How critical is water type?

That's very interesting, thank you for the info.

A question I had about water that hit me the other day--I was told by the local supermarket florist that distilled water is good for flowers because it lacks the normal impurities that regular tap water does, but then I was wondering that since it has been distilled, doesn't that take some of the oxygen out of the water? and shouldn't plants have water that has more oxygen in it?
