I need scientific studies on communication between phsyically
separated plants. The studies will show electrical changes
in the bio-matter. Any help please.

I have found that the transmission medium for the plants and animals is not in the EMF spectrum. I dont know what to call the
spectrum the energy is apart of, "But" I do know that if you illicit a reaction from one bio unit and observe the electrical change of that bio unit, and the change in the 2nd bio unit, there should be
a significant difference from there resting baseline state.
I am also looking for cheap battery powered electronic equipment.
such as ( LCD oscilliscope, frequency generator ) or a schematic
to build said items. I have built an ELF antenna and it will
pick up from 0 - 150 hz.
I used my computer and a program that
accesses the sound input and displays the signal from electrodes "But" I also
pick up anything on the house lines as well... hair dryers ect.....
That is why I need to find or build the battery powered equipment. Remember the scientific studies as well.
Thank you.

Pop in to your local university library, and do a search in www.sciencedirect.com
