Hello,

I've set up my terrarium for my new snake, but I can't seem to get my UTHs to heat up even with their thermostats cranked. I
m only gettin 77 to 78 degrees or so on the top of the substrate.

I have about 2" of reptibark over paper towels as my substrate. I realize that this is probably too much substrate, but I'm not sure how much I should have.

Also I have not covered my wire mesh top yet, so humidity is low. Will this affect the substrate temps?

I'm just dialing in the thermostats at the moment, I don't have the snake yet so I have some time to fiddle around.
