Where do you set up the probe for RHP? I've been following along this post and you've all provided excellent insights. I've been saving to upgrade to the Herpstat 4 up from my vivarium electronics since I need 3 inputs (one for UTH heat tape and one for each RHP) as I have a T8 with a divider for 2 BPs and want to put an RHP on each side. There is a spot for the probe under the T8 so you can set up your UTH easily with a thermostat but where to put the probe to actively control RHP power is what I am trying to figure out.
