A harvester for brassicas, the harvester being movable along a plant row and comprising an endless conveyor orientated in the direction of the plant row, the conveyor being of generally tubular form defined by opposed rows of arcuate conveyor fingers movable from an open condition in which free ends of the opposed fingers are spaced so as to define a generally tubular configuration which is open at one side to a closed condition in which the free ends of the opposed fingers are adjacent to define a generally closed tubular configuration, the conveyor having an upper run and a lower run, the conveyor being configured at its forward end portion so that the fingers are in their open condition during transition from the upper run to the lower run and move downwardly onto a plant to be harvested so as to move foliage away from the plant head and to allow the plant head to enter the interior of the conveyor through the open side, with the fingers then moving to a closed condition to thereby capture the plant head with the interior of the conveyor, the harvester further comprising means for cutting the plant stem whereby the plant head severed from the remainder of the plant can be carried by the conveyor for discharge from the conveyor when the fingers by which the head has been retained are returned to their open condition.

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.
