they need belly heat to properly digest food and a way to thermoregulate their body temps, so as long as you have a cage floor temp of 90-92 hot and room temp cool you are doing fine. Well that is as long as the col is not as high as the high of coarse.
It does and doesn't to a technical point. What do you use to heat the cage and what is controling the heat source? I use UTH's controled by rheostats. I have noticed that the cage twmp will fluctuate along with air temps. In the summer when the air is warm I have to turn down the rheostat. When it gets cool in the winter i have to turn up the rheostat. This shouldn't occur if I was using a thermostat. See what I mean by it does and doesn't.
I see I dont use a reoststat or a thermostat i just make sure the bottom of the cage is 90 and the air is about 90. When winter comes around the corner i use a heat lamp and in the summer i use a low wattage heat lamp. Can a reostat make the UTH hotter than it is when it is plugged into the wall??
You didn't really answer my question of: "What do you use to heat the cage and what is controling the heat source?"
Also what is the substrate that you are using?
If you are using a UTH and are not using a t-stat or r-stat to control it. Then the UTH is heating up to the hottest temp that it can. I use paper towels for substrate. As I mentioned before, in the winter I have to up the r-stat to maintain a floor temp of 90 degrees. Where as in the summer I have to turn down the r-stat to stay at 90. If I didn't use an r-stat to control the UTH it would heat the bottom well over 100 degrees.
If you are just using lights as a heat source, then you have to make sure the cage can properly ventilate.
