Actually they are right. See it grabs onto whatever water it can. When you fire the newly saturatedwick its still grabbing some water from the air. When you blow on it more is coming in contact with it so it makes more vapor same as when you inhale. If something is hygroscopic then that's just how it works
Yeah but 64 ounces of it? How much water does it grab? If you vape one milliliter how much does 1 milliliter absorb? Assume a 1 to 1... that would 1,800 and some change milliliters to vape.
All one needs is their daily intake of water.. which includes fruits and vegetables.. If you more active, then of course more water.
