Start your mushroom cultivation with our premium Shiitake Grain Spawn, available in approximately 1.5 kg units. Shiitake (Lentinula edodes), available as Donko or Koshin, is produced as second-generation (G2) grain spawn from carefully selected commercial fruiting genetics chosen for vigorous mycelial growth, reliable colonization, 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. Shiitake is one of the world's most widely cultivated gourmet mushrooms, prized for its rich umami flavor, firm texture, attractive brown caps, and outstanding culinary versatility. Whether selecting Donko or Koshin, growers can expect dependable cultivation performance from carefully maintained commercial fruiting genetics. Grain spawn is ideal for inoculating 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.
