I've got a exo-terra themo/hygrometer in my viv for three or four days now. At first the temp was round76-78 and humidity round 70%. Then two days ago yesterday I noticed the humidity had gone to 90 so I haven't misted but changed the water still. When I was feeding and cleaning today I noticed my substrate was nearly dry. So I've come to a conclusion that my new hygrometer is broke!? Is there a way I can check it or set (cant think of the word) it?
