System and method for manipulating an electrical potential of plants and alternatively for manipulating an electrical charge of dispersed particles that interact with the plants

A method for manipulating an electrical potential of a plurality of plants, comprising:

• electrically and mechanically connecting at least a first plant electrode to a first plant of a plurality of plants;
• electrically and mechanically connecting at least a second plant electrode to a second plant of the plurality of plants;
• connecting the first plant electrode to the second plant electrode;
• connecting the first plant electrode to a DC power source;
• connecting the DC power source to a growth medium via a grounding electrode;
• and
• continuously providing DC power to the plurality of plants,
• wherein electrically and mechanically connecting the first and second plant electrode to the first and second plants comprises inserting at least a portion of each plant electrode into inner layers of the plant, in proximity to a lowest branching point of each plant.
