That's superb set of instructions! My heartfelt thanks for you dear CraigD.
But, I have a lingering doubt! I wonder if the expermenter in the linked article implied that the water was boiled in a microwave oven every day, before it was used for watering (after cooling ofcourse) or whether microwaved water was stored for the period of the experiment (as is suggested in your procedure).
I would therefore suggest that experimenters should try both approaches.
