Start your mushroom cultivation with our premium Golden Oyster Grain Spawn, available in approximately 1.5 kg units. Golden Oyster (Pleurotus citrinopileatus) is produced as second-generation (G2) grain spawn from carefully selected commercial fruiting genetics chosen for rapid colonization, vigorous cluster formation, excellent biological efficiency, and consistent yields. Each bag contains fully colonized premium corn grain, providing a vigorous inoculum ready for expansion onto pasteurized or sterilized bulk substrates.
Every grain spawn bag is prepared under strict sterile laboratory conditions and inspected before shipment to ensure vigorous, contamination-free colonization. Golden Oyster is prized for its brilliant golden-yellow clusters, delicate texture, mild nutty flavor, and rapid growth, making it one of the most visually striking gourmet mushrooms to cultivate. Grain spawn is ideal for inoculating a wide variety of hardwood-based bulk substrates for reliable mushroom production.
Freshly Prepared:
To ensure maximum viability and vigor, every grain spawn bag is prepared fresh to order. Please allow approximately 2–3 weeks for grain preparation, sterilization, inoculation, complete colonization, quality inspection, and packaging before shipment.
