the same question pops up time and time and time again. the post normally reads as follows: i just got a new (insert brand here) vivarium and no matter what i do, no matter how much i mist, my dial gauge reads only 40% humidity, what am i doing wrong?"

answer, you are doing nothing wrong. but there are a few things you need to look at. first, is the screen top completely open? if it is, try covering it with a piece of glass, plexiglas, plastic wrap, damp towel. second, if you are using an analog hygrometer (the gauge that reads humidity), throw it in the trash and get one that is digital. the analog hygrometers are notorious for being inaccurate.

there could possibly be other reasons for low humidity readings. but these are the most common ones.

if anybody would like to add to this, please do so!!
