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.
Grain spawnA cool-weather oyster with steel-blue young caps that fade to silver-grey. Prized for firm texture and clean flavor, and a strong performer through the colder months of the growing calendar.
Grain spawnA tropical oyster that fruits in vivid coral clusters and moves fast — often the quickest way from inoculation to harvest. Loves warmth, rewards humidity, and makes an unmistakable market display.
Grain spawnThe commercial standard for a reason — aggressive colonization, forgiving across substrates, and thick, meaty caps. A dependable base for any production room and the easiest strain to keep contamination-free.
In developmentA gourmet and functional favorite that fruits as dense, cascading white icicles. Selected for vigorous mycelium and clean fruiting — more technique-sensitive than oysters, and worth it.
Shiitake fruiting block
— to be supplied
The classic hardwood mushroom — deep umami, firm texture, and a loyal market. Slower to colonize and fruit than oysters, with a browning-then-fruiting cycle that rewards patient, controlled conditions.
