UMMA Sonoma is a family-driven cultivation team based in Santa Rosa, California, operating two state-of-the-art indoor facilities built around precision, consistency, and respect for the plant.

Our roots trace back to the Prop 215 era, where years of hands-on experience shaped the foundation of our craft.

We combine clean mineral inputs with thoughtfully selected organic amendments to support plant health and bring out each cultivar's full expression. Our precision cultivation practices maintain consistency throughout the growing cycle, resulting in vibrant, terpene-rich flower with exceptional quality and character.

Beyond production, we conduct in-house breeding and extensive pheno hunting to continually refine our genetic library—selecting cultivars for exceptional expression, quality, and performance within our environment.
