Put your thermostat probe right on floor under the rhp and set to 90 and wait, thats exactly how I have it and everything is perfect. I'm just testing right now and I have substrate. I think substrate may hold heat better then the cage itself but 80 seems rather low even without substrate. But if you put your probe on cool side then 80 would be good. But 80 for hot spot seems low. Just doesn't make sense to me. If you have probe hanging in air you will need to set the thermostat temp higher. Idk what boaphile uses for air flow but if there's a screen or vent completely cover it with PVC or something bc it will let a lot of heat out. I will also say that with my ve-300 it took about an hr or a little longer to get to temp, the set point alarm went off once and then when I hit the enter button twice it started heating again and made it to the set point where its sitting at now.
