🌿 Harvest & Post-harvest
Solventless & Hash Concentrates made with water, ice, heat and pressure rather than with a solvent: ice water extraction and bubble hash, dry sift, and rosin pressed from flower, sift or hash. Mechanical separation, which is why the input quality sets the ceiling. Harvesting, Drying & Curing Harvest, drying and curing come at the very end of a crop and together take several weeks. They often have more effect on the final flower than most of the months of growing before them. This post covers three things: when to cut, why drying must be slow and even, and what happens to the flower during curing in a sealed jar. Extraction & Concentrates Solvent-based extraction and the concentrates it produces: ethanol, hydrocarbon and supercritical carbon dioxide, winterisation and distillation, and the safety and licensing questions that arrive with all of them. Solventless methods have their own sub-board.
