The Spore Genetics King Blue Oyster Liquid Culture Syringe is a premium option for cultivating the impressive Pleurotus ostreatus var. columbinus, commonly known as King Blue Oyster mushrooms. This robust and high-yielding strain is distinguished by its striking blue-gray caps and dense, meaty texture. King Blue Oysters grow in large clusters and are highly prized for their culinary versatility and unique appearance, making them a favorite among chefs and home cultivators alike.

This syringe contains a live, isolated biological sample that has been meticulously nurtured, tested, and expanded at Spore Genetics to ensure it is 100% contaminate-free.

Each purchase includes a sterile, individually packaged hypodermic needle for easy substrate injection.

King Blue Oyster mushrooms thrive on a variety of substrates, including sterilized hardwood logs, supplemented sawdust blocks, pasteurized straw, and other cellulose products. For those looking to experiment with growth mediums, petri dishes with malt extract agar and dextrose agar, along with spawn options such as rye berries, millet, oats, and corn are great choices.

This species requires cold temperatures to fruit successfully, with an incubation temperature of 70°F - 80°F over 12-14 days, followed by fruiting at 55°F - 65°F with humidity levels of 85% - 93%. King Blue Oysters also perform best in a high CO2 environment, where lower levels of carbon dioxide may affect both the color and shape of the resulting fruiting bodies. With a pinning time of 4-10 days and a total fruiting time of 14-18 days, King Blue Oyster mushrooms offer a rewarding cultivation experience for those with an intermediate level of expertise and a solid understanding of mushroom growing.
