Okay - So I got my wineador set up a few months ago - Kitty Litter @ about 3.5 lbs in a 24 Bottle New Air.
After seasoning the cedar shelves, it dialed in to 62% rh. It was rock solid at between 62-63 with cigars for about a month. Then - I started noticing the middle would get to 66% while the top and bottom were staying at 62%. I have no fan, but with so much KL dispersed, I did not think it would matter.
Now for no good reason the whole thing is up to 66%. I did not add water or cigars to the wineador during this time... though I have been smoking quite a few. I'd guess I went from 150 sticks to around 100 over the last two months.
I live in a very dry region. 35% rh outside is high around here. 25% is common. So I am not sure where the extra humidity is coming from. Any ideas?
