This is a generation 1 grain master mushroom spawn jar used for expansion of isolate mycelium, optimized for spawn run times and bio efficiency.\u003c\/p\u003e\n\u003cp\u003eOut Grow has isolated this culture as Ganoderma multipileum, a distinct tropical species and not the Ganoderma lucidum most sellers list under the reishi name. It was selected for its strong branching antler habit.\u003c\/p\u003e\n\n\u003ch2\u003eWhat a G1 Grain Master Is\u003c\/h2\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\n\u003ch2\u003eHow to Use This Jar\u003c\/h2\u003e\n\u003cp\u003eRest, break, recover, transfer. Handle as you would any warm season wood decay species. Spawn to sterilized supplemented hardwood sawdust and restrict fresh air exchange during fruiting to drive the antler form.\u003c\/p\u003e\n\u003ch2\u003eAntler Reishi Growing Conditions\u003c\/h2\u003e\n\u003cp\u003eGanoderma multipileum is a separate species from Ganoderma lucidum, a distinction that most of the market gets wrong because many Asian strains sold as lucidum were reclassified as multipileum. It colonizes grain at 77 to 86F and fruits warm. Held under high carbon dioxide and low light it produces the branching red lacquered antler form this culture is named for, which is more dramatic than a flat conk and considerably more interesting to grow. It is a long cycle species like any Ganoderma, so plan in months.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpawn run\u003c\/th\u003e\n\u003ctd\u003e77 to 86F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGrain colonization\u003c\/th\u003e\n\u003ctd\u003e14 to 21 days\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFruiting temperature\u003c\/th\u003e\n\u003ctd\u003e70 to 82F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSubstrates\u003c\/th\u003e\n\u003ctd\u003eSupplemented hardwood sawdust, preferably oak\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDifficulty\u003c\/th\u003e\n\u003ctd\u003eIntermediate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSeason\u003c\/th\u003e\n\u003ctd\u003eWarm season\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNote\u003c\/th\u003e\n\u003ctd\u003eA distinct species from Ganoderma lucidum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eStorage and Shelf Life\u003c\/h2\u003e\n\u003cp\u003eRefrigerate at 35 to 40F.
