My mid point air temp is only getting to 75-77 and the heat pad still partially covers this area. The air temp in the hide is around 88. Thats why i was thinking of running flexwatt around the sides and controlling the temp using a thermostat. I would not actually attach the flexwatt to the tub but run it along the inside of the rack. Do you think this wil work? I'm not sure what else to do.
