Ive heard of ppl controlling entire rooms off a herp 4 with multiple full sized racks, incubators, hatchling racks and room temps. Probe extensions are also available.

A 350 dollar multiple output thermostat will pay for itself in its flexibility in no time. And depending on your projected size, may very well only ever need the one, with a possible back up

Yes but the heat sources controlled and the cages they heat need to be identical. You can't hook up a UTH and a heat lamp on the same channel and expect it to work right.
