Abstract

The subject invention is an electrostatic plant watering system for the delivery of water and nutrients to the roots of plants. The system provides water or another fluid from a fluid source or container using a pump. The pump provides a pressurized fluid at a constant flow rate through a nozzle at a low pressure, which sprays a fine mist of particles through a conductive metallic ring that is electrically charged by a voltage source. As the fluid particles pass through the center of the electrically charged ring, the particles themselves become charged, allowing them to attach to the roots of a target plant positioned at a selected distance away from the electrostatic plant watering system.
