An apparatus and method for growing plants with controlled rates of nutrient and water input. The apparatus and method include the use of a reservoir container and means to contain a growing medium. The apparatus is closed by a top wall having openings through which plants can grow with their roots enclosed in inverted cup-shaped barrier structures imbedded in a growing medium. At the time of the first planting there are multiple inverted cup-shaped barrier structures imbedded in the growing medium, but not all of them are provided with seedlings during the first planting. Water and air is provided in a reservoir below the growing medium which has means for assisting the transfer of water from the reservoir into the growing medium. Pre-selected plant nutrients (e.g., N, K) are appropriately placed on the growing medium at the time of the initial planting and are used over the course of time for plant growth during successive plantings. |
