Can two RHPs share one VE thermostat?

Since I found out that you could plug in an extension cord into a herpstat from a rack, I'm wondering this.

I'd be using two RHP's for two GTP enclosures who need the same temps anyway. So I'm wondering if two RHP's can be plugged into an extension cord, and then that plugged into a VE-100? Any worries?

The two sets ups need to be exactly the same and the total wattage can't exceed the thermostats maximum wattage
