Look, don't overthink things. You need the following:
-ceramic heater or infrared - heat source- both ok to use at night too
- controller- of course on a proper settings to control the above mentioned heat source. Hydrotherm I mentioned earlier controls temp including night temp drop automatically.
- some sort of light for day/night cycle. Nothing special needed if frog is supplemented properly. You can get exoterra natural light - love that one or carry on with the one you have.
- spray bottle or fogger and whatever you put on top to maintain humidity is ok. A bit creativity usually needed and proper humidity/temp gauges.
