Live resin
From Wiki Weed
A relatively new extraction process, reportedly developed by an old school grower known as “Kind Bill,” this process was impossible to do prior to the invention of commercial grade closed-loop butane extraction systems. Instead of using dry plant material as is the norm for BHO extractions, the live resin process used fresh frozen plants, which were harvested only hours earlier; this creates a product which has the terpene profile of the live plant rather than the dried flowers (terpenes degrade and change as the plant is dried).
