Well, doing a bit more research, I finally found some potentially important and inspiring information about applying free/alternative (electric) energy techniques to crops for more yield and other benefits.
I'll list a few important links for reading.
Here is a forum link full of great research/PDF links of academic papers. The main ones here deal with "Improvement of Mushroom Yield By Electric Stimulation." https://mycotopia.net/forums/fungi-magic-mushrooms/65286-improvement-mushroom-yield-electric-stimulations.html
Here is a link to Hemp Husbandry via electric stimulation in ElectroCulture: http://www.rexresearch.com/hhusb/hh5elc.htm
Here is an article about how Lightning (natural electric plasma phenomena) stimulates mushroom growth, and then how the Japanese scientists utilized this by producing "lightning devices" to simulate the effect on wood surfaces. http://news.nationalgeographic.com/news/2010/04/100409-lightning-mushrooms-japan-harvest/
Here is another article verifying this phenomena and then being applied to other various crops: http://www.pyroenergen.com/articles10/lightning-mushrooms.htm
Here is Paul Stamets, a renowned mycologist explaining in a lecture how mushrooms are the ultimate conductors of the plant world; they are the ultimate guides for the growth and stimulation of the other plant species. Wherever we have many mushrooms, we naturally have rich vegetation, from the cover crop to the tallest of trees. This covers the psychedelic mushrooms, for the benefit of humanity as well. http://www.youtube.com/watch?v=Wr35ynTvkPg
Here is a treasure trove of "free energy" devices developed over the years by a number of people. You can also find US government patents on some of them. http://www.rexresearch.com/index.htm
