...for the survival of the flowers; the O3 was keeping the pathogens at bay that would normally be breaking things down.

I don't know what the concentration of the O3 was, just that it was high enough that you could leave the water (unopened) on the shelf damn near anywhere for a year, and it would still be good.

I agree that an experiment should be done to really determine the effectiveness, and I suspect that you're right, Rusty, that (if such effect can be proven) the most beneficial place for it would likely be in yer cloner.

I think I'm going to set up (next batch) a test where one cloner gets the O3'd water from my supermarket, and one just gets carbon-filtered tapwater. Hell, I might even try a control group that just gets tap water, a la Weez...
