I mist at night test before I go to bed. But I have need misting just slightly in the mmorpg's before leaving Cus of the humidity issue. Not a lot though. 3 squirts usually. An ill look to see what meters they have. Cus I know the meter did get a bit damp but I mean it's a hydrometer... They're going to be in damp places. Dumb ppl making meters are dumb. Lol.
