Having trouble getting the temps up in my 35 gallon. Its currently 75°.
I've got a 75 watt bulb, a exo-terra desert UTH with coco-husk substrates (Just put in), and a Plexiglas lid. This was all setup like 3-4 hours ago.

Should I just wait it out? Substrate is still cold, so I'm guessing that I need to wait till more of the water evaporates. (75% humidity)
