A multi-layered gravel hydroponic system comprising at least one trench dug into earth, a sheet of fibrous capillary material laid over the trench, sand that fills the trench, a layer of sedimentary-type pea gravel over the sand and capillary material, and a conduit extending into the sand trench to provide fresh water during watering cycles. When combined, the sand and fibrous capillary layers irrigate seeds and roots imbedded in the pea gravel, which provides the growing nutrients. Because the pea gravel is derived from organic material, its natural composition of various minerals provides a nutrient environment to sustain root growth. The resulting structure replaces the need for soil and fertilizers. By watering beneath the pea gravel, nutrients inherent in the pea gravel travel with the water to evenly feed roots throughout the growing region.
