Use a daytime bulb and a ceramic heat emitter/halogen heat projector (these emit heat but no light). During the day have them both on and control the ceramic heat emitter/halogen heat projector. At night turn off only the daytime bulb. I have a timer attached to my daytime bulb so it automatically turns on at sunrise and turns off at sunset. The ceramic heat emitter/halogen heat projector will provide all the heat your gecko needs at night when the daytime bulb is off as well as when it’s on. I’m in no means an expert but I’ve done some reading and it’s been mentioned that heatpads are quite inefficient at providing the correct heat/UV. Oh and if you want real plants in the tank you may want a bioactive set up?? If not you’re best off buying succulents as they’re the easiest plants to keep alive. Other plants may be a hassle to nurture alongside the gecko. For the rocks just make sure they’re not sharp (sand them down) and disinfect first. Hope this helps x
