Growth is very fast, typically colonizing a 100mm plate in approximately 3-5 days at an optimal temperature of 72–79°F. Note: this vigorous strain can quickly overgrow plates and hide contamination under thick aerial mycelium — use frequent edge transfers and avoid letting plates over-colonize or dry between uses.\u003c\/p\u003e\n\u003ch3\u003eMushroom Culture Use\u003c\/h3\u003e\n\u003cp\u003eMushroom cultures, typically on MEA culture plates, are used to grow and preserve mycelium. In most cases, sterile transfers of agar wedges from this plate are used to inoculate fresh culture media or sterilized grain spawn.\u003c\/p\u003e\n\u003ch3\u003eMushroom Culture Storage\u003c\/h3\u003e\n\u003cp\u003eYour mushroom culture can be wrapped in parafilm and stored at normal room temps, in a sealed baggie, for up to 6 months. Out-Grow recommends you replate your mushroom culture every 6 months to ensure longevity of your purchase.\u003c\/p\u003e\n\u003cp\u003eStore fully colonized plates at 35–43°F in darkness, sealed with moderate humidity. Plan to transfer every 1-3 months using young edge mycelium for new working cultures, with master plates and slants maintained for long-term stability.\u003c\/p\u003e\n\u003ch3\u003eMushroom Cultures Are Made to Order\u003c\/h3\u003e\n\u003cp\u003eAll mushroom culture plates are made to order. Once your order is received, Out-Grow will inoculate your plate within 1-3 days. Your mushroom culture will then be incubated in our mycology lab for approximately 7-14 days, or until clean healthy mycelium has been verified by our mycologist. Once verified, your order will be shipped promptly. Please allow an additional week for your mushroom culture to fully colonize upon arrival, as colonization time varies by species.\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=\"\/pages\/grey-oyster-mushroom-pleurotus-ostreatus\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eGrey Oyster Mushroom (Pleurotus ostreatus) Species Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/pages\/how-to-grow-grey-oyster-mushrooms-pleurotus-ostreatus\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eGrey Oyster Mushroom (Pleurotus ostreatus) Grow Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/grey-oyster-mushroom-pleurotus-ostreatus\" style=\"color:#4a6e42;text-decoration:underline;\"\u003eGrey Oyster Mushroom (Pleurotus ostreatus) Liquid Culture\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Out-Grow","offers":[{"title":"Default Title","offer_id":50046514987201,"sku":null,"price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/7287\/5201\/files\/Mushroom_Culture_Plate.png?v=1773334304","url":"https:\/\/www.out-grow.com\/products\/grey-oyster-mushroom-pleurotus-ostreatus-mushroom-culture","provider":"Out Grow","version":"1.0","type":"link"}
