King Trumpet Commercial Liquid Culture (200ml)

King Trumpet Commercial Liquid Culture (200ml)

Scale your king trumpet (Pleurotus eryngii also known as King Oyster Royal Trumpet) production with this 200ml commercial liquid culture jar. King trumpet is one of the most commercially valuable gourmet mushrooms. 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 king trumpet 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 eryngii 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

King trumpet is one of the most commercially valuable gourmet mushrooms. It produces thick, meaty stems with small caps, and has a dense, almost scallop-like texture when seared. Unlike other oysters, it fruits best from the top of supplemented sawdust blocks rather than from side cuts. It requires specific fruiting conditions but rewards patient growers with high-value yields.

Growing Parameters

• Scientific name: Pleurotus eryngii
• Fruiting temperature: cool (12-18°C)
• Recommended substrate: supplemented hardwood sawdust, masters mix

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.
