Preface
How I maintain my humidors is through a variety of humidification devices.

I specifically try to maintain an average of 65% humidity at all times. Why, you may ask. Because I prefer a slightly drier cigar. 70% or higher humidity can cause the cigar to smoke hotter and can make the draw more difficult. I have personally found the 65% humidity level to be the most flavorful for myself.

I do not become concerned when the humidor drops to 60% humidity, since that means it is time to refresh the humidification devices, and the cigars are still humidified at about the 65% range.

Devices in My Humidors
I have the following devices in my humidors:

• An "oasis" electric fanned reservoir (6' cabinet)
• Blue HumiCare rectangular ovals (multiple devices)
• Tubes (multiple devices)
• Bowls of granular beads (multiple devices)
• Boveda humidity packs (multiple devices)

These are refreshed (or with Boveda, replaced) every 3 to 6 months, as needed. The "oasis" electric fanned reservoir requires more frequent refill due to it continuously "blowing" operation.

Continuous Supply
With Boveda humidity packs and with beads, these exude moisture at a relatively regular 69% to 72% humidity rate for long periods of time. The tubes seem to last the longest, often going a whole year on one refill.

Measuring Humidity
The analog dial hygrometers rarely read correctly, and while they can be "tuned" fairly easily, that necessity are far too frequent, so I tend to ignore the analog hygrometers.

Instead, I monitor the "oasis" fanned device which has a digital hygrometer display, and try to keep it reading at least 65%, but I don't worry about it dropping to 59%, other than to pull out the reservoir and refill it.

I have found this practice to be sufficient to achieve my average 65% humidity preference.
