i see that you live in washington. unless you have a dehumidifier in the room your local humidity along with your 2-3 sprayings a day will be sufficient. to much humidity all the time will cause fungus and uri's.
I'm not really sure what it usually is here. We just moved to Spokane like five months ago. I lived on the west side for almost 20 years and it is noticeably dryer here. We visited the west side a few weeks ago and shortly after getting into Seattle we were sweating from the added humidity. Dory loved it on the west side. She was showing her relaxed and happy colors alot more when we were there.
