A plant cultivation method includes providing a growth period and a rest period alternately. In the rest period, a dark period and a bright period is alternately provided. In the dark period, an intensity of light applied to a cultivation target plant is lower than a light intensity at a light compensation point. In the bright period, blue light whose wavelength is 400 nm to 500 nm is applied at an intensity that is lower than the light intensity at the light compensation point. A one-cycle time T of repetition of the dark period and the bright period is 2 μs to 500 μs. A duty ratio ΔT/T of a bright period time ΔT to the one-cycle time T is 20% or smaller. The blue light has a photosynthetic photon flux density of 0.001 μmol.Math.m.sup.−2.Math.s.sup.−1 to 4.0 μmol.Math.m.sup.−2.Math.s.sup.−1.

A method for eliminating pathogenic microbes from crops having foliage, comprising steps of drying the foliage and the pathogenic microbes thereon so that the pathogenic microbes on the dried foliage are in a state of growth dormancy and water absorbency readiness; and applying an ozone water solution, comprised of water with dissolved ozone, to the dried foliage, wherein the ozone water solution is absorbed by the dried pathogenic microbes which die upon absorbing the ozone water.

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 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.

The invention provides an improved system and method for a self-contained portable greenhouse, comprising a sun-light deprivation curtain system, and with a structural arrangement that integrates the fluid (liquid and air) distribution and dispensing for such plant life-support systems as water supply and irrigation, hydroponics water, nutrient and aeration, CO2 dosing, fuel (for power generation), forced-air ventilation, whereby its associated system components are miniaturized to a scale amenable for low voltage direct-current power, which are housed within the structure. The invention also provides a system architecture wherein the electrical interface infrastructure for connecting with electricity-producing resources—such as solar panels or wind turbines—is integrated into the portable greenhouse, as is the internal electrical distribution and direct-digital control for the plant life-support systems. The invention allows for multiple portable greenhouses to be interconnected along with other distribution energy resources (DER) in a DC microgrid arrangement.
