a google search of this topic brings up a wealth of concerns and information for either side- so who knows. I own a microwave but rarely use it. They give me the creeps a little and besides the food tastes yucky. The fact that you are asking the question (about the seeds) is enough concern to yourself that you should just move your plant to another location and then you won't have to worry about it. Or am I understanding that you are wanting to see on purpose if they are altered as a sort of experiment? You could raise a plant on the microwave and then one in another room and then plant the seeds and go from there with the results, but again there are lots of variable factors that would make your outcome maybe not entirely sure. And it could take months (or longer) to see results. It sounds interesting though. I would love to read later, how your experiment turns out.
