ABSTRACT:
An apparatus which includes a growing container in which plants are hydroponically grown on a support medium is disclosed. The growing container includes a plurality of openings in which seals are installed. The seals include holes through which the plants grow. When seeds are planted, a hollow tube is placed through the seal hole to maintain the seed in position. After the seed germinates, it grows through the tube. As continued growth expands the plant's stem to the size of the tube, the tube breaks apart and does not constrain future plant growth. Moreover, as the plant grows further, the seal hole expands to accommodate the plant stem. The seal surrounds and contacts the plant stem to reduce evaporation of nutrient solution from the growing container and to keep insects and contamination out of the growing container. A holding container is positioned above the growing container and coupled to the growing container through a manifold arrangement. The holding container may be quickly filled with a single, measured nutrient solution charge for the growing container. Then, a valve is opened, and the manifold arrangement slowly distributes the nutrient solution to the growing container where it is substantially absorbed by the support medium and wicked to the vicinity of the plant within the growing container.
