An automated hydroponic growing and harvesting system for sprouts includes a continuous serpentine chain conveyor transporting suspended trays through a tray preparation zone where trays are cleaned, a seeding zone where a layer of seeds is deposited across each tray, a germination zone where environmental conditions and nutrients and water are provided for germination, a growing zone where lighting, nutrients and water are provided for growth, and a harvesting zone where sprouts are dumped from each tray.
