Blue Oyster (Pleurotus columbinus) Liquid Culture Syringe – 10ml / 10cc

Grow a Fast-Growing Gourmet Mushroom with Striking Color

Cultivate Blue Oyster mushrooms with our premium Grospore 10ml (10cc) liquid culture syringe. Known for their beautiful blue-gray caps, vigorous growth, and tender texture, Blue Oyster mushrooms are a popular choice among home growers, chefs, and mushroom enthusiasts. You will see this species listed both as Pleurotus columbinus and as Pleurotus ostreatus var. columbinus — they are the same mushroom, and it is also sold as Sky Blue Oyster.

As the mushrooms mature, their caps can transition from deeper blue-gray tones to softer shades of gray, creating attractive clusters with excellent culinary appeal.

Lab-Tested Liquid Culture for Reliable Growth

Our Grospore Blue Oyster Liquid Culture Syringe contains vigorous living mycelium, lab-tested and prepared in our ISO-certified cleanroom to support healthy colonization and dependable cultivation performance.

Each 10ml (10cc) syringe offers:

• Live Mycelium, Not Spores – This is a liquid culture (LC) syringe, not a spore syringe. There is no germination step, so colonization begins as soon as you inoculate.
• Lab-Tested & ISO Cleanroom Prepared – Every batch is lab-tested for purity and prepared in an ISO-certified cleanroom, so what reaches you is clean, contaminant-free and viable.
• Faster Colonization – Active mycelium helps promote efficient colonization compared with starting from spores.
• Convenient 10ml (10cc) Syringe – 10cc and 10ml are the same volume. Easy to use with appropriately prepared sterile growing media, grain spawn or agar.
• Vigorous Genetics – Cloned, isolated Pleurotus columbinus mycelium known for fast, aggressive growth.

How to Grow Blue Oyster Mushrooms

1. Prepare the Substrate – Straw, hardwood sawdust, and other appropriately prepared lignocellulosic materials are commonly used for Blue Oyster cultivation. The same syringe can also be used to inoculate sterilized grain spawn, grain jars or bags, or an agar plate.
2. Inoculate – Inject 2–3cc (2–3ml) per grain jar or bag through a self-healing injection port, using sterile technique in a still air box or in front of a laminar flow hood. Substrate may be sterilized or pasteurized.
3. Colonize – Allow the mycelium to fully colonize the substrate under suitable incubation conditions.
4. Initiate Fruiting – Once fully colonized, provide high humidity, indirect light, fresh-air exchange, and appropriate fruiting temperatures.
5. Harvest & Enjoy – Harvest clusters while the caps are still firm and tender for the best texture and culinary quality.
