So I am spending a hell of lot of free time lately looking at snakes, everything to do with reptiles, Brian videos, blah blah blah, the stereotypical reptile lover starter pack. But then I got curious; I often see racks that people have set out with all the RUBs and heatmats, but they don't really go into detail about the thermostats.

I know that some people have a room dedicated solely to heating reptiles, but for those who don't, I imagine the heat source has to be monitered at multiple points. How does that work out? Are you supposed to use a single thermostat for each RUB, because I imagine that can get pricey pretty quickly. Or is there some other mysterious way of monitering a larger amount of reptiles on a thermostat that I don't know about?
