UTH Temps

[The Serpent Merchant]

I'm using a temp gun that would count aas an accurate thermometer. Do you think if I give the substrate a couple of days it would warm up to 90 or so? My BP isn't in the tank yet so I have a couple days to mess with everything.

A temp gun can't measure the temperature of the glass under the substrate. For that you need a probed thermometer

I doubt that the wood will warm up too much over time. As i said before it is the air pockets between the wood that is blocking the heat.
