Growing Marijuana is an Art, Knowing Marijuana is a Science

You could say we’ve earned our Masters in marijuana. Through our decades of studying, experimenting, and cultivating, we have developed a deep knowledge and passion for this powerful plant. We have found that when used in the right way, marijuana has the power to not only improve your health, but your quality of life as well.


Our unique skillset lies somewhere between art and science: a keen eye for quality marijuana, the expertise to find the right strains, and the knowledge of how each one can help the human body in unique ways. We believe the marijuana industry needs the quality and care of true artisanship, supported by an intimate understanding of the human body.

My parents met at a knock on the door.
the San Francisco 1980 census
I was later born.
They say that’s rare.
Being born in SF
I know some others.
I ran through the Mission as a kid
Lucky Pork. Le Boulangerie.
Foxy Lady.
Playing at Dolores park. Trick or treating up and down hills.
I was a known character.
Running errands with my babysitter in tow
14th through 25th streets.
We played street hockey, jail tag,
hopped across roofs of apartment buildings,
slammed together like painted ladies.
My mother allowed me to run,
RUN to the store for milk.
Hom sat at the corner store. Hamzi was across the street.
Hom had fresh vegetables. Hamzi had liquor.
Good schools. A few languages. Travel. That’s me. Lil’ o’ Chicky.
