A. It's generally a good idea to keep your humidor in the coolest spot in the house and avoid any direct sun or lamp light. This will help a lot.

High temps and humidity can cause beetle larvae to hatch, which is the most important reason you want to keep the temperature down. Under these same conditions, you may also see "plume" or "bloom" appearring on the wrappers of some of your cigars. If this happens, note that it's a harmless, white powdery substance that can easily be wiped off with your finger.

If you can't get the temp closer to 70-degrees, then try to lower your humidity to help balance the system. Most importantly, make sure you check your cigars daily until you have the situation under control.
