Start your mushroom cultivation with our premium Reishi Grain Spawn, available in approximately 1.5 kg units. Reishi (Ganoderma lingzhi) is produced as second-generation (G2) grain spawn from carefully selected commercial fruiting genetics chosen for vigorous mycelial growth, reliable colonization, abundant fruiting, excellent biological efficiency, and consistent yields. Available as Traditional Reishi or Antler Reishi, 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. Reishi is renowned for its glossy reddish-brown fruiting bodies, woody texture, and long history of cultivation as one of the world's most recognized functional mushrooms. Whether selecting Traditional Reishi or Antler Reishi, 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.
