Question on buying a "hood" for my BP's terrarium.(Advice please)

[MitsuMike]

This sort of confrontational attitude isn't really helpful.

And to touch on the specific comments you made...

Your cage is too big
-- Not necessarily...some balls do just fine in larger enclosures and if that is what they prefer and they don't mind putting in the extra work it takes to maintain it, then there's nothing wrong with it.

You don't need a screen hood, a plexiglass sheet cut to size would work
-- There must be some sort of air exchange going on. A solid plexiglass top would be unhealthy, at best.

You don't need a heat lamp
-- You don't know that. If the home is kept cool, a heat lamp may be an essential supplement to keep the overall ambient temps up enough.

Your feeding needs to be every 7 days and a smaller meal
-- Smaller than what? It already seems like they may be feeding a little smaller than optimal...but since we can't actually see the snake or the prey item, we really can't judge that at all. All we can go on is the little bit of description they've offered.

4 UTH can be fixed by insulating the sides of the tank (3 sides need to be covered anyway)
-- This is actually a pretty novel idea. Never thought of it or seen it suggested before this. A person would need two different thermostats to make a set-up like this work...one for the heater UNDER the tank to create a warm basking spot...and a second for the three heaters on the sides to maintain a steady ambient temp. Not 100% sure if this would work in a really cool room, but it might be worth trying.

Agreed, I was a bit harsh. But it was quite rude of someone to ask for help and then deny it but that is neither here nor there. The OP is here to learn so let me elaborate on the following that JLC got confused on.

As far as the plexiglass top instead of the screen it will work just fine. All that needs to be done is a few holes drilled in the lid like people do for the tubs and you get airflow and humidity.

Food wise, the prey being offered was a large rat. Most people feed mediums at max to their adult females. Large rats might be the width or the proper size but can get the BP fat and thus leading to an unhealthly life.

As far as keeping ambient temps up do the following along with the plexiglass lid:
You can go the UTH on the side walls route if this doesn't work first
Buy cork board and cut to fit the 3 sides of the tank and tape them on. This should help keep the glass from dissipating the heat from the tank out into the external environment. If this doesn't work invest in some flexwatt which is cheap and wrap the 3 sides of the tank in it (1 strip running along all sides). Then place the cork board on top of that. Set thermostat to the ambient temp needed and the flexwatt should heat the tank likewise.
