Green House Seed Company

Green House Seed Company is a long-running cannabis genetics and seed business best known for breeding, marketing, and selling cannabis seeds and related strain genetics. The company appears to operate primarily as a commercial seed bank and branded cannabis genetics business rather than as a drug-development biotech, pharmaceutical, or healthcare company. Its products are consumer cannabis seed strains, including feminized, autoflowering, and CBD-oriented varieties, and it markets globally through e-commerce and distribution channels. The company is widely associated with founder Arjan Roskam and the Strain Hunters brand, and is recognized in the cannabis sector for award-winning strains and brand longevity since the 1980s.
