I have 2 regular females in sterlite containers. On a ranco thermostat with the ranco 11 inch flexwatt set to 94 on the warm side. But the cool side i cant get higher then 74 degrees with a 1500 watt oil filled heater in my basement. Would adding a thermostat set to 85 be a solution to this problum? My 1100 gram female hasent ate in 2 1/2 months due to this prob.
