Golden Sun Oyster Commercial Liquid Culture (200ml)

Golden Sun Oyster Commercial Liquid Culture (200ml)

Scale your golden sun oyster (Pleurotus citrinopileatus also known as Golden Oyster Yellow Oyster) production with this 200ml commercial liquid culture jar. Golden sun oyster is a warm-weather tropical species that produces bright yellow clusters with a delicate, cashew-like flavor. 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 golden sun oyster 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 citrinopileatus 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

Golden sun oyster is a warm-weather tropical species that produces bright yellow clusters with a delicate, cashew-like flavor. It's one of the most visually striking oyster mushrooms and commands premium pricing at markets. It requires warmer fruiting temperatures than other oysters and colonizes quickly on a variety of substrates.

Growing Parameters

• Scientific name: Pleurotus citrinopileatus
• Fruiting temperature: warm (18-28°C)
• Recommended substrate: straw, 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.
