Humidifier and cigar placement in a cigar humidor

Q. I have a 300+ cigar humidor that’s about 14″ deep. I’m wondering on humidifier placement. Does the moisture tend to stay at the same level as the humidifier or sink/rise in the humidor? There’s some ventilation between trays, but I’m wondering if I should put humidifiers on both the top and bottom?
Also, is there any benefit with having the cigars on end, or laying on their side in the humidor?

A. Moisture from the humidifier travels downwards due to the natural weight of water. That’s why most humidifiers are placed under the lid. However, when a top tray is involved a good way to ensure you get proper humidification below the top tray is to place a jar of humidity crystals (see photo) on the bottom. The evaporation from the jar mixed with the downward flow of air from the top should help give you a better overall RH (relative humidity).

Regarding the positioning of your cigars: Try to keep some space between the cigars for additional airflow. What side they’re lying on is not all that relevant. Often with a high capacity humidor, it helps to have a fan to maintain good air circulation. Based on the size of your humidor, a Cigar Oasis XL Plus would be a good solution. It’s worth the money if you feel the circulation is causing serious problems with your cigars.
