I've used non-electrical humidors and and live in San Jose, California (northern california) area and recently picked up some hygrometers to really see what's happening in my humidors.

Never thought much about the 70/70 rule and recently also started trying out Boveda and my humidors at around 66-70% humidity, but the temperature has been at 80F for the last few weeks in my place. Looking at historical data online it's typically hit over 80F at least 6 months out of the year. I've never noticed a beetle infestation yet! But have read that anything over 75F is not great.

Do others in the area use electrical to keep things cooler? Or stick with non-electrical and disregard the temperature for the area?
