Duct tape that sucker in!!!

And you are being too impatient. It takes time for the humidor to reach stability (sometimes 4 - 6 weeks).

Wipe down the insides with distilled water - put your beads in there - wait 2-3 days - fill the humi with cigars. Just keep an eye that the level doesn't fall below 60%.

Also - you need to do the salt test on your new hygometer. Out of the box, analog hygrometers tend not to be very accurate and need adjustment. If you have a digital hygrometer you're much better off!

Next question - how are the seals? On a humi like that, I tend to think they're not very tight.
