Pulse proportional thermostat with the capacity to drop the temperature at night if attached to a timer. The function of this thermostat is the same as the standard Pulse proportional thermostat but with the added facility of a night time temperature drop facility. With many species it is important to give them a cycle of warm day time temperatures and cool night temperatures. Many species would experience this in their natural environment.
In order to sucessfully keep reptiles in captivity you need to provide the correct thermal gradient for the species kept, in order for it to thrive. Without a thermostat you have no control over the thermal gradient within your vivarium which will fluctuate with the ambient temparature, depending on the time of year.
We therfore always recommend the use of thermostats.
