A hydroponic grow system for growing plants. The system includes a main reservoir, at least one plant reservoir that includes a spray head and a fill pump. The fill pump fills the at least one plant reservoir by pumping a water and nutrient mixture into the plant reservoirs through a spray head. A controller drains the water and nutrient mixture from the at least one plant reservoir and a control reservoir in a predetermined manner such that a siphon is created to provide a flow of the water and nutrient mixture to the at least one plant reservoir.
