Glass House Brands has received Good Agricultural and Collection Practice (GACP) certification for its Casitas and Padaro greenhouse facilities. This achievement marks a significant step toward the company's objective of supplying international and domestic medical cannabis markets.
Why it matters
The certification verifies that Glass House facilities meet stringent international safety and quality standards. This designation is essential for the company to begin exporting its greenhouse-grown flower to medical markets across Europe.
The GACP certification covers both the Casitas and Padaro farms, which together encompass over 500,000 square feet of greenhouse cannabis cultivation. The audit was conducted by Perry Johnson Registrars Food Safety, Inc.
