Cigar Tube Humidifier

This compact humidifying element will occupy minimal space in your humidor, allowing you to fill your humidor with more important stuff.

** FINAL STEP UPDATED **

To make your own compact humidifying element, you will need the following:
-- propylene glycol crystals
(I get mine from Cigars International, but other online cigar stores stock them)
-- an empty aluminum cigar tube
-- sandpaper
-- 1/8 " drill bit and drill
-- center punch

I sanded all of the paint off of the cigar tube for aesthetic purposes, but this step is optional.

Mark the tube with the punch in 1/4" intervals along a straight line, then drill.

I squished the rather malleable tube in a couple places while I was handling it, so I used a smaller cigar tube to pop out the dents. After you are satisfied with the tube's condition, fill it with propylene glycol gel.

Cap the tube and set it in your humidor. Admire the vast new space made available to you for cigar storage.

** UPDATE **

After a little more than a month of use, I determined that my humidifier was registering consistently low hygrometer readings, despite rehydrating the gel a few times.

To solve this, I drilled a large number of additional holes (on all sides) to allow for better air circulation and evaporation. It works -- keeps my humidor interior within the requisite 66 - 79% humidity zone.

Below is the finished product.
