I used the Natural Action Water on my wheat grass . When I purchased the Natural Action Water DE Portable I told myself that I would have to see or experience clear and concrete benefits, so I did a test and used regular tap for one tray and Natural Action Water for the other . Right from the beginning there was a marked difference, and it’s very clear in the finished trays. My 2 grown sons were entirely doubtful. But when they saw the wheat grass trays they wanted to use it at every opportunity! One glance at the trays tells the difference, you do not have to hem and haw and try to figure it out etc. Very amazing!
