Do you grow your own cannabis?

Yes, all of our cannabis products are grown in California by multi-generational farmers who have an extensive history of growing. Please visit our Cannabis overview page for more detail.

Greenbrier operates 8 acres of temperature-controlled greenhouses in the Santa Barbara Coastal Valley. In our humble opinion, the climate and weather there is the most conducive for greenhouse growing in the State of California.

The USDA regulates the organic certification process. Every fruit, vegetable or other consumable product must meet a specific set of guidelines to be labeled “certified organic.” Greenbrier has been growing under the USDA guidelines for other crops. Because cannabis is federally illegal, the USDA cannot regulate any nutrients or pesticides, and cannot give it the USDA stamp of approval. No one should be claiming otherwise. However, we do practice organic growing methods and use organic soil for all of our products under the Greenbrier Holdings umbrella.

We laboratory test for potency, microbials, metals, bacteria and pesticides. We test our plants for their cannabinoid profile and to ensure they are free of pesticides and microbials. Our products go through the multifaceted testing implemented by the state of California.  Once we get state approval, our product is ready for distribution.
