Hello all! I can't seem to find exactly where we should measure humidity. I am building a enclosure for my ball python and will be using Arduino to get my measurements for humidity and temperature. I am making a bioactive terrarium and figured just because I can I will put thermostats on cold, middle, and hot side.
My question comes in here though, for humidity should I grab humidity in those three places (which I could) or should I do two (Hot, Cold), or would one in the middle 1" above the substrate be fine?
