WiFi Kills House Plants

Dead plant in potsIf WiFi can kill your plants, what is it doing to you? The Daily Dot has the story:

Are you slowly killing your houseplants? Probably! But there might be a reason (other than neglect) why they’re all yellow and wilty: your Wi-Fi router.

An experiment by a handful of high school students in Denmark has sparked some serious international interest in the scientific community.

Five ninth-grade girls at Hjallerup School in North Jutland, Denmark, noticed they had trouble concentrating after sleeping with their mobile phones at their bedsides. They tried to figure out why. The school obviously doesn’t have the equipment to test human brain waves, so the girls decided to do a more rudimentary experiment.

They placed six trays of garden cress seeds next to Wi-Fi routers that emitted roughly the same microwave radiation as a mobile phone. Then they placed six more trays of seeds in a separate room without routers. The girls controlled both environments for room temperature, sunlight and water.

After 12 days, they found the garden cress seeds in the routerless room had exploded into bushy greenery, while the seeds next to the Wi-Fi routers were brown, shriveled, and even mutated. See for yourself:

Teacher Kim Horsevad told the Daily Dot that her students did the test twice with the same results. She was quick to point out that while the students did the experiment to test only one variable to the best of their ability, it is a high school experiment and this isn’t a professional study…

    Break out your tin foil hats people!

    Even the most casual knowledge of radio waves has made me cautious. Its a radio transmitter emitting radio waves, which can be harmful….DUH?! The ignorant mass consumers will suffer as always.

      Oh please, you can’t separate yourself from “ignorant mass consumers” with a “casual knowledge of radio waves”

  • Kenneth Pastore

    Like the popular story about plants near microwaves this is a high school project. While I don’t argue the idea that cellular development is affected by radiation (anything that enters a system changes the system) this experiment would have to be performed in a lead box with no other waves but the WiFi signal.

      If anyone has the time & inclination…
      I believe a better study would contain 3 groups, 2 experimental and one control. Group E1 would be put into a faraday cage with a WiFi Router, E2 would be kept in a faraday cage w/o WiFi, and Control would not be in a faraday cage.

    5 ninth grade girls did the study. Maybe they should be in contact with Al Gore.

      Yeah! and everyone knows that Global Climate Change is hooyey!

        lol at “climate change”. You mean “weather”

  • Dmonix

    This is bullshit, My family, my two Brother’s have a house full of “house’ plants and NONE of them are dying anymore than they were dying without “Wifi”… fear mongering crap…

    • Zachary Reed

      Same here, My philodendrons are not affected by my wifi in any way.

      Just like radiation exposure in the womb, which can cause massive birth defects from tiny DNA damage during rapid cell division, a sensitivity in developing organisms to WiFi may be enough to make consumers (esp. those with progeny) afraid and/or outraged.

      And my 3 best friends have been smoking cigs for over 50 years while I made it to 44 years and was nailed by Laryngeal cancer..( which is caused primarily by smoking cigs) go figure..at least some youngsters are conducting worthwhile experiments!

    I love the simple logic, repeat the experiment a few times and see the results. I suspect these kids discovered something important for our future health and safety.

    Sounds like this hit too close to home for some “awake” disinfonauts.

  • LOLarry

    This was first reported in May, and has been widely dismissed. There are multiple wifi signals on my street, and exponentially more healthy plants.

  • kowalityjesus

    ANY level of information is better than none, which coincidentally happens to be the median…

  • Mr Grim

    It’s funny how so many posters on here are happy to leap onto the slightest evidence of “the man” in all his guises trying to harm them in various subtle or not so subtle ways… unless it’s somehow connected with their own precious tech, in which case it’s a case of “Set defensiveness and denial to maximum power!”

    I’m not saying that it isn’t a valid response, cos at the end of the day what would I know, I’m no expert. But it’s an interesting response pattern.
