Start your mushroom cultivation with our premium Paddy Straw Grain Spawn, available in approximately 1.5 kg units. Paddy Straw (Volvariella volvacea) is produced as second-generation (G2) grain spawn from carefully selected commercial fruiting genetics chosen for vigorous mycelial growth, rapid colonization, reliable fruiting, 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. Paddy Straw is a fast-growing warm-weather gourmet mushroom prized for its delicate flavor, tender texture, and excellent productivity in tropical and subtropical climates. It is widely cultivated throughout Asia and performs best under higher fruiting temperatures than most gourmet mushroom species. Grain spawn is ideal for inoculating a variety of suitable 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.
