A quick update on my experiment to see how feeding plants water boiled in a microwave oven affects their growth: after around three weeks, the microwave plants are doing just fine – as are the other two sets given non-microwaved water. Apologies for picture quality but hopefully it’s clear we have three sets of healthy sprouts here.
It may appear the microwave plants (komatsuna spinach mustard) are a little smaller than the others. However, the sets given straight filtered water (left) and filtered water boiled conventionally on a stove (right) have a fairly wide range of plant sizes, while the microwave ones are more uniform. On average, growth is about the same for all three pots.
At this stage, it appears that feeding plants filtered water boiled in a microwave oven (and then cooled to room temperature) has no affect on growth. If you are wondering why I am testing this, please read part 1 of the experiment. You will find more details on the original claim that microwaving water damages its structure and causes the formation of dangerous radiolytic compounds – something that would affect any food cooked in a microwave oven.
