SO..... I set up my 6qt tubs let temp stabilize for about 9 hours with a dimmer then put my new babies inside.

as soon as my cinnamon went into her warm hide she laid on the probe and the temp reading instantly started dropping.

so my question is what do I do? I was planning on adding a thermostat this weekend, but if this was to happen with a thermostat attached it would instantly kick on and bake my snakes..... wouldn't it?
