Question about new tub set up

[Vypyrz]

The picture of Vypyrz set up is the same way mine is set up I need to get some pics. I also have to keep the thermostat set at 92. It keeps the cooler side of the tub at a steady 78.The only thing I have different is that I use paper towels. When I used the aspen my humidity was going almost to 90%. As soon as I took it out it went to 74%

I use oscillating fans for air circulation to help keep my humidity stable in the tubs. I basically have them on low speed and setting about 5-6 feet from the tubs.
