Abstract: A crop production system (100) for a controlled plant growing environment is provided. A subassembly comprises a guide portion that includes passive guides (104, 504, 904, 1004) radiating outward from a central portion (102, 502, 520, 911). Each passive guide may be separated from two adjacent passive guides by respective angles. Each passive guide has a first end proximal to the central portion and a second end distal to the central portion. Each passive guide is configured to guide plant growth modules (210). The plant growth modules are movable between the first end and the second end of each passive guide. An active guide (406, 907, 1007) causes the plant growth modules to travel in a first direction along the passive guides as the active guide is moved.

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.

Abstract: A plant support structure comprises segments, which each include at least one plant site. Each segment may have a first end and a second end. The first end may have a first opening, and the second end may slidably nest inside the first opening of an adjacent segment to enable an increase of distance therebetween. The first opening may be larger the second opening. Spacers or couplings between segments may be used to slide the segments apart. Each segment may include a path for a nutrient solution to flow to the at least one plant site in the segment.

Abstract: A controlled environment agriculture system that operates in connection with grow towers having overlapping funnels. The use of overlapping funnels functionally de-couples irrigation processes from tower conveyance.

Abstract: An arrangement and method are provided for weighing plant support structures that are travel along a conveyance line. A load bar includes connections to couple the load bar to a carrier, which is moveable along the conveyance line. The load bar receives ends of plant support structure hooks, and exerts a lateral force on the hooks as the load bar travels. A load cell includes a leading portion that is lower in height than a weighing portion of the load cell. Each hook raises as it travels onto the load cell. The relationship of the height of the weighing portion and the length of the hook end are arranged such that, as the hook end is raised, it remains engaged with the load bar so that the load bar continues to exert a lateral force on the hook as the load bar moves in the direction of travel.

Abstract: A plant plug holding unit is provided, the plant plug holding unit including at least one plant plug holder. The plant plug holding unit, which is configured to be inserted into a cut-out in a hydroponic tower face plate, includes an edge member that encircles the unit and is sealed to the rear surface of the front tower face. Each individual plant plug holder of the plant plug holding unit includes (i) a base member configured to support a plant plug and which extends rearward from the edge member and into the hydroponic tower cavity; (ii) a top shroud member that inhibits leakage as well as plug erosion; (iii) a pair of side members that maintain the position of the plant plug within the plug holder; and (iv) a plurality of open regions configured to promote water drainage from the plant plug.

Abstract: A hydroponic tower including a cavity defining a front tower surface and a rear inside surface, and further comprising a plant plug holder inserted within a cut-out defined in the front tower surface. The plant plug holder includes an edge member that encircles the holder's opening and which may be sealed to the front tower surface, and a base member configured to support a plant plug and which extends rearward from the edge member and into the cavity of the tower. The plug holder further includes a rear shroud top member and a pair of side members that maintain the position of the plant plug within the plug, holder such that the plant plug contacts the rear inside surface of the cavity when inserted into the plug holder.

Abstract: A tower opening apparatus is provided that is configured to simplify the opening of a multi-piece, hinged, hydroponic tower. The hydroponic tower opening apparatus utilizes a collection of static and continuously moving components (e.g., motor driven drive rollers, alignment rollers, stationary wedges, longitudinal ramps, etc.) to open a hydroponic tower as it passes through the apparatus. In particular, as the tower is driven through the opening apparatus, the fastener(s) holding the face plate(s) to the tower body is released by a wedge(s). After the fastener(s) is released, the face plate(s) is partially rotated about the tower body, thereby partially opening the tower cavity(s). Next a longitudinal ramp(s) continues to rotate the face plate(s) relative to the tower body, moving the face plate(s) to a fully open position.

Abstract: Embodiments of the present disclosure provide for weight measurement of grow towers and/or grow lines with grow towers disposed thereon. In various embodiments, compression type, tension type, and/or beam type load cells may be positioned at various locations within the apparatus to facilitate weight measurement. In one embodiment, a hook, which couples a grow tower to a grow line, includes a tension type load cell disposed between two portions of the hook. The load cell measures force applied thereto which can provide or be translated into a weight measurement.

Abstract: 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 reciprocating cam mechanism that provides a cost-efficient mechanism for conveying vertical grow towers in the controlled environment. The reciprocating cam mechanism can be arranged to increase the spacing of the grow towers as they are conveyed through the controlled environment to index the crops growing on the towers. The present disclosure also describes a tower shuttle mechanism that provides operational flexibility by decoupling the loading and unloading operations of the grow towers from the vertical farming structure and, therefore, allowing multiple grow towers to be extracted for harvesting in a batch process before loading new grow towers into the vertical farming structure in a separate process.

Abstract: Systems, methods, and computer-readable media are provided for controlling a ratio of carbon dioxide to oxygen in a grow space by removing O2 from the grow space, and, in some cases, adding supplemental CO2 to the grow space to achieve a desired ratio of CO2 to O2. Various approaches include filtering out oxygen or reacting O2 with a reactant to produce O2-reduced air; and removing air from the grow space, removing nitrogen from the removed air, and (a) separating out CO2 and returning the nitrogen and the CO2 to the grow space, or (b) adding supplemental CO2 and the nitrogen to the grow space. Another approach removes air from the grow space, separates out gasses including N2 and CO2, and returns the N2 or the CO2 to the grow space.
