If you use a proper closed chamber made of 1/2 expanded pvc, and the room temp is in the high 60s or more, and you use LEDs for lighting, there shouldn't be much of an increase at all. You would definitely not need 235 watts in my scenario. You'd ned an 80 watt RHP on a thermostat the would shut it on and off as needed. And maybe a CHE or Heat lamp to make a warm side. Or another RHP set on another thermostat.
