Pink Oyster Liquid Culture Syringe (10cc)

About Pink Oyster

Pink Oyster (Pleurotus djamor) is the fastest-fruiting mushroom we offer and the only one that produces vibrant salmon-pink caps that look almost too beautiful to eat. Native to tropical and subtropical regions, this species thrives in heat that would stall other oysters, exploding from inoculation to harvest in as little as two to three weeks. The caps are ruffled and delicate with a slightly more brittle texture than other oysters — they're a market showstopper and a great choice for growers running warm grow tents or summer greenhouses.

Growing Notes

• Difficulty: Beginner
• Preferred substrate: Straw, hardwood sawdust, supplemented sawdust blocks
• Fruiting temperature: 70–85°F
• Colonization speed: Fast
• Special considerations: Loves heat and humidity — ideal for summer growing or heated grow tents. Fruits aggressively and short shelf life once harvested, so plan to sell or eat the same day. Color deepens with cooler night-time drops within the range.

Culinary Uses

Pink Oysters have a delicate, almost seafood-like flavor with a tender, slightly chewy texture that some compare to calamari. They cook down significantly and develop a beautiful caramelized edge when pan-seared. Best enjoyed fresh — sauté quickly with garlic and butter, batter-fry as a calamari substitute, or fold into tacos. Note that the striking pink color fades to a soft salmon when cooked.

Usage Instructions

• Sanitize your work area, tools, and contact surfaces before handling.
• Prepare grain, substrate, agar, or grow kits according to your standard operating procedures.
• Introduce the liquid culture using sterile or near-sterile technique (e.g., in front of a flow hood or still-air box when applicable).
• Maintain species-appropriate incubation and fruiting conditions for temperature, humidity, and fresh air exchange.

Shelf Life & Storage

Store refrigerated at 34–39°F (1–4°C) away from direct sunlight. Under proper storage, typical shelf life is 3–6 months unopened. Always visually inspect for contamination, damage, or off-odors before use.

Quality & COA

Each batch is prepared using standardized procedures and test-inoculated on appropriate media before release. These internal checks act as our in-house Certificate of Analysis (COA) to confirm viability and cleanliness at the time of packaging.

How to Use This Liquid Culture

1. Sterilize the injection port on your grain bag with an alcohol prep pad.
2. Shake the syringe vigorously for 10-15 seconds to disperse the mycelium evenly.
3. Inject 1-2cc of liquid culture through the self-healing injection port of your grain bag. Less is more — 1cc is usually plenty.
4. Seal and incubate the bag at 70-75°F in a clean, dark space.
5. Wait for colonization — white mycelium will begin spreading through the grain within 2-4 weeks.

Temperature & Timeline: Colonization typically takes 2-4 weeks at 70-75°F. Warmer is not better — temperatures above 80°F increase contamination risk.

Signs of Success: You'll see white, fluffy mycelium spreading outward from injection points. The grain will become covered in a uniform white coating when fully colonized.

Next Steps: Once the grain is fully colonized, transfer it to a bulk substrate or introduce fruiting conditions, depending on your setup.

Common Mistake: Injecting too much liquid culture does not speed up colonization — it wastes culture and can introduce excess moisture that encourages contamination. Stick to 1-2cc per bag.
