Ozone kills the beneficial biologicals in the soil, (not good) and will likely interract with other chemicals and chemical compounds in your nutrients and soil. Usually this is a bad thing. Spraying it on the plants might just kill the plants.
Ozone

Ambient air contains gasses that the roots need to properly develop and function. The root zone needs those gasses to be regularly replaced, and they get this via watering. When you water, suction draws-down the air into the soil. But if you oversaturate the soil, you force-out the air with moisture. (starving the roots of those necessary gasses)

Oxygenating additives are unnecessary crap, and potentially harmful to the plant and soil if used improperly.

Keep it simple.
Rusty Trichome Reviewed by Rusty Trichome on . oxygenated water in potted plants. The Mrs. tells me that she heard at her garden club that plants really like oxygenated water. She thought that I should try it. I know this is addressed in the hydroponics portion of this message board, but I am growing in soil and pots. And I had a tuff time making heads or tails out of the discussions. Oxygenated water is great for drinking. Also for cleaning the vegetables picked from the garden or purchased at the store. These are facts. Cause it kills a lot of stuff, hopefully only Rating: 5
