Wow you come on here to ask question, people tell you the answers from YEARS of experience. (some people have 20+ years keeping snakes) And you are telling the BP.net community that we are wrong.
All that is being offered is help whether you like what we have to say or not it's the proper not "proper" way to house your snake.
Just to cover the basics:
Your cage is too big
You don't need a screen hood, a plexiglass sheet cut to size would work
You don't need a heat lamp
Your feeding needs to be every 7 days and a smaller meal
4 UTH can be fixed by insulating the sides of the tank (3 sides need to be covered anyway)
And that is just a few things..........
