The proper humidity levels will stop mold from developing in conditions that have too much moisture in the air and will stop walls and floors from cracking from a lack of humidity. At the same time, every humidor needs its own hygrometer in order to preserve the integrity of the cigars to ensure that every cigar tastes its best once it’s lit up.
