I have a variety of different sticks in there right now - about 50 cigars total. CAO Flatheads, Olivias, Victor Sinclairs, Montecristos, Royal Jamacians, etc. The last few I've smoked seem to be a harsher burn - could feel it in the back of my throat, which is why I'm concerned about the RH. I've been smoking cigars regularly for about a year now. The previous humidor I had was just a little 30 stick humidor and I kept it right at 68-70%.

Last night I put my digital hygrometer into a ziplock bag with one of the Boveda 72% packets and the hygrometer spiked right up to 73% so I know it's calibrated. I then took the hygrometer out of the bag and let it sit for awhile - it's about 40% RH in my house.

I think my main problem is that the plexiglass panels are NOT sealed in. The manufacturer used the same technique as how the backings of picture frames are - little nubs twist over the backing to hold it in place. It's just "sitting" in place.

I didn't realize that food grade sealant would be readily available at home depot / lowes so I'm going to head out there later today and try sealing the panels better to see if that works.

I did try the dollar bill test around the door and there was some good resistance all the way around so I guess the tongue/lip on the door is OK. It doesn't necessarily make a "whoosh" sound when it closes, but this is only my 2nd humidor and the first one didn't make that noise either.
