Original writing on the climate science of cigar storage. Vapor pressure, dew-point margins, real sensor data, and the rituals of keeping a humidor honest.
How to light a cigar without ruining it: equipment, technique, and the storage problem people miss
Most 'this cigar burns terribly' frustration has nothing to do with how you held the lighter. It's the wrapper holding too much water, or too little, or a moisture gradient you can't see. Flame, foot, and the box the cigar came out of.
By Roger Govee or Shelly H&T for humidor monitoring: how I split mine
The two sensor families The Cabinet supports. Both work great. Here's why we picked these two, what each does well, and how I run them across four humidors.
By Finn Boveda vs distilled water vs propylene glycol: a data-driven comparison
Three classic ways to control humidor humidity. Two are still common; one is fading; one is controversial. Compared on stability, cost, maintenance, and risk.
By Finn How to season a new humidor (and how a sensor proves it's actually done)
Most seasoning guides oversimplify a process that takes the cedar lining 7–14 days to actually finish. With a sensor you can see when the wood has reached equilibrium. Without one, you're guessing.
By Finn Dew-point margin: the metric that prevents humidor mold
Mold doesn't grow because RH is wrong. It grows because something inside the humidor crossed the dew point. Here's the second number every humidor sensor should report.
By Roger What humidity should a humidor be? An argument for 65
70% RH became the cigar-world default through historical accident, not science. Here's why I run 65, the conditions where you should stay higher, and how to settle on your own number.
By Roger What VPD means for your cigars (and why your hygrometer is lying about it)
Vapor Pressure Deficit explains why a humidor at 70% RH can still dry your cigars. The science, the math, and the fix.
