Whoa thats a great point.
I don't think there is anywhere else for water to enter the room. Row of closed windows and the rest is concrete. Above the ceiling is a deck with surface sealed with vinyl sheet. Everything is very dry. Room has some large closets with good doors and the air in the closets is bone dry. I guess suggests water isn't rising from the crawl space, maybe its outside air condensing on the floor?
The room's door faces the garage entry door and around this time of year the cars are always wet and stay wet. Could be the moisture is humid air from garage.
Could be I collect more water in the warmer spring because that is when the air is most humid outside.
Is tough to judge relative humidity between room and crawl space because there is such a temperature difference and that crawl space smells like concrete. Distorts my sensors.
I think I need data - going to borrow or rent a moisture meter.
