Welcome !!
As mentioned by a few already .. Thermostat essential ( maybe find a used one online ?) .. I swear by orchid bark / reptibark as it looks great and also natural plus it helps to keep the humidity up .
Here's a temp gun if you're wondering what they are ...mine cost ten dollars off eBay ( both items shown below can switch between C and F .
I also get these cheap thermometers ( with probes ) for about 3 dollars each and they're perfectly fine ( the only one that stopped working was a £20 from ExoTerra !)
