Reducing the flow of air through the walk-in retards this process. Some movement is necessary or the air stratifies, with warmer air near the ceiling and cooler air near the floor. Equally as important, the humidity will be higher near the humidifier than at a distance from it. The air in nooks and crannies also stagnates, with both temperature and humidity levels becoming unevenly distributed throughout the humidor. To distribute the air uniformly throughout the walk-in, simply place a fan on the floor to move it around.
Cigars are like delicate flowers.
No wind may actually whip through your humidor, but the faster the air flow, the faster your investment deteriorates. The manner in which you heat, cool and humidify your stock is important, too. We know the importance of avoiding wide swings in either. Common sense says don't play concentrated hot, cold, or moist air directly over your cigars. Gentle, diffuse air flow is necessary.
