Gets nippy fast, doesn't it? Lol. You're going to need to use heat lamps for day and night. Day time bulbs like basking lights to help heat the enclosures. Infrared heat bulbs at night. The UTH (heating pad) should be the constant heat source. You can buy lamps with a dimmer switch so you can adjust the heat and amount of light coming from the lamp. I use that type. Its good for keeping the enclosures exactly calibrated the way you want. I use 50 watt bulbs. If you are using a plastic pet carrier (I can't remember which enclosure you said you have, sorry) then it's better to suspend the light above the tank so it isn't directly on the plastic. You can buy light stands or mounting clips easily. Keep your frog toasty-warm!
