Maitake Mushroom (Grifola frondosa) Grain Master For sale is a 1-quart jar of Maitake Mushroom Spawn. This is a generation 1 grain master mushroom spawn jar used for expansion of isolate mycelium, optimized for spawn run times and bio efficiency. Out Grow has isolated this Maitake culture for its ability to knot and form a primordium reliably, which is the step where most Maitake grows fail. What a G1 Grain Master Is A grain master is a jar of fully colonized grain made to be transferred, not consumed. Generation 1 means the mycelium in this jar came directly from one of our agar plates rather than from another bag of grain, so it sits one step from the culture library instead of three or four. That matters because every transfer is another opportunity for contamination to ride along, and because a G1 jar still has the full expansion runway ahead of it. One quart can seed several more quarts of sterile grain, and those can seed your bulk substrate. How to Use This Jar Rest, break, recover, transfer. Maitake is slow on grain and slower on the block. Spawn to sterilized supplemented hardwood sawdust, preferably oak, and settle in for a long cycle. Maitake Growing Conditions Maitake is a rewarding species for growers ready to move past the fast oysters. Grain colonizes in 21 to 30 days at 70 to 75F, then the block goes through a browning and knotting phase where the surface darkens and forms a dense primordium before fruiting at 55 to 65F. That knotting stage is the species working normally and is worth waiting out. Supplemented hardwood sawdust, oak for preference, gives the best results. Expect a longer cycle than an oyster and a considerably deeper flavour at the end of it. Spawn run 70 to 75F Grain colonization 21 to 30+ days Fruiting temperature 55 to 65F Substrates Supplemented hardwood sawdust, preferably oak Difficulty Advanced Season Cool season Also known as Hen of the Woods Note Long browning and knotting phase is normal Storage and Shelf Life Refrigerate at 35 to 40F. Warm to room temperature for a day before transferring. Do not freeze. In the Kitchen Also called Hen of the Woods. Tear the fronds by hand rather than cutting, and roast hard until the edges crisp. It has the deepest flavour of anything in this collection. Guarantee and Live Shipping Every jar is inspected before it leaves our lab and guaranteed to arrive alive and contamination free. If it does not, photograph the jar sealed and unopened and contact us within 48 hours of delivery for a replacement or refund. Live spawn is temperature sensitive, so we hold shipments during extreme heat and cold rather than sending something that will not survive the trip. Browse the rest of the mushroom spawn collection.
