I use 65% in my humidor , and 70s in my coolidor for my long term storage, seems to be working allright
I also ran across something on a cigar sight and wondered if anyone had any thoughts on it
Storing Cigars
Most Cigars smoked in the United States must be humidified and stored at a mild temperature. There seems to be a common approach to these two factors. Cigars should be stored at 70 degrees Fahrenheit and 70 percent humidity. Temperature and Humidity can be looked upon as inverses, that is if your Temperature is 72 F your humidity should be 68%. Try and keep these figures within 3 or 4 points on either side. Keep your cigars in a place that does not get any sun, the heat from a couple of hours of sun can do some strange things to your smokes. The most important factor is to keep things consistent.
