how do cigar humidors work
The purpose of the humidor is to keep your cigars at peak freshness. Ideally, conditions for your sticks should be at about roughly 70% relative humidity and 70 degrees F. In your humidor, you will have a humidification system in which you will put the solution - usually 1:1 distilled water and Propylene Glycol. The PG acts as an agent that keeps the Relative Humidity inside your humidor balanced. A hygrometer will measure the RH so you can be assured you are at the correct level.
