So I finished setting up my crestie terrarium but having trouble getting it up to daytime temp. The ambient temp in the room and tank is about 68 degrees +/-1 so I'm fine at night. This is a live planted 55 gal tank with about 4" of substrate. I have tried using an infrared heat light but that only gets it to about 72 but it drops the humidity drastically. I just picked up a ceramic infrared heater but I'm afraid this will do the same thing. I am thinking of ordering a heat mat and hydrofarm thermostat. Would this work better for getting the tank up to daytime temp? And if so where do I mount the probe? At the surface of the substrate? I have a drainage layer of about 1" of rock then about 3" of abgs so would the UTH be able to heat it thoroughly?
