  • Patent number: 12144353
    Abstract: A system for applying CO2 gas to improve Cannabis 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.

  • Patent number: 10999975
    Abstract: A system, device and method for delivering CO2 or other gases to plants in fields, orchards, vineyards and the like. A stake with a windbreak structure and gaseous emitters on the upwind side creates a leeward wind eddy surrounding a plant, such as an orchards sapling. This establishes and maintains a gaseous microclimate beneficial to the plant. The device delivers CO2 gas to a plant in an agricultural field, orchard, grove, orchard of the like. The device includes an elongated base adapted to be adjustably placed on the ground a predetermined distance from the plant, upwind of the plant. A wind foil is adjustably connected to the base along its elongated length. The wind foil has a curvilinear geometry with a first face having a generally convex configuration, and a second face having a generally concave configuration. An emitter assembly is disposed on the second face of the wind foil. A gas supply conduit is communicatively connected to the emitter and adapted to be connected to a gas supply.

  • Patent number: 10894105
    Abstract: A system and method of abating air pollution and stimulating crop growth. A reagent is introduced to a crop canopy to neutralize air pollutants within said canopy, wherein the reagent induces an oxidation-reduction chemical reaction with the air pollution present throughout the acreage of crops, and by means of the reaction effectually neutralizes the harmful effects of the air pollutants on the crops. The reagent is diluted using a venturi valve or other means. The flow rate of said reagent is regulated using an electronic control unit, based on data collected from at least one type of sensor in the canopy that is in communication with the control unit.

  • Patent number: 10599169
    Abstract: A system and method of optimizing Carbon Dioxide (CO2) delivery to crops during high-temperature periods. The method of facilitating plant growth includes the steps of (a) determining the wilting temperature of a set of plants; (b) measuring the ambient temperature of the plants; (c) supplying CO2 gas to the plants when the ambient temperature reaches a predetermined temperature point prior to the wilting temperature of the set of plants; and (d) continuing to supply CO2 gas to the plants until the ambient temperature of the set of plants falls below the predetermined temperature point, and then discontinuing supplying CO2 gas to the plants. Temperature of the plants is measured by a temperature sensor continuously monitoring the ambient temperature of the plants. A CO2 gas applicator disposed near the plants supplies CO2. The CO2 gas applicator is connected to a controller that is connected to a CO2 gas source.
