I have attached a 16w exo terra heat mat to the side of the terrarium, connected to a thermostat, but the heat mat doesn’t get hot enough and never reaches the temp I’ve set the thermostat to. I’ve tried with two different heat mats and without thermostat, to rule out anything broken. Why doesn’g the heat mat get hot enough? It just gets to 30c, which through the glass only creates 23c in the substrate. I want to reach 28c on the substrate.
How do you all heat your Pacmans at night?
