A cultivation floor system has a floor on which plant containers are to be placed. The system includes a watertight basin and a water-permeable structure in the basin, which structure has a permeable top cloth which forms the top side of the floor on which plant containers are placed. The structure includes one or more water-retaining layers. A watering installation supplies water so that water is available for the plants in the plant containers. A perforated film is placed between the permeable top cloth on the one hand and the one or more water-retaining layers on the other hand, which perforated film is made of impermeable film material which is provided with distributed perforations in such a manner that the film reduces the free evaporation surface for water from the one or more water-retaining layers.

Horticulture systems and methods including an air handling rack system comprising frame supply and return plenums, an input diffusion assembly physically supported by and fluidically coupled to the frame supply plenum, and a plant support tray assembly physically supported by and fluidically coupled to the frame return plenum. The input diffusion assembly is configured to direct a supply airflow flowing through the frame supply plenum downwardly from an underside thereof. The plant support tray assembly is positioned below the at least one input diffusion assembly to form an environmental cultivation chamber therebetween. The rack system is configured to direct the supply airflow through the environmental cultivation chamber from the input diffusion assembly to the plant support tray assembly past one or more plants positioned on a support side of the plant support tray assembly and into the frame return plenum as a return airflow.

An apparatus for use in indoor agriculture is provided, the apparatus comprising a plurality of elongate supports connected to at least one common manifold. Each elongate support within the plurality of elongate supports comprising: a main body having a first side; at least one inlet in fluid communication with the at least one common manifold; a plurality of outlets; and a channel within and extending along substantially the length of the main body between the at least one inlet and the plurality of outlets. The at least one common manifold is configured to allow gas to flow into the at least one inlets of the plurality of elongate supports, wherein the apparatus is configured such that during use, gas may flow from the common manifold to the at least one inlet of each elongate support within the plurality of elongate supports, through the channel of each elongate support and out of the plurality of outlets of each elongate support, such that a uniform flow of gas is provided adjacent the first side of the main body during use.

An apparatus for use in indoor agriculture is provided, the apparatus comprising a plurality of elongate supports (6) connected to at least one common manifold (8a, 8b). Each elongate support (6) within the plurality of elongate supports (6) comprising: a main body (12) having a first side; at least one inlet (16) in fluid communication with the at least one common manifold (8a, 8b); a plurality of outlets (14); and a channel within and extending along substantially the length of the main body (12) between the at least one inlet (16) and the plurality of outlets (14). The at least one common manifold (8a, 8b) is configured to allow gas to flow into the at least one inlet (16) of the plurality of elongate supports (6), wherein the apparatus is configured such that during use, gas may flow from the common manifold (8a, 8b) to the at least one inlet (16) of each elongate support (6) within the plurality of elongate supports (6), through the channel of each elongate support (6) and out of the plurality of outlets (14) of each elongate support (6), such that a uniform flow of gas is provided adjacent the first side of the main body (12) during use.

The invention is a customizable, slidable shelving and support apparati and system for supporting, storing and accessing horticultural and agricultural specimens within growing spaces, allowing growers to utilize the maximum amount of their linear horizontal and vertical grow space and service specific areas of the garden enterprise while also allowing for maximum workspace through the use of a table and track system that provides stackable options of multiple grow layers. A method of using this slidable shelving and support apparati and system is also included.

A system for applying CO.sub.2 gas to improve Cannabis and other crop production. A multi-stage system is disclosed including upstream, midstream, and downstream stages or subsystems. The upstream subsystem receives and stores gas, particularly CO2 gas. The midstream subsystem is communicatively connected to the upstream subsystem and to the downstream subsystem. 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 midstream subsystem.

A method of growing plants using a water-layer system, said method making use of a moveable container comprising a water-layer unit comprising a water tray, and a rectangular frame, said rectangular frame comprising two spaced apart wheel support beams, and support beams for supporting the water tray of the water-layer unit. The water-layer unit is provided with plants, and said plants are grown with access to the layer of water in the water tray. Furthermore, to grow plants more uniformly across the container, the wheel support beams have upper surface areas, and the support beams provide support areas for the water tray of the water-layer unit that in an empty first state are higher than the upper surface areas of the wheel support beams.
