Hydroponic turfgrass athletic field and landscape apparatus

A process for growing turfgrass using a hydroponic irrigation system, the process comprising the steps of:

• pumping out used water from a field module, through a solenoid valve, wherein the field module comprises a horizontal spring layer for absorbing vertical forces exerted by external loads and a steel grid layer positioned on top of the horizontal spring layer for holding a plurality of turf sods;
• storing the used water in a used water tank;
• disinfecting the used water received from the used water tank using ultra-violet (UV) rays;
• adjusting a pH level and electric conductivity level of the disinfected water, using a water quality management unit;
• conditioning temperature of the water received from the water quality management unit, using a geothermal unit;
• and
• pumping the conditioned water received from the geothermal unit into the field module through another solenoid valve.

A hydroponic field irrigation system for growing turfgrass, the hydroponic field irrigation system comprising:

• a field module for growing the turfgrass;
• a used water tank for receiving water from the field module;
• an ultra-violet (UV) unit for disinfecting the water received from the used water tank;
• a water quality management unit for adjusting a quality of the water received from the ultra-violet (UV) unit;
• a geothermal unit for conditioning a temperature of the water received from the water quality management unit;
• and\a plurality of solenoid valves for pumping water into and out of the field module,
• wherein the field module comprises:
• a horizontal spring layer for absorbing vertical forces exerted by external loads;
• a steel grid layer positioned on top of the horizontal spring layer for holding a plurality of turf sods;
• and
• a slidable sheet layer positioned below the horizontal spring layer for assisting the horizontal spring layer to move horizontally.
