Study Hints Ambient Radio Waves May Affect Plant Growth

dwguenther writes "A Lyons (Colorado) area woman with no academic pedigree has published a scientific paper in the International Journal of Forestry Research about the adverse effects of radio waves on aspen seedlings. Katie Haggerty, who lives north of Steamboat Mountain, found in a preliminary experiment done near her house that aspens shielded from electromagnetic radiation were healthier than those that were not. 'I found that the shielded seedlings produced more growth, longer shoots, bigger leaves, and more total leaf area. The shielded group produced 60 percent more leaf area and 74 percent more shoot length than a mock-shielded group,' she said." This was not a definitive study, as its author readily admits — it's hard to see how a double-blind study could even be designed in this area — but it was refereed.

Double blind study

it's hard to see how a double-blind study could even be designed in this area

In the medical field, it means that both the patient and the doctor evaluating the symptoms don't know who received a placebo.

For this experiment - setup two antennae in front of some seedlings, have a different dude turn one of them on. The person measuring the seedling growth doesn't know which were exposed to radio waves. That's all you need to make sure the study doesn't have some bias in it.

The study surely needs to be blind from the researchers point of view, this sort of this is just begging for confirmation bias.

When it's a medical study, it's accounting for a patient's bias.
Scientists can have bias as well, this is why researchers use the double blind method to eliminate their personal bias from the results.

Personally, I think the shielding worked more as a cozy for the plant and gave it a more stable immediate environment upon which to grow. Perhaps even the faraday cage was diminishing the light around the geraniums, so they spent more energy growing their leaves bigger to compensate. Given my personal bias, I wouldn't of published yet since I know there couldn't be a correlation. There are any number of reasons why a bias of opinion might be involved and there is any number of reasons why plants in a cage could grow better than plants not. I doubt she had the soil, in which the roots were, wrapped with a faraday cage either.

Re:No double-blind?

Yeah, that's pretty much what she did. Wasn't double blind, but she used real Faraday cages and placebo cages in fiberglass, along with another non-caged control. Should be easy enough to replicate, only with uninformed interns watering the plants.

"fscking amateurs. foil absorbs light and causes hotspots on your "pepper" plants."

LOL. I have *NO* problems with any of my foil-lined boxes. ANY improperly-done reflective job will create a hot spot, INCLUDING MYLAR, which is the stuff we use for an EMERGENCY BLANKET.

"Of course if you weren't really growing peppers but something like medical marijuana then you'd want to know that experimentation shows that grow is no better under targeted spectrum LED than it is under select HID lighting. In fact, it takes just as many watts of LED to get the same effect so you don't save electricity there."

Dead wrong, sir. I am a licensed medical patient, as well as a breeder for the Dutch (I preserve landrace genetics found in the wild across the globe,) AND I do indoor NFT hydroponics sheds across the globe which are illuminated by LED, and your statement is factually incorrect. From wheat, to tomatoes, to medical cannabis, I've regularly achieved higher yield per kilowatt-hour with LED versus HID. Also, with LED, the resulting product is more potent, as there is no green or yellow light, which plays an inhibitory and regulatory role in most non-marine flora.

In fact, I replaced 832w of *VERY SELECT* HPS and T5HO lighting with 350w of my specially-designed LED lighting and get the same results.

I know why LED panels fail to yield. That research went into my own panels. Also, most panel manufacturers use the CHEAP 1w diodes. Those bottom-bin pieces of garbage aren't worth the sapphire substrate they're laid upon. That's also incidentally why the garbage LED panels are so cheap.
