How important is ambient temp?

I wouldn't like my ambient temps to be that low. One solution maybe to adjust your house thermostat if possible, also check your room to see if you have 2 AC vents or one, because you can close one to raise the ambient temperature a bit if you have two.

I taped the probe to the bottom of the plastic tub where the UTH is and under the paper towel, reading 87 now. I think I am going to need a separate UTH/thermostat for the other side. Thanks guys!
