Ok... So I have a 100ct desktop humidor the wife got me last year. This thing has been working perfectly up until about 2 weeks ago. I keep 2 jars of beads and one 69 boveda pack in it and it stayed at 67% constantly until recently. It's now been reading 62-63% for the last 2 weeks. The beads have enough DW and the boveda is not dry. I have a zederkoff hygrometer in there, I thought it might be going out, so I switched it with the one in my mini fridgeadoor which always stays at 69.... After a couple days I checked it out and they were the same again. The one in the fridge was 69 and the one in the humidor was back down to 63. Maybe this is a result from running the heating in my house? Maybe I need to add more humidity to it? What do you guys think?
