Carbon Dioxide (or CO2) Extraction
Also known as supercritical carbon dioxide (or CO2) extraction, CO2 extraction is a technique that freezes and compresses CO2 to its supercritical state then passes the cold CO2 liquefied gas through cannabis, pulling all of the essential cannabinoids, terpene oils and waxes out of the plant material into collection receptacles. The method leaves no residue and produces an amber-colored oil which can be vaporized in a number of ways.
Carbon Dioxide (or CO2) for Cultivation
It is the addition of carbon dioxide (or CO2) to cannabis gardens to quicken the plant development and pack weight onto their buds, increasing the crop’s yield. Cannabis growers operating a closed system use CO2 generators to increase concentrations of carbon dioxide to around 800 - 1,500 Parts-Per-Million (PPM). The use of CO2 for cultivation, however, is more effective if the plants are fed with more hydroponic nutrients, light, and water.
