Haywood Mushrooms / Strains

Culture lines we develop and cultivate.

Each strain below is isolated on agar, screened for vigor, and selected for real-world growing conditions in our own lab. Most are grain spawn ready to ship now; a few are still in development. Specs are working targets from our own cultivation, not marketing numbers.
