We would like to welcome Rhiza Ranch, Oklahoma’s first farm to be Clean Green Certified®! 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. Over the last decade working in commercial cannabis production in Oregon and Colorado, we realized that soil fertility reigns supreme over conventional horticulture. That’s why our cannabis grows in living soil, is fed organic fertilizers, and is only treated with citric acid and beneficial bugs.
