You're right, and I meant to write thermostat! I had no idea that there were relatively affordable rack systems out there that were also already prewired with heat tape/ Although a little more expensive than DIY, there is the convenience factor of having it already pre-made for sure! Thanks! Seems like Animal Plastics and Reptile Basics are the way to go. The divider option with the RB racks looks like a great feature that adds a little versatility.
