I know I am starting to be a pain in the butt, but I want to build a rack so I can get into the game eventually, and i need to know what the difference is between a thermostat and a rheostat.
Are they interchangable?
Do they do the same thing?
Please forgive my ignorance

A thermostat allows you to set a particular temp and a rheostat is just a dimmer switch.
A thermostat is the way to go for breeding Balls.
