Greenhouses designed for optimized thermal control are provided, incorporating various elements for controlling the temperature and air quality in the greenhouse. The greenhouses are configured with structural insulation in the roof, walls, and floor of the greenhouse which use particular materials, such as concrete, glass or polycarbonate, and design implementations for thermal control of the greenhouse. The airflow and environment in the greenhouse is also managed by providing air circulation systems controlling the fresh air flow and temperature and humidity of the air in the greenhouse.

A conveyor system (4, 5) moves vertical poles (2) in an agricultural facility between a growing area (20) and a workstation (W). Each pole carries plant growing containers (3) at multiple levels (H1-H9). An irrigation reservoir (30) may be mounted atop each pole. Irrigation lines (31-33) from the reservoir may be individually metered (35) at each level to compensate for differing water pressure with height. Sensors (40) in the reservoir and at each level of the poles may provide a controller (36) with data input. The controller may impose different growing conditions in different areas of the facility, including vertically different grow areas (20A, 20B), and controls pole movements and locations selectively to provide a sequence of poles at the workstation ready to harvest on a demand schedule. The workstation may have multiple heights (W1, W2, W3) for tall poles that increase plant density per facility footprint.

A plant grow unit (10) includes a body (12) that bounds an interior area (14). Access to the interior area is controlled by a door (18). The interior area houses a plurality of grow lights (50) which are selectively operated in response to at least one control circuit (96) to provide suitable illumination and radiation for growing selected plants. Shelves (46, 48) are selectively positionable for supporting plants thereon. A plurality of sensors and devices in the interior area are operated responsive to the control circuit to maintain desired conditions for plant growth within the interior area and to indicate detected conditions.

The invention relates to a ventilation system and method for promoting growth of a plant. The system comprises an air inlet provided at a first height from a defined floor level, an air outlet, fluidly connected to the inlet, an air moving device for moving air from the inlet to the outlet, and a plant growing surface, provided at a second height, being higher than the first height, for accommodating growing plants, wherein the air outlet is provided at a third height, being higher than the second height. The inventive concept is based on the inventors' realization that improved growing conditions can be provided by transporting CO.sub.2 from the bottom of a lower level in a greenhouse to a higher level.

A symbiotic agricultural system includes a fungi growing environment and a plant growing environment. The symbiotic agricultural system includes a control system that controls airflow from the fungi growing environment to the plant growing environment based on a carbon dioxide level in the plant growing environment.

A plant growing system comprising a growing panel and a porous air hose coupled to the growing panel. The growing panel includes a plurality of openings for receiving a plurality of plant receptacles. The plurality of openings are arranged in a plurality of parallel lines on the growing panel, and the porous air hose extends along the growing panel between at least two of the parallel lines.

A system and adjustable apparatus for applying CO.sub.2 gas to improve Cannabis production. The system includes upstream and downstream stages or subsystems. The upstream subsystem receives and stores gas, particularly CO2 gas. It monitors the environment of the downstream subsystem, determines when and how to apply gas to plants growing in the downstream system, acquires gas stored in the upstream subsystem, and distributes it to the downstream system. It also has various monitoring, command and control, management, and reporting features. The downstream subsystem includes one or more plant growth areas or plots, gas distribution means, such as gas conduits, tubes or lines from the midstream subsystem, and the high efficiency, adjustable gas applicator, and various sensing and monitoring devices communicatively connected to the upstream subsystem. Also disclosed are odor mitigation and humidity control features.
