For future reference, you should always set up and test (temps & humidity) the entire enclosure for a week BEFORE you put a snake in it...it takes time to make
sure it's correct & it's better not to stress a new snake while you're tinkering with things. If it's any consolation, this is a typical "new snake owner" mistake.
With a new snake trying to settle in, it's no time to find out your heat sources are inadequate, & finding or ordering additional things that need tested takes time.
