I am new to the BP world. My setup has a high temperature of 90F and a cool area of 70F. This is the temperature on top of the substrate. My BP stays in the cool area hide and rarely goes to the warm area. My humidity is 55% and over all temperature is 80 towards the top. Should I worry about him staying in the lower temperature area. I get the readings on top up the substrate with a temperature gun.

any advice or piece of mind would be helpful.
thanks,
Cody
