A hydroponic system may include a fluid reservoir configured to carry a nutrient solution. The hydroponic system may also include a fluid pump coupled to the fluid reservoir for pumping the nutrient solution and a Venturi aerator coupled to the fluid pump for generating air bubbles within the nutrient solution. A vortex generator may be coupled to the Venturi aerator and provide rotation to the air bubbles. The vortex generator may include a rounded chamber body having a sidewall and opposing first and second flat ends coupled to the sidewall, the first end being closed and the second end having an outlet passageway therethrough, and the sidewall having an enlarged diameter medial portion and reduced diameter end portions adjacent the first and second ends, respectively. The vortex generator may also include an inlet conduit extending through the sidewall.
