It is not a stupid move, just an inexperienced move. It is very difficult to keep the heat and humidity in the proper range in such a large enclosure. Also a lot of ball pythons go off feed in such a large enclosure, because they do not feel secure. You can alter the enclosure to try to fix these issues. If they do not work, then I suggest going with a smaller one; such as, a 20 gallon long.
Hope this helps.
