A hydroponic electroculture system is disclosed for use in a hydroponic growing environment. In at least one embodiment, an at least one electroculture unit is positioned in fluid communication with the hydroponic growing environment and provides a conductive core comprising an absorbing layer sandwiched between a pair of opposing first and second conductive layers; each of the first and second conductive layers being in electrical communication with an at least one electrical wire. With the absorbing layer saturated with the fluid of the hydroponic growing environment, an electrical current is selectively delivered to each of the first and second conductive layers which, in turn, forms a reaction within the absorbing layer that causes an off-gassing of oxygen and hydrogen in the form of bubbles to be delivered, along with the electrical current in the fluid, to the roots of an at least one plant in the hydroponic growing environment.

The present invention provides a gas generator and comprises an electrolytic cell, a condensate filter device, and an atomizing device. The electrolytic cell is for electrolyzing electrolyzed water to generate a gas with hydrogen. The condensate filter device includes a gas pathway, a filter, and an isolated component. The isolated component is used for limiting the movement of the filter inside the gas pathway. The gas generated from the electrolytic cell is condensed and filtered through the filter for generating a filtered gas with hydrogen. The atomizing device is used for generating an atomizing gas to be mixed with the filtered gas to generate a healthy gas. The present invention uses the condensate filter device to filter out the electrolyte from the filtered gas with hydrogen to be mixed with the atomizing gas for generating the healthy gas.
