A hydroponic farming system has seed germination, seedling growth, plant picking, cool storage/shipping and equipment cleaning areas arranged to follow the flow of the plant processing cycle. Plants are started from blocks of seed cubes arranged on wheeled trolley germination tables having tiered and sloped top surfaces across which water and nutrient solution are flowed from headers supplied successively by spaced overhead lines, to collection channels discharged to subsurface returns The cubes of sprouted seedlings are then separate and transferred to wheeled trolley growing tables, where nutrient from overhead lines is distributed from lateral weirs, through longitudinal inclined trays, and lateral footers to subsurface returns. The trays of the growing tables have central depressions and include covers with downwardly extending flanges to prevent spraying of the tray sides.
