The application of electricity, magnetism, monochrome light, and sound can stimulate the growth of plants to a great extent. This little-known technology, called Electro-culture, can accelerate growth rates, increase yields, and improve crop quality. Electro-culture can protect plants from diseases, insects and frost. These methods also can reduce the requirements for fertilizer or pesticides. Farmers can grow bigger and better crops in less time, with less effort, and at a lower cost.
The several approaches to Electro-culture include: antennas, static electricity, direct and alternating current, magnetism, radio frequencies, monochrome and intermittent lighting, and sound. The energies are applied to the seeds, plants, soil or the water and nutrients. - Robert A. Nelson"

"Growing plants by tapping in to natural energies; such as the telluric currents of the Earth, solar radiation, heat/cold, and wind. Results in a large gain in crop yields, more hardy plants, etc."
ahh... it seems someone else wrote about it earlier: http://www.thunderbolts.info/tpod/2010/arch10/100630biology.htm
