Each Lab Solventless cartridge is made using premium flower, harvested by hand and freshly frozen to preserve all of the qualities of this amazing plant. The flower is then submerged in a freezing water bath and agitated, which results in all the cannabinoid-rich trichomes being released from the plant. This cannabinoid-rich mixture is then pressed with heat and force to produce the highest quality, most sought-after form of concentrate available. No chemicals or solvents are used in this extraction.
