So i have a 32qt sterlite tub. I have UTH on just over half of the tub, the thermometer reads about 120 on the plastic and about 95 on the surface of the aspen (thin layer). The cool side is reading 77. The humidity is around 50% (though i will raise it when i put the snake in). So i need to warm up the cold side, while cooling down the hot side. I have a dimmer switch on the UTH. any suggestions from tub veterans?? I would like to move my snake in whenever i get this thing figured out.

Thanks for the help!
