Fan placement for optimal air circulation

[N2Advnture]

Eric,

The reason for the higher RH at the top of your humidor is because humid air is lighter (less dense really) than dry air.

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
