Glass House Brands Achieves GACP Certification for California Farms

LONG BEACH – Glass House Brands Inc. has secured third-party certification under the PJRFSI Cannabis Safety Standard for Good Agricultural and Collection Practice (GACP) across its primary Southern California cultivation infrastructure. The certification confirms the sites meet defined international safety and quality standards for Cannabis cultivation. Additionally, this regulatory development positions the company to align its large-scale farming footprint with internationally recognized supply requirements.

GHB earned formal certification following audits conducted by Perry Johnson Registrars Food Safety, Inc., covering its Casitas and Padaro greenhouse locations in Carpinteria, CA. The two farms together cover more than half a million square feet of greenhouse space and rank among the larger GACP-certified Cannabis operations in the country.

Glass House stated it intends to supply greenhouse-grown flower to medical markets once U.S. federal law and the rules of importing countries permit export. The company continues discussions with state and federal agencies on California export pathways and maintains talks with domestic and international partners.

The audit framework verifies that agricultural operations meet strict benchmarks governing plant handling, facility hygiene, chemical safety, and batch traceability. GACP compliance acts as an operational foundation for agricultural inputs entering regulated medical Cannabis supply chains worldwide. For American Cannabis operators, obtaining external audit validation establishes standardized quality control protocols across primary harvest processes. The verification addresses technical requirements routinely demanded by institutional buyers operating in medical jurisdictions.

The certification offers clear technical advantages for the producer’s commercial trajectory:

• Standardized procedures minimize production variance and lower risk profiles during primary drying, trimming, and storage.
• Compliance creates the necessary technical framework for future export activity as trade policies evolve.
• European medical Cannabis programs [notably in Germany, Switzerland, and the United Kingdom] require strict agricultural oversight for raw plant imports.
• Third-party verification strengthens commercial trust with domestic institutional distributors seeking consistent quality.

Adopting internationally recognized agricultural standards reflects an operational shift among large-scale domestic producers. While state regulatory structures handle local market oversight, high-volume operators like GHB are increasingly building operational capabilities designed to interface with broader global supply networks.

Meeting GACP criteria demands capital investment in standardized quality management systems, comprehensive documentation, and ongoing facility maintenance. Executing these protocols across significant acreage demonstrates operational maturity and establishes a predictable supply base capable of satisfying medical Cannabis standards.

The GACP approvals add a formal quality credential to GHB’s large-scale California greenhouse platform, bridging the gap between commercial agricultural output and pharmaceutical-grade supply requirements. The practical value of the certification will rest on the pace of federal and international regulatory change that would allow actual product movement.
