I would suggest adding two fans on the top of the humidor to push the RH down. I think you would have to experiment with the timer to get it down right as not to push too much down too quickly.

I hope this helps

I had the same problem with my Aristocrat plus 48. Typically 6-8 % higher at the bottom. Mark, you are correct that humid air is lighter, but Eric's problem is that the air is not rising. When I called Bob Staebell he suggested to leave more room (not overfilling the shelves) to allow for better circulation. So, I moved some boxes around and left some room on the sides and rear of the shelves and it did make a difference. Not sure if this will help you out Eric, but it did for me.
