Whites Tree Frog Lighting! Help please :)

Depends what wattage you have going now really. Incandescent lighting will add heat better than a florescent bulb.
What bulb type are you using now?

A under tank heap pad also adds some warmth and if placed on a side will make a warm side and a cooler side.

The lighting I have now is a 75watt night light (only on at night), and a Repti Glo 26 watt 2.0 UVB. And can a heating pad be put behind a Zoo Med Natural Tile Background? That is what will be on the sides of my cage. I don't think I can put the heating pad on the bottom of the tank because the tank will be on my carpet floor.
