Earth and Grow, shocking your plants?

So in a recent issue of HT I read about this product that was recently developed by some college kids that you stick a electric probe in your soil and it gives it a minor charge in the soil (idk if you can use with hydro since my mommy always taught me electricity and water don't mix, but would be interesting). They claim in their tests they have done that CBD and THC was increases using this. I understand the concept that the earth is a giant magnet and magnetic fields give off some electricity so to some extent all the soil has a very low charge to it but does this really make the difference from indoor to outdoor? In many cases I hear of indoor being better than outdoor when grown under proper conditions. There deluxe package (probably the one I would go with) is $200 so its a little bit of a thinker but since I can't seem to find any threads on here with results I found myself wondering if I have to be a pioneer with this technology and document it for others. Let me know your thoughts on this product please, I want it but would like to see some results first. Happy Burnin

Before I spent anything I would want to know the exact science behind it. Not the applying of juice but why the application of juice increases either. In other words, just why does this work? $200 for a low voltage DC device seems a bit much at first glance.

Magnetic fields can only induce an electric field if they are dynamic. Maxwell's Equations describe how an electric field will be created with a changing magnetic field: dell cross E = - dB/dt . I'm not sure what you're talking about, but it has nothing to do with the earth's magnetic field.

Thats what I'm wondering.... I get the science, it makes sense when you think about the fact that the earth is a giant magnet (otherwise compasses wouldn't work) and when you have a magnetic field there is a electricity created, so there is some of amount of current going through the soil but I feel like this would have been thought of long ago since it is not new to know that there are magnetic poles otherwise it can not possibly be significant that we wouldn't have noticed the difference from outdoors to indoors other than the fact that we still can not perfectly mimic the sun... As I stated I'm not a skeptic of the science, I am a skeptic of the results though....
Edit: My bad forgot that part of class (smoked in hs too) could have swore ANY magnetic field made a current but I stand corrected. What I get for quoting things I have little understanding of but this is why I started the thread in the first place because if you are correct mc which i don't doubt, then it begs the question of why shock your babies then?

i hate bumping threads but still can not find actual eveidence of these claims

My best guess is that whatever you're referring to is some sort of applied voltage to the soil. This might affect the pH of the soil, but that is pure speculation on my part. They might be trying to utilize findings of this paper: http://www.plosone.org/article/info:doi/10.1371/journal.pone.0002963

Here is the abstract:

It has long been known that there is a sustained electrical potential (voltage) difference between the xylem of many plants and their surrounding soil, but the mechanism behind this voltage has remained controversial. After eliminating any extraneous capacitive or inductive couplings and ground-mediated electric current flows, we have measured sustained differences of 50–200 mV between the xylem region of a Faraday-caged, intact, potted Ficus benjamina tree and its soil, as well as between its cut branches and soils and ionic solutions standardized to various pH values. Using identical platinum electrodes, no correlation between the voltage and time of day, illumination, sap flow, electrode elevation, or ionic composition of soil was found, suggesting no direct connection to simple dissimilar-metal redox reactions or transpirational activity. Instead, a clear relationship between the voltage polarity and magnitude and the pH difference between xylem and soil was observed. We attribute these sustained voltages to a biological concentration cell likely set up by the homeostatic mechanisms of the tree. Potential applications of this finding are briefly explored.

I don't know if what I was trying to get at before was very clear, but I was trying to show you that the earth's magnetic field is very weak, and relatively stable(we can use a compass for navigation). Therefore, with little change in a magnetic field, there will be little electric field generated. As I said before, the earth's magnetic field is not a player.. the same can be said for any other magnetic field induced by currents in your wires and the electric fields generated by their fluctuations will be very weak (unless you're running some sort of superconductor, then you're going to want to account for this when you shut it down...)

Without a time-dependent magnetic field, there will be no electric field generated. The magnetic field must change its strength with time in order to generate an electric field. That is what the one of Maxwell's equations above says.

Well my theory of how these are replicating what I thought the earth was doing is out... So why shock them then? Anyone done a run with them yet? If you do a organic grow or subcool's super organic soil do you think this would be harmful or beneficial to the beneficial bacteria and myco?
I like what that link was getting at but was a little beyond me since I have been dabbing a lil bit lol, if I understood right, the ph of the soil makes the plant and soil kind of complete a circuit and has a small charge? Please correct my thinking, not an easy theory for me to wrap my head around...
Re-re edit: read your summary again and think its something else you meant entirely, the plants basically react to the minor charge (mV being micro volts right?) put into the soil and this can help with up take of nutes it seems then since it affects the root zone?
