MMXX, our namesake strain is the culmination of decades of careful and selective breeding and is the embodiment of our brand itself. MMXX has enormous colas and mind-blowing potency, she is exploding with irritatingly sticky trichomes. The earthy fuel and spicy dank terpenes reminiscent of the misty mountains in which she was born, come through in both aroma and flavor. This is true California, true Emerald Triangle and true Twenty20.

To bring you the next generation (F2) of MMXX we carried out one of our biggest hunts on record. After sprouting over 400 MMXX F1 seeds and selecting through each we found the MMXX #18 and MMXX #48 to be the perfect pair for the job. The MMXX #18 is the frostiest plant since Sour Snow herself and carries a rich, full, classic funk that lingers even after you’ve left the garden. And the MMXX #48 swells to the day of harvest, providing ample surface area for mature resin production. Both selections produce an unbelievably viscous resin packed into capitate-stalked heads for hashers’ dream plants. This is the next generation of MMXX. This is the next generation of Twenty20.
