RE:RE:RE:April 16th Geo, you can do 5 extraction methods yourself at home Butane, dry sift, water extraction, rosin (solventless), and ethanol. People will pay premium prices for rosin and live rosin which just uses heat and pressure. It will fetch a higher premium than Co2 extracts. Co2 is technically a green solvent but hippies don't like chemical names even if they're harmless.
