Re: temperature fluctuation
What is your heat source? How are you controlling it? How are you measuring it?
Generally, your hot side shouldn't fluctuate more that +or- 3 degrees
Re: temperature fluctuation
Temps should not fluctuate unless you're not using a controlling device, or have a rheostat instead of a thermostat. :)
EVERY snake enclosure needs a thermostat to control the heat. Without it, temps fluctuate at best and spike to over 100 at worst.
Let us know the rundown of your tank: heat source, how it's controlled, how you measure temps, substrate, etc. With that info, we can help you reduce fluctuations. :)
