Then you're all set, I too live in sunny and HOT south Florida and here's what's been working for me for over 20 years. block off the AC in the reptile room and open the windows! this will work about 8 months of the year. you're going to get heat build up if the windows are closed. in the winter close the windows and put an oil filled heater on a proportional tstat. No heat tape, UTH, RHP or lamps required. I guess the one catch might be that your keeping desert species and the humidity might be inappropriate.
That is my only true setback. But they're loving the heat too, trust me. When I was crashing with my friend, he kept his house a MAX 72° at all times and they were all so chilly. I'm so glad to have my own place, now
