The room with my miners currently has a humidity level of %12. The air is very dry, I am not sure at what point it will become a problem....or what I could do about it? I suspect a humidifier wont accomplish much as the hot air is being exhausted outside, so any humidifying I do will just be exhausted out as well I think.
don't mess with it, 12% is low but better than 70%+
in fact ideal range is between 30-60.
Just exhaust the hot air out and pull in outside air with filters, that should balance the humidity
