I am building a live rain forest for my ball, and I am stuck on getting either an Herpstat 4 or an Herpstat ND.
At a minimum I want to be able to control the under mount pad and my basking light with separate temps. with night drops to fully emulate the wild.
I can monitor humidity manually using a gauge and UV lighting on a cheep timer.
Would the Herpstat ND allow me to control both heat sources with different temps or should I invest in the Herpstat 4 and control everything?
