Hey guys!

So, i have the heat light on one side of the vivarium so that there are warm and cool spots in the vivarium.

I have a thermostat that controls the temperature by turning on or off the heat light once it goes higher or lower than the desired temperature i chose.

So, im not sure where i should put the probe that goes inside the vivarium that senses the temperature?
If i have the probe too close to the light, the light turns off and on frequently, around every 30 seconds.

The heat light is on the back corner, right hand side so should i put the probe in the back corner, left hand side?

Thanks everyone!!!
