Re: How does microwaved water effect plant growth?

I don't know of any reason why water boiled via a microwave or boiled on a
stovetop would have different effects on plant growth unless there is a major
difference in how and how long they are boiled. For example, if the water on the
stove was boiled much longer so that 90% of it boiled away versus the water in
the microwave being boiled briefly and in a covered container so no water boiled
away. In that example, the water boiled on the stove would have a concentration
of salts ten times that of the microwave-boiled water.

I'm assuming that in both case the water is cooled back to room temperature
before being applied to the plant. Did you find a major difference? It seems
like boiling water first before using it for plant irrigation would be a waste
of energy.

A more relevant project with plants and microwaves would be to determine if
microwaving seeds affects seed germination.
