Throw the tank out the window and get a generic Sterilite tub and drill some holes into it! It worked wonders for me! You can cover the mesh with a damp towel or plexiglass and that should boost it up a little bit. I know in the first month having my BP i fought the humidity in the tank and finally gave up and bought a tub though. Not as asthetically pleasing but it gets the job done and honestly my snake seems a lot more comfortable as well. Hope this helps!
