Abstract: A tower closing apparatus is provided that is configured to simplify the closing of a multi-piece, hinged hydroponic tower. The hydroponic tower closing apparatus utilizes a collection of static and continuously moving components (e.g., motor driven drive rollers, alignment rollers, tower body alignment rollers, face plate manipulation rollers, face closing rollers, etc.) to close a hydroponic tower as it passes through the apparatus. In particular, as the tower is driven through the closing apparatus, a series of face plate manipulation rollers gradually rotate the face plate(s) relative to the tower body, moving the face plate(s) from a fully open position to a partially closed position. Next a series of face closing rollers continue to rotate the face plate(s) from the partially closed position to the fully closed position, forcing the fasteners to latch the face plate(s) into position.

Abstract: An irrigation system for a vertical farming structure having vertical grow towers and associated conveyance mechanisms for moving the vertical grow towers through a controlled environment, while being exposed to controlled conditions, such as lighting, airflow, humidity and nutritional support. The present disclosure describes a grow tower conveyance system that moves vertically-oriented grow towers to select positions along a grow line. An irrigation line having apertures at the select positions provides aqueous nutrient solution to the grow towers, while a gutter structure captures excess solution. In a closed loop system, the excess solution returns to a recirculation tank. The present disclosure provides a dual pump system for effectively and efficiently removing excess nutrient solution from the gutter structure.

Abstract: A tower catch mechanism that facilitates loading of vertical grow towers in a vertical farming structure having associated conveyance mechanisms for moving the vertical grow towers through a controlled environment, while being exposed to controlled conditions, such as lighting, airflow, humidity and nutritional support. The present disclosure describes a load conveyance mechanism that transfers grow towers to a loading position where grow towers are loaded onto a select grow line. Each grow line may include a grow tower conveyance system that moves vertically-oriented grow towers to select positions along a grow line. The system may include a tower catch mechanism that registers grow towers in position at the loading position for insertion into a select grow line. In some implementations, the tower catch mechanism can be integrated into other structures of the vertical farming system, such as a gutter basin corresponding to a select grow line.

Abstract: A multi-piece hydroponic tower is provided which utilizes separate tower body and face plate components that are hingeably coupled together, thereby simplifying tower construction as well as tower maintenance. In addition to the hinge, the tower face plate(s) is held in place with a latch, e.g., a snap-fit fastener. A V-shaped groove may be included on either side of the tower, the grooves increasing the efficiency of delivering water and nutrients to the plants via the narrowed rear cavity wall(s). The V-shaped grooves may also be used as an alignment aid when coupling planters, harvesters, or other equipment to the tower.

Abstract: A lighting assembly is provided that is configured for use with a hydroponic farm, preferably a hydroponic farm utilizing horizontal racks. The light assembly includes one or more LED boards affixed to a thermally conductive mounting fixture. The number and location of the LED boards which are mounted to the fixture is primarily dependent upon the size and layout of the hydroponic racks within the hydroponic farming facility. A light shield, which surrounds the LED boards and the mounting fixture, extends the entire length of the light assembly. The light shield is sealed to both light assembly end caps, thereby providing a completely sealed lighting unit.
