Abstract: There is provided, in a preferred embodiment, a hydroponic apparatus for growing plants within a confined space. Plants rooted in removable containers are placed within a receptacle that rotates on a vertical axis. During hydroponic fertilization a recirculating system delivers and transfers the nutrient solution to and from the receptacle. The plant container in the preferred embodiment allows for removal, replacement, and repositioning of plants within the receptacle. The preferred method increases the photosynthetic service area of the light source in a confined space by arranging a plurality of hydroponic apparatus beneath the light source. The combination of removable containers and rotating receptacles with a plural arrangement of apparatuses prevents algae growth, empowers the grower with plant manageability, and amplifies plant productivity.
