Note: This is far from conclusive, nor is it an original idea. Wish I had the time and space to do a real controlled experiment, but my hope is that is where the community comes in.

I grew four seedlings (two different strains - one indica; one sativa) under identical conditions except for the addition of electricity.

One plant used a solar panel putting out about 3.5 volts and one used a 9v battery. The electrodes were placed several inches deep about 1.5" away from the stalk.

Attached are the results after several weeks.

For those wanting to try this, I strongly suggest the use of gold plated electrodes as both of my copper electrodes quickly eroded. Also my solar panel was using my grow light as a source and was quickly shadowed by the leaves. My battery slowly drained.

For these reasons, I did not continue past a few weeks. If I were to do it again, I would use some sort of variable power supply to control both current and voltage and to be able to increase the stimulation as the plant grows. My electrodes were needle shaped, so the dispersion of electricity was very narrow. I think a gold plated screen would give a much larger surface area and would have even greater effect on the roots.

And, of course, more control plants are necessary to rule out normal variation in growth.

How does this work? Not sure, but something to do with accelerating ion exchange in breaking down minerals to make them more accessable to the plant.
