Some implementations of the invention can be used to create a horizontal-to-vertical interface between a vertical grow structure that includes vertical grow towers and associated conveyance mechanisms for moving the vertical grow towers through a controlled environment, and a central processing system that processes (for example, harvests, cleans, transplants, etc.) the grow towers.

Abstract: Harvesting systems for an automated crop production system for controlled environment agriculture that includes vertical grow towers or other grow structures. Some implementations of the invention include a two-stage grouping mechanism that increases the amount of plants or crops harvested from a grow tower. Some implementations of the invention allow for harvesting of grow towers having grow sites on opposing faces.

Abstract: Mechanisms that facilitate location and alignment of grow towers for one or more processing operations. In one implementation, the alignment mechanism comprises a track including an alignment feature and one or more engagement actuators. The alignment feature is configured to engage features of a track-contacting face of a grow tower. The engagement actuators press the grow tower against the track, causing the alignment feature to engage the grow tower and align it along the track to facilitate processing operations.

Abstract: Automated transplanter assemblies and systems. For example, the disclosure sets forth a plug holder and assembly adapted to transplant plugs into tight-fitting plug holders. The disclosure also conveys a transplanter assembly useful in transplant operations where a plug holder is oriented at a non-perpendicular angle to the surface of a grow tower or other structure that contains the plug holder.

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: Facility layouts and configurations for an automated crop production system for controlled environment agriculture. In particular implementations, the core of the facility comprises a controlled growth environment and a central processing system. The controlled growth environment includes systems for exposing crops housed in modules, such as grow towers, to controlled environmental conditions. The central processing system may include various stations and functionality both for preparing crop-bearing modules to he inserted in the controlled growth environment for harvesting crops from the crop-bearing modules after they have been extracted from the controlled growth environment, and for cleaning or washing crop-hearing modules for re-use.

Abstract: An automated crop production system for controlled environment agriculture that includes a horizontal-to-vertical grow tower interface between a vertical grow structure that includes vertical grow towers and associated conveyance mechanisms for moving the vertical grow towers through a controlled environment, and a processing system that performs one or more processing operations—such as harvesting, cleaning and/or transplanting—on the grow towers in a substantially horizontal orientation. The present disclosure also describes an automated crop production system for controlled environment agriculture that selectively routes grow towers through various processing stages of an automated crop production system.

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 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 an irrigation system that provides aqueous nutrient solution to the grow towers.

Abstract: Systems, methods and computer-readable media are provided for controlling environmental conditions to control latent and sensible loads in a plant grow chamber. The density of plant receptacles in the grow chamber is such that, when plants are held in the plurality of plant receptacles, evapotranspiration contributes to the latent load so that the latent load exceeds a sensible load, resulting in evapotranspirative cooling. This shift in the energy balance allows for greater energy savings, as compared with conventional indoor farms that focus on removing heat from the growth environment. Environmental conditions may be controlled to achieved desired conditions, such as the optimum ratio of harvest weight yield to energy consumption under given constraints.

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.
