Tom hope all is well, going thru some really cold weather . I have my adult Indian stars in a 8 ft enclosure in my garage. I have 2 che’s and 2 heat lamps and a UV bulb. When it gets really cold I also have a heating unit in the garage. I want to get the heating and lighting correct once and for all. What should the heating temp be on both sides and should I be using a thermostat to keep the temp consistent ?
