I bought an exo-terra large/wide terrarium, and I was hoping to get some advice on heating. The tank's measurements are 36"x18"x18", and I'm planing to get a UTH pad for the primary heat and a lamp for a basking/hot spot, but I'm not sure what size/watt I'll need? I'm also concerned that this might not be adequate, because the tank is so big and my ambient room temperature is pretty low. I'll be getting a thermostat and thermometers, of course, but I don't want to buy a lamp and mat only to find out that the ones I chose aren't going to work for me. This is my first reptile tank, so I just want to make sure I get all the equipment matched up right for my future snake baby.
Thoughts?
