Learn more about Us

Rhiza’s Ranch-grown cannabis is the highest quality available

The closet to “Organic” that cannabis can get.

We use best practices using natural pesticides and control methods which are maintained under organically based regulations. The Clean Green Certified® program ensures we are legally compliant at the state level.

Recognized as having the highest level of standards in the world. Chris Van Hook founded one of only 84 fully accredited USDA National Organic Program companies globally. We are honored to be a part of this reputable industry. 



We're passionate about soil.

The foundation of a healthy plant starts with the soil. Our custom soil blend is a permanent living entity on the ranch, and its year-over-year care is our key to premium, organically grown cannabis. We prioritize soil fertility by cultivating a community of bacteria and fungi nurtured by compost teas and organic amendments. In turn, the soil provides all the nutrition to sustain plant growth and optimize plant yield. As with wine, our soil imparts a unique terpene profile reconnecting cannabis consumers with nature.

Our roots run deep

Rhiza Ranch is a family owned and operated farm in Harrah, OK. As the first certified Clean Green cannabis grower in Oklahoma, we strive to give patients access to clean, responsibly grown cannabis.
