One week later - March 22, 2009

For the past week these two glasses have sat side-by-side on my bookshelf, they have been watered at the same times, and as you can see roots have started to extend downwards from the seeds. I have been careful to alternate their position relative to each other, to ensure the seeds don't benefit from an unnoticed advantage of the light. At this point, even with a magnifying glass, I can see nothing to suggest that the seeds on the left have been affected by being fed exclusively water that has been boiled in a microwave oven - in fact, on close inspection one sees that the roots on the left are a little longer.
