100% Propane extraction | 80-90% THC Propane Hash Oil (PHO) and Butane Hash Oil (BHO) methods result in less toxic product and more terpene-rich infusion. PHO’s Propane extractions run at higher pressures, stripping different ratios of plant waxes and oils compared to butane which can deliver fewer residuals and higher levels of terpene preservation. Propane has a lower boiling point than butane, which allows for a lesser purging temperature for PHO and results from the buddery consistency instead of shatter. How to use: PHO can be smoked, vaporized or dabbed. PHO is great for vaporizer pens.
