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.
You're totally right on the KIS thing, Rusty, but if I may offer a personal experience of a few years ago?

Me and the now-Wife were living in Calgary a few years ago, and still in our 'honeymoon phase', and so I was buying her cut flowers on a regular basis. Roses would usually last about four to five days in the vase in the kitchen.

One day either the wife or I was being impatient with my brita filter, and so they got watered with some heavily ozonated distilled water that we kept on hand for emergency purposes (the ozone gave it a hell of a shelf-life).

We found that roses would last three weeks, sometimes more, if they were watered with this stuph, instead of R/O, normal distilled, tap, brita, etc., and with no scummy stuph around the base of the vase. The roses seemed to flourish with the water, as well.

I wish I could find someone who was doing that out here, but I've used the distilled/mildly-ozonated and springwater/mildly-ozonated from my local grocery store, with no ill effects.

I think what happens is that the O3 breaks quickly down into O2 and O1, with the O2 being great for roots, and the O1 deadly to pathogens. I hadn't thought about it killing off the beneficials, tho. That could pose a problem...

I am only an egg.
