Substrate and UTH?

[Avalon]

Yes. I use an accurate thermostat where the hot side is.

And I meant "enough" as in to where the heat pad won't by chance heat up too much.

Accirite doesnt make a thermostat, they make THERMOMETERS.
You need to use that thermometer to measure the temperature under the substrate.
Substrate is not meant to regulate how hot an area gets.
Only a dimmer or thermostat can regulate your heat source.
Please refer to my crayola I posted earlier.

I have everything settled... I have a thermometer to accurately measure the temperature from directly where the heat pad is. I'm sorry if I confused you or something because I kept on confusing myself somehow on the words thermostat and thermometer. The hot side is at 90 degrees and the cold side is 79. I use probes and gauges but I mostly use the gauges because their more suiting for me.
