Congrats and welcome to the wonderful world of BP's...careful they are totally addictive. Tanks are pretty difficult to control heat at times and humidity. For the humidity you can use foil on the screen part to help hold in the humidity. Make sure your substrate is NOT wet or damp constantly though. When they go in shed an easy thing to do is take a wet wash cloth and cover the hot hide...this works really well to boost the humidity during the shedding process.

As far as the heating....you can do the lights but you will find that you are constantly having to check it. Also to be honest BP's do better with belly heat as they use that to digest. Now it doesn't mean you cannot use lights for the time being. When I was new I used them quite a bit at first. Now..I highly recommend eventually getting an under the tank heater. With those you will HAVE to use Thermostat to control it. Some stores will tell you that you don't need it. DO NOT LISTEN!! Those mats or heat tape can spike terribly. You can look for thermostats in places online like reptilebasics.com or spyder robotics. They are a little pricey....but well worth it in the long run. Hope that helps a little!!
