Need help on how to run my future enclosures. Should i buy the herpstat 4?

So would i have to purchase a power strip for this and connect all the RHPs to it, then connect that to the herpstat?

Theoretically you can do that. As was said, that's assuming that all enclosures are the exact same, with the same heating sources, not in a stack, in a controlled environment, etc. I personally would just use all 4 outputs on the Herpstat 4. Much safer in the event that the stat or heating sources should fail in any way. What type of enclosures are you using?
