i have a 5 tub rack. And well the temps and humidity are where they are supposed to be, but... how do all of you with racks keep track of your humidity. What I am trying to say is, how do i record the humidity in all the different tubs without having to buy 5 different hydrometers. I would only use one but I don't want to share hydrometers with the other snakes for obvious reasons. So how do all of you with racks do it? Please help!!
Thank you
