Ok so the Johnson control was set at 97 degrees to get 94 on the top of the glass inside the viv. Under the substrate.

Used a temp gun and shot under the warm hide. On top of the substrate and got around 86-88 degrees.

Is it safe to bump the thermostat up to a higher temp to get the substrate (reptibark). Up to the recommended 92-94?

Right now the glass is steady around 93-94. But the substrate is too cold. With the substrate at 93-94 the glass would have to be around 100 or so.

What would you guys and gals do?
