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 Ganoderma lucidum culture for dense conk formation and strong lacquered surface development.\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. Reishi is a vigorous coloniser at warm temperatures and expands readily. Spawn to sterilized supplemented hardwood sawdust, oak for preference.\u003c\/p\u003e\n\u003ch2\u003eReishi Growing Conditions\u003c\/h2\u003e\n\u003cp\u003eReishi colonizes grain in 14 to 21 days at 77 to 86F, which is warmer than anything else in this collection except Pink Oyster, and it fruits warm too, from 70 to 82F. It is a long cycle species, often two to three months from pinning to harvest. The form you get is controlled entirely by your environment: high carbon dioxide and low light give you the antler form, while good fresh air exchange and light give you the flat lacquered conk. Both come from the same culture. It is a wood decay fungus and it wants hardwood, not straw.\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\u003eAntler versus conk form is controlled by CO2 and light\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.

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.\u003c\/p\u003e\n\u003cp\u003eBrowse the rest of the \u003ca href=\"https:\/\/www.out-grow.com\/collections\/mushroom-spawn\"\u003emushroom spawn collection\u003c\/a\u003e.\u003c\/p\u003e\n\u003cdiv class=\"og-internal-links\" style=\"margin-top:16px;padding:16px;background:#f7f4ef;border-top:2px solid #c8d4c4;font-family:'Source Serif 4',Georgia,serif;\"\u003e\n\u003ch3 style=\"font-family:'Libre Baskerville',serif;color:#1a2e1a;margin:0 0 10px;font-size:1.1rem;\"\u003eRelated Resources\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;display:grid;grid-template-columns:1fr 1fr;gap:6px 16px;\"\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/mushroom-spawn\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eMushroom Spawn Collection\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/pages\/mushroom-species\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eMushroom Species Library\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/pages\/reishi-ganoderma-lucidum\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eReishi (Ganoderma lucidum) Species Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/pages\/how-to-grow-reishi-mushrooms-ganoderma-lucidum\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eReishi (Ganoderma lucidum) Grow Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"og-internal-links\" style=\"margin-top:16px;padding:16px;background:#f7f4ef;border-top:2px solid #c8d4c4;font-family:'Source Serif 4',Georgia,serif;\"\u003e\n\u003ch3 style=\"font-family:'Libre Baskerville',serif;color:#1a2e1a;margin:0 0 10px;font-size:1.1rem;\"\u003eRelated Mushroom Spawn\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;display:grid;grid-template-columns:1fr 1fr;gap:6px 16px;\"\u003e\n\u003cli\u003e\u003ca href=\"\/products\/maitake-mushroom-spawn\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eMaitake Mushroom Spawn\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/antler-reishi-mushroom-spawn\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eAntler Reishi Mushroom Spawn\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/gold-oyster-mushroom-spawn\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eGolden Oyster Mushroom Spawn\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pink-oyster-mushroom-spawn\" style=\"color:#4a6e42;text-decoration:underline;\"\u003ePink Oyster Mushroom Spawn\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Out-Grow","offers":[{"title":"Default Title","offer_id":50439881752769,"sku":"OG-SPAWN-QT-REISHI","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/7287\/5201\/files\/reishi-mushroom-grain-spawn-quart-jar.webp?v=1785009002","url":"https:\/\/www.out-grow.com\/products\/reishi-mushroom-spawn","provider":"Out Grow","version":"1.0","type":"link"}
