Biowave Harmonic Subsonic plant growth enhancer

Just got the latest edition of the Maximum Yield magazine (hydroponics industry magazine, kinda like the free music press of the hydroponics world) and noticed a particularly woo item as a new product, called the "Biowave".

Here's the blurb from the product review/advertisement on the site.

Quote:
The Green Revolution

The latest green technology in the indoor gardening industry is the Biowave. The Biowave is a machine that emits harmonic subsonic waves that enhance plant growth. Two models are available. The model designed for farms covers 10 acres and is solar assisted. The other model is for greenhouses and hydroponics. All you have to do is plug it in. With the Biowave you get more flowers, bigger yields and fewer insects. The Biowave comes with a three year warranty. Patent Pending in 160 countries. Ask for the Biowave at your local indoor gardening shop.
You can find a picture here at the site, just scroll down the page about 5 items in and you'll see a monstrous looking metal contraption.

So, whilst all my woo detectors are going off the scale, anyone want to take a stab at what this thing may be or how it might work? I love the "patent pending in 160 countries" statement, particularly considering there is a patent for a cat entertainment device. (laser pointer)

Hard to get any more information so far from ze interwebz, so if you come across any further info please post it here and hopefully we can rip this rubbish a new one. *sigh* Why did I have to be a skeptic in the world of plant growing?

Looks like woo to me.

There is very little info about this contraption, even on BioWave Industries websites (they have 3, and they still manage to say absolutely nothing), but I found one piece of absolute b.s. on their Facebook page:

Quote:
Utilizing sub-sonic harmonic waves, BioWave machines dilate stomata, which allows for greater nutrient intake = greater yield.
http://www.facebook.com/pages/BioWav...1394181?v=info
Uh, no. Just no. Stomata are what the plant uses to breathe. Nutrients are collected by the roots. http://en.wikipedia.org/wiki/Stomata

I wouldn't buy anything for plants from these people since they don't even know how plants work.

Well increased transpiration by forcing open the stomata would force the plant to take up more water, and the nutrients associated, so that's a possibility...

Still woo though. How on earth does "harmonic subsonics" open the stomata in direct opposition to the plants own regulatory mechanisms? And if you did that, you'd likely cause the plant more harm than good if they're "forced" open.

When I tried Googling this, I only found one article about ultrasonics (none on subsonics) enhancing plant growth -- from Mother Earth News 1984:

Quote:
ULTRASONIC PLANT STIMULATION
<snip>
It soon became apparent, though, that the seedlings receiving ultrasound treatment were growing much more rapidly than their control counterparts. In fact, by the fourteenth day the experimental plants were half again as tall as the ones in the "quiet" chamber.

The experiment continued for 28 days, the same period of time used in the photovoltaic root stimulation tests. By the end of the test, the plants treated with ultrasonic vibrations had grown an average of 87% taller than their control cousins. (The actual growth rates are shown in graphic form in Fig. 2.) Repetitions of the experiment were run to confirm the initial results, and some of the later tests showed growth rate increases of as much as 150%!
Unfortunately, this is just telling about a report that isn't cited.

This site has several articles (including the one from Mother Earth News) on How do plants respond to music, sound frequencies or harmonic sound waves.

I'm waiting for them to add "Quantum" to the name.

Dilating stomata is even a very bad idea, they are generally closed for a reason

But didn't Mythbusters prove that plants grow best on Death Metal?

I guess I could see how vibrations could help a plant pump sap around. Same way as exercise helps leg veins pump blood. And perhaps a certain freq will aid certain plants, freq to vary with species? And there seems to be some studies that show music is a plus for plants. And one good thing about sub-sonics, the noise won't bother anybody but the worms.

But hmmm, if all this is true, wouldn't there be some subjective evidence? Better crops along rail road tracks and highways? Trees that grow taller down town? Audiophile's house plants grow faster?

I guess I think there is just enough science to back up the product to make the field ripe for scams. I wish I had thought of it.
