Yeah I got thermostat, but not with a probe.

So.. I'm looking on Reptile Basics Inc... and looking at the rack system, it says it already comes with heat, could I add to it if it's not like enough, and would my baby be able to escape. Because what I'll do is save up and get this set-up, since I guess I could still use the retro bark and decorate it accordingly and be able to have room for two more when the time comes! Since I'm looking for 'em for after christmas <3.
