Deploy highly aggressive, isolated commercial genetics with our premium Maitake G2 Grain Spawn, sold per 1 kg unit. Produced as a second-generation (G2) grain spawn from our carefully maintained mother cultures, this spawn is selected specifically for rapid colonization, abundant cluster formation, excellent biological efficiency, and consistent yields. It is engineered to produce the distinctive layered rosettes, delicate overlapping fronds, and exceptional culinary quality that have made Maitake one of the world's most prized gourmet mushrooms.
Every batch is cultivated on premium, perfectly hydrated corn grain and sealed inside heavy-duty Type T Unicorn Bags. These industry-standard bags feature an integrated 0.2-micron gas exchange filter patch to optimize respiration while providing effective protection against competing molds and bacteria. Produced under strict sterile laboratory conditions, this fully colonized G2 grain spawn arrives contamination-screened and ready to inoculate your pasteurized or sterilized bulk substrate.
Order Notice and Freshness:
To ensure maximum viability and vigor, all grain spawn is prepared fresh to order. Please place your order or contact us 2–3 weeks prior to your planned inoculation date to allow sufficient time for sterilization, inoculation, and complete grain colonization.
Quality Guarantee:
We stand behind the cleanliness of our process. If biological contamination is present upon delivery, simply provide clear photographs within 24 hours of arrival and we will replace the grain spawn at no additional charge.
