Abstract: A method and system for use therein for providing O2 and H2 gases directly to the soil proximal to the roots of plants via electrolysis is described. The method employs at least one electrolyzer disposed adjacent to, or inline with, the irrigation waterline of the plant grow operation to facilitate the introduction of the gases to the soil. A power source is used to provide the electrolytic conversion, and gases remain in a micro-bubbled form to flow through the waterline more easily to the plants where they are needed the most. A venturi is used to channel the dissolved gases in the waterline from the electrolyzer in embodiments having an external HyGrO unit. The inline embodiment electrolyzes the water without need of a venturi to reintroduce the gases to the waterline.

Abstract: A dispenser selectively mixes one or more chemical fluids into a motive fluid such as water by using diverting motive fluid to one or more channels formed in an eductor body, at least one of the channels being an eductor. When the motive fluid passes through the eductor, a selected chemical fluid is eductively drawn into the venturi of the eductor, producing a mixed fluid having a desired total flow rate and dilution ratio. Additional dilution ratios, flow rates, and chemical fluids are selectable by diverting motive fluid to another channel or combinations of channels. Carry-over of chemical fluid between dispensing is avoided by diverting the motive fluid rather than by diverting the concentrated chemical fluid.

Abstract: The present invention reveals a method and apparatus for more efficiently injecting a primary fluid flow in a fluid ejector used to pump lower velocity fluid from a secondary source. In one embodiment, the primary fluid flow is a pulsed or unsteady fluid flow contained within an inner nozzle situated within a secondary flow field. This secondary fluid flow is bounded within the walls of an ejector or shroud. The secondary and primary fluid flows meet within the ejector shroud section wherein the secondary fluid flow is entrained by the primary fluid flow. The geometry of the ejector shroud section where the primary and secondary fluids mix is such as to allow the beginning of primary injector pulse to be synchronized with an acoustic wave moving upstream through the ejector initiated by the exiting of the previous pulse from the ejector shroud. The ejector's geometric properties are determined by the acoustic properties, frequency, duty cycle, and amplitude, of the pulsed primary fluid flow.

The outlet passageway is spaced a predetermined distance downstream of the venturi inlets to prevent substantial backflow of the first secondary fluid mixture into the second venturi passageway prior to mixing together of the two streams in the outlet passageway.
