i made an incubator out of an old mini fridge but i have been having some trouble regulating the temp&humidity inside of it. i have been trying all sorts of lightbulbs but none of them are working out and the humidity is either too high or too low. i was wondering what i could use besides a lightbulb and some wet cloths to regulate heat&humidity. would a reptile terrarium heater turn off once it got to the heat it was set to? my setup is basically a just a mini fridge with a bunch of holes drilled in it for ventilation and to put wires through for plugs also also anyone know how to make an automatic egg turner?
