in the humidor after removing all himidifiers is still 78% and I am starting to worry about my NC cigars. I have moved all the better sticks to my old humi but dont have room to fit everything. Any hints on getting the humidity under control would be appreciated.
