Black Oyster SING-001 Commercial Liquid Culture (200ml)

Black Oyster SING-001 Commercial Liquid Culture (200ml)

Scale your black oyster sing-001 (Pleurotus ostreatus) production with this 200ml commercial liquid culture jar. SING-001 is a tropical black oyster isolate sourced from Southeast Asia that produces dramatically dark caps and thrives in warm, humid conditions. This jar gives you lab-isolated genetics in a format designed for repeated sterile draws across large production batches. Made in Canada at our CFIA-licensed facility in Brantford, Ontario.

What's Included

• One 200ml mason jar with live black oyster sing-001 mycelium in sterile honey-water medium
• Self-healing injection port for clean, repeated culture draws
• Synthetic filter cap for continuous gas exchange
• Lab-isolated Pleurotus ostreatus genetics

How to Use

Draw culture through the self-healing injection port using a sterile syringe. One 200ml jar provides enough culture to inoculate a full production run of grain jars or grow bags.

• Wipe the injection port with isopropyl alcohol before every draw
• Use a sterile 18-gauge needle and syringe
• Inject 2-5ml per grain jar or spawn bag
• Swirl the jar gently before drawing to ensure even mycelium distribution

Species Profile

Why Commercial Size

The 200ml jar format lets you maintain genetic consistency across your entire spawn production line. One jar replaces dozens of individual syringes, and the self-healing injection port allows repeated draws without opening the jar — keeping contamination risk low and throughput high.

Build your production workflow with our grain spawn and commercial grow bags.
