I am in the process of building a frigidor from an old wine cooler I have. I have seasoned the unit and brought the humidity up to 65% and the temp is holding between 60F – 66F. The problem I am having is that whenever the cooling system turns on the humidity drops to 45% and as soon as the unit turns off the humidity slowly comes back up. Is this normal? Will this harm my cigars? Is there a way to prevent this?
