I just ordered a ReptiTemp 500R (I think that's what is called) thermostat from Zoo Med and it doesn't exactly have a day/night heat cycle. The photoperiod is natural, Flint is in a huge photography studio with sun lights all over. I just need to know just how important the actual temp difference is from day to night? Being in a large warehouse-like room, the temperature isn't very stable, and the day/night cycle on the thermostat relies on having it shut off at night, along with your high powered heater, leaving a lower wattage heater on during the night. I don't feel comfortable with that at all. Nighttime lows here get in the 40's, so I want all the heating and control devices operating 24/7. If it is vital I will certainly figure something out. Thanks!
