Ok, here is how I look at it:
Relative Humidity is called that because it is the amount of water vapor relative to the temperature. The amount of water vapor is irrelevant to our cigars but plays a factor in determining %RH...
Think of it this way, when it is 100 degrees out how does your body react say:
in FL where the %RH is 90%, you sweat your ass off because the air cannot absorb the moisture your body is putting out
in AZ where the %RH is say 50%, you sweat but are dry because the air absorbs the moisture from you skin.
The point is, it is all about balance. %RH Air > cigars = cigars absorb moisture from the air, %RH Air < cigars, air absorbs moisture from the cigars. The temperature at which this happens is irrelevant. All the details are just details to describe %RH and we do not care.
If you like your cigars at 65% keep it there regardless of the temp. The temp come into play with aging AfAIK...
Thats it for now, i am probably completely confusing people by now...
