How many CHEs to use...
I KNOW I have seen this on here before, but my search skills are seriously failing me tonight. :/
Anyways- I have the one level ferret nation habitat. I plan to use the ceramic heat emitters for the cage, how many do I need? One or two? Also- what is the difference between a rheostat and a thermostat? Obv. I know what a thermostat is, but I don't really understand a rheostat. What is the difference, should I get both?
