Glass House Brands is California's largest vertically integrated cannabis company, operating 5.5M+ sq ft of greenhouse canopy with brands including Glass H
# Glass House Brands California's largest cannabis greenhouse operation and one of the clearest examples of what vertical integration looks like when it's done right. Glass House Brands isn't just a cultivator — it's a full-stack cannabis company that controls the plant from seed to sale across some of the most fertile growing land in the state. ## Who They Are Founded around 2015 and headquartered in Carpinteria on the Santa Barbara coast, Glass House Brands runs massive greenhouse facilities where the marine climate is practically built for cannabis at scale. They went public on the Canadian Securities Exchange in 2021, making them one of the few vertically integrated CA operators with that level of market transparency. The team has been laser-focused on building out California before expanding nationally — a deliberate choice in a state this complex. ## What They Make Glass House operates a portfolio of sub-brands covering a wide range of price points and consumer occasions: Glass House Farms (premium sun-grown flower), PLUS (gummies and edibles), Allswell (value-tier pre-rolls and flower), Forbidden Flowers (mid-tier prerolls), FIELD (outdoor budget flower), and Mama Sue Wellness (CBD and wellness products). If you've bought legal cannabis in CA in the last few years, there's a real chance Glass House grew it — even if the label said something else. ## History The company spent years acquiring and converting former tomato and strawberry greenhouses in Carpinteria and Lompoc into cannabis operations. Their Lompoc facility is one of the largest cannabis greenhouse complexes in the world at over 5.5 million square feet of licensed canopy. That kind of scale is rare. That kind of scale in California is almost unheard of. ## Known For Volume without sacrificing consistency. Glass House moves more flower than almost anyone in the state while keeping quality benchmarks that hold across their brand tiers. Their PLUS edibles line is a fixture at dispensaries across CA, and Allswell has become a go-to value option for budget-conscious consumers who don't want to give up quality. ## Where to Find Them Available at hundreds of dispensaries across California. In LA, the Bay Area, Sacramento, San Diego — if there's a licensed store near you, there's a good chance at least one Glass House SKU is on the shelf. ## The High Rise Read Glass House is the kind of operation that makes outsiders think CA cannabis is conquerable at scale. They've built an actual company — with public reporting, real infrastructure, and a brand portfolio that covers every consumer from deal-hunter to connoisseur. The moves they're making in production capacity suggest they're positioning to be the backbone supplier of the California market for years.
