I thought that, but it didn't sound right to me.

Edit to add: I looked it up, you are correct.

The amount of water vapor in the air also effects the density. Water vapor is a relatively light gas when compared to diatomic Oxygen and diatomic Nitrogen. Thus, when water vapor increases, the amount of Oxygen and Nitrogen decrease per unit volume and thus density decreases because mass is decreasing.

Consistent Rh from top to bottom is not as important as one might think. What is important is that your cigars smoke as you like them. Your not smoking air, take some readings in various boxes in different places. The Rh inside your boxes is whats important. If your top to bottom Rh varies by less than 10% you should be fine. I rarely even look at my hygrometers any more, one Vino and a couple of coolers dont even have working hygrometers. I only use 65% Heartfelt beads and things have been fine for 4 years.
