Ambient Temperature vs. Belly Temp.

I have a 12" high setup and currently I am only using a heat mat on the hot side providing proper belly heat of 92 measured with a probe laying on the substrate. On the cool side I am using a CHE providing a belly heat of 82 measured as well with a probe on the top of the substrate.

Obviouly on the cool side I have provided an ambient temperature which increases from the bottom to top of the tank as approaching the heat source. However on the hot side no ambient temperatue is provided.

So is an ambient temperature on the hot side of the tank required? Should i place a heat source on the top of the tank as well? (and of course decrese the heat mat power to keep temp at 92 F)

ambient temperature is the surrounding air temperature so even though you are not actively trying to create an ambient temperature on your warm end there still is an ambient temperature there. you just have to measure it.;)

Sorry, should clear that up, I have it measured, what I was wondering is if I should keep it at anything specific? Right now it sits a little above the temperature of my house @ 72 F. But what your saying is their is no need for an ambient temp of anything specific as long as I am providing a belly heat?

If this is true could I not replace my CHE on the cool side with a belly heat @ 82 as this would surely help me with humidity?

no, im saying that the ambient temperature is the air temperature within the enclosure.

the ambient temperature of the entire enclosure should be around 82. the UTH on the warm end should provide belly heat of around 92. the UTH may raise the ambient temp on the warm end by a few degrees and that is fine as long as the cool end stays around 82.

maybe try moving your CHE over to the warm end and see if that corrects your temps.

hope this helps.

Perfect, thats what i was wondering, what is an appropriate ambient temp. Thnks!

an ambient temp of 80-82 is good but if it is a few degrees warmer on your warm end then that is fine.
