Currently, I don’t use either. I have a roof de-icing cable from a big box store and run the single length cable along 1/3 of the underside of the tubs and loop back to the backside for radiant heat ... all on a single thermostat. Am I going to get excommunicated? Temps are all fine. I also use digital hygrometers and thermometers in each tub to make sure each one is good ... maybe overkill but I prefer to know min/max for both temps and humidity for each tub and just add a bigger water dish to increase humidity for those going into shed.
