A method and system for use therein for providing O.sub.2 and H.sub.2 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.
