These cannabis plant-starts are grown in greenhouses and on small family farms throughout Northern California. When ready, they’re harvested and transported to Santa Rosa for processing. The plant materials are tested for pesticides, molds, and bacteria. After passing inspection, the herb is dried, cured, and processed in a pharmaceutical-grade “clean” room. They use clean, high-pressure carbon dioxide at low temperatures to extract the cannabis oil. They employ proprietary methods to preserve the terpenes, that give each strain its distinctive smell and flavor. They package their cannabis oil in specially made cartridges that are designed to ensure easy flow and a reliable draw. They add absolutely no additives.
