Hi all, I'm new here and am having a really hard time finding a thermostat for my incubator... I made it out of a wine cooler, and had a water heater thermostat in it. The problem is that when the room temperature went down/up so did the inside temp... I've tried calling petsmart/petco and any reptile stores around, and no one carries them? Wondering what kind of thermostat I can use to help keep the temperature stable? I appriciate any help, thanks!
