As part of the natural biological process, plants produce various metabolites. The amount of certain metabolites produced is important, especially during the growth phase of plants to be harvested in whole or in part. The production of metabolites is affected by the chemical environment within the plant, including the amount of CO.sub.2 and O.sub.2. The production of metabolites of interest can be controlled by measuring the amount of the metabolites being produced by the plant, and then adjusting the amount of CO.sub.2 and O.sub.2 available to the plant. These are adjusted by adjusting the amount of CO.sub.2 in water delivered to the leaves of the plant through foliar spraying and the amount of O.sub.2 in water delivered to the roots of the plant.

A flue gas extraction system provides extraction, collection, cooling, enriching and distributing flue gas from a vent stack of a stationary flue gas generator to carbon dioxide consuming crops, orchards, and other photosynthetic organisms. The collected flue gas is processed through the system to achieve optimal temperature, pressure, flowrate, water content and carbon dioxide concentration for application to plants for increasing plant productivity and sequestering the carbon dioxide. The gas distribution network may have one or more membrane modules which receive a low pressure gas mixture, where the membrane modules are utilized to enrich the CO2 concentration and to separate out a nitrogen rich component from the flue gas. Application of carbon dioxide may be supplemented by providing additional components to the plants which maintain a level of fertilization and irrigation suitable for the increased biomass and water utilization efficiency of the plants resulting from the increased intake of carbon dioxide.

A grow system. The system includes growing plants in grow modules that are individually moveable. The plants grow in trays where roots never touch the water supply. The plumbing to the grow modules is a low flow, one way flow continual drip system that is hands free. A mobile robot can navigate around a growspace, bring any grow module from one location to another, and perform growspace operations. The growspace is a control space with data source zones and a control space manager. The control space manager can collect data and control different variables across different data source zones in order to determine optimal policies and conditions for data source growth and generation.

A gravity-driven plant cultivation system includes: (a) a frame; (b) a plurality of stacked conveyor assemblies mounted to the frame, each conveyor assembly including at least one gravity conveyor extending along a sloped conveyor axis; and (c) a plurality of plant cultivation trays rollingly supported on each gravity conveyor and urged to translate along a corresponding conveyor axis via gravitational force. Each tray includes: (i) a tray body having at least one underside surface parallel and in engagement with the gravity conveyor for supporting the tray thereon; (ii) a plurality of plant cavities in the tray body for holding plants; and (iii) a nutrient chamber internal the tray body for holding plant nutrient solution for the plants. The nutrient chamber is bounded from below by a nutrient chamber bottom wall lying in a horizontal plane for maintaining a constant depth of the plant nutrient solution.

A plant cultivation tray for a gravity-driven plant cultivation system includes: (a) a tray body; (b) a plurality of plant cavities in and open to a top of the tray body for holding plants; (c) a nutrient chamber internal the tray body and in fluid communication with the plant cavities for holding plant nutrient solution. The nutrient chamber is bounded from below by a nutrient chamber bottom wall lying in a horizontal plane. The tray body has at least one underside surface for engagement with a sloped gravity conveyor to rollingly support the plant cultivation tray thereon. The at least one underside surface slopes downwards relative to the horizontal plane from a rear to a front of the tray body for maintaining a generally constant depth of the plant nutrient solution across the nutrient chamber bottom wall when the tray is supported on the gravity conveyor.
