I'm curious as well, especially when considering humidity. Here in Colorado we've had two summers of historically high humidity. Last year humidity rolled in, the prairie greened, and then later the rains came. This year, the prairie has been green all summer thanks to rain and humidity. We've never had humidity like this so I never realized how important humidity was for plant growth. I had always given rain more weight than it deserved.
