I'll just repost my response here to merge the two...

Well it's going to be hard to tell if you need two. It will depend on where in your room you cage is kept, how much sun it gets and a multitude of other factors. In short, you just won't know if you'll need two thermostats until you set up your warm side and measure temps. You may not need a second one if you can insulate your cage. As for those Repti Temp 500R, is that the thermometer or thermostat? I wouldn't recommend either. A simple accurite indoor/outdoor thermometer is cheaper, and I definitely would use one of their thermostats. I prefer the more expensive HerpStat, Helix or even the Ranco.

I'd say set up the enclosure with one thermostat and see if you can manage the temps without a second one. If you can't, then I'd go for the second one.

I hope that is some help.
