Thank you for your response! That helps a lot in planning this out. What if I were to try and have the RHP create the hotspot instead of using both? Because the RHP needs a separate thermostat, I would need to buy more thermostats AND the RHPs...that's a whole lot of money at once, I really can't spend too much. In that case, would the 80 watt be better as to not be one massive hot spot or are RHPs like heat tape and some spots are warmer than others (namely the center)? Or would the 120 provide the hot spot but not be overwhelming by heating most the cage too much? Thank you again for your help, as you can see I'm totally new to RHPs and I want to make sure I don't overheat my snake or take away her gradient (even if she usually lazes in the cool side anyway). ;o;
