Hey Everybody

I'm interested in getting a ball python in the near future and I have a few questions. First off I'm probably going to be using some sort of tub. I hear glass enclosures are hard to keep humidity and heat. So I was watching this video on youtube and I'm wondering if this is ok to follow by:

And also I'm going to be using a heat pad and I'm wondering should I stick it directly on the bottom of the bin or will this burn the bin? And should there be space below the bin to let some heat out or no? The heat pad will be attached to a reostat or thermostat so it won't be overheating. And I've heard the basking temps should be around 88F-92F and an ambient temp of around 80F-85F is it alright to keep these temps 24/7? Or should the temps drop at night and if so how would I do this? And with the heatpad how much of the bottom of the bin should it cover? And I'm interested in buying these products for heating the tub,has anyone else used these and how are they?
