I'm looking for the most cost effective to keep his cage temperatures up. http://www.youtube.com/watch?v=6Wyvj3sSNqI in the video it is said that that particular radiant heat panel wouldn't require a thermostat (buying a separate thermostat is an extra cost I cant afford with the extra 100 bucks for the radiant heat panel). I live in Florida (the temperature tends to be in the 70's-80's normally) but when we have the cold fronts come down the room temperature does get into the 60's. I'm planning for this drop in temperature since winter is just around the corner. If heating this plastic cage is too tedious I might go for this rack http://www.reptilebasics.com/iris-sw...y-or-back-heat with 4' flexwatt belly heat. Would the rack be better at keeping the ambiant tub temperature when it does get colder?
