Experiment on the effects of microwave ovens using two similar plants:

Updated: Mar 14, 2023

About a year ago Brett and I listened to an interview segment on the dangers of microwaves where the interviewed, a medical doctor, mentioned that microwaves also killed the nutrients in foods and said that if one watered a plant with microwaved water the plant would die.

Later on, I stumbled upon an article by a school teacher who tried that experiment in a classroom showing images of two similar plants, one watered with tap water and the other with microwaved water. On the 3rd week, and after the plants went through some stress, the plant watered with microwaved water died. The teacher said that her family members stopped using microwave ovens. The article showed the shocking before and after images. I became even more curious and wanted to see with my own eyes what could happen.

Brett and I went to a nearby Pike nursery and purchased 2 nearly identical plants, 2 holding trays and 2 glass jars (to take plastics out of the question).

I then poured the same amount of tap water in the 2 jars, put one jar in the microwave and brought the water to a boil, then let it sit in the microwave (to avoid the water exploding on my face, which happens often when one heats plain water in a microwave oven.) and pour the water in the other jar in a pot and brought it to a boil on the stovetop.

I let both waters cool down overnight and started watering the plants with the same amounts of water the next day.

About 2 weeks later I noticed that the plant watered with microwaved water started losing leaves and was looking sad, and that it was absorbing a lot less water than the other plant, leaving a larger pool of water on the tray below.

My son Emilio suggested that perhaps the reason why the water would stay on the tray could be that the soil was compacted so that there was no soil at the bottom of the pot to absorb the water, so I checked it out, but the existing starting soil was still very loose on both plants and was compacted evenly.

I also noticed a brown dirt/water ring mark on the bottom of the pot of the plant watered with microwaved water, and also that the tray below had turned brownish as well. The pot of the other plant presented no stains.

Sometime around the 3rd week I noticed that the plant watered with stovetop water was getting low on soil, so I fed both plants with about the same amount of fresh organic potting soil thinking that it would give a boost of nutrients to both plants.

The fresh potting soil didn’t help the plant watered with microwaved water.

At this point it seemed to me that the water heated in the microwave might had lost its nutrients and also would not dissolve the nutrients in the soil. As a result the plant given the microwaved water kept loosing leaves and wasn’t growing new ones. I took a picture showing the tiny leaves on the top totally dried…

Two months since we started this experiment. The plant watered with microwaved water hadn’t grown new leaves and the existing ones were fading.

I decided to stop the experiment because the difference between the two plants were even more obvious.

January 29th 2023-

I started watering both plants with tap water with the intent to reverse the outcome of the plant watered with microwaved water.

February 28th 2023-

The plant that was fed water previously boiled in the microwave oven did not improve after a month of being fed with regular tap water, more organic potting soil and plant fertilizer.
