SPARC is the long-trusted source for the highest-quality cannabis. Our cannabis products in San Francisco are sustainably grown on our Sonoma County estate in fully organic, biodynamic fields and greenhouses, using only natural sunlight. SPARC began in 1998 as a trailblazer in medical cannabis, and today continues to originate and propagate many of the industry’s most rigorous quality-control practices. For those who benefit from medical cannabis and those who responsibly enjoy adult-use cannabis, SPARC is committed to advancing the standards of how cannabis is cultivated, packaged and retailed industry-wide, and being a force for good in the neighborhoods and communities we call home.
