North Sun Golden Oyster Liquid Culture – 10 ml Syringe
Pleurotus citrinopileatus
The North Sun golden oyster is a dependable commercial strain prized for its sturdy fruiting bodies—denser and less brittle than most golden oyster varieties. When given adequate humidity, it rewards the grower with big, showy flushes of vibrant mushrooms ranging from bright yellow to deep golden hues. Its forgiving nature and visual appeal make it a popular choice for both market growers and home cultivators.
Culture format:
This 10 ml syringe contains actively growing Pleurotus citrinopileatus mycelium suspended in a nutrient-rich medium. It’s beginner-friendly and perfect for inoculating grain jars, grain bags, or other prepared substrates. Each syringe is sealed in a sterile sleeve and includes a sterile 16 g needle and alcohol wipe.
Lab handling and best practices:
Refrigerate immediately – Shelf life is ~2 months when chilled.
Shake before use to evenly distribute the mycelium.
Inoculate through a self-healing injection port for best results.
Maintain sterile technique – A still air box or flow hood will help avoid contamination.
Needle reuse – Flame-sterilize before and after each use.
Golden oysters thrive in high humidity and reward attentive care with striking flushes that stand out in any grow room or market display.

Pleurotus eryngii
The Stephen King trumpet is a Japanese-origin commercial strain known for producing big, meaty fruit bodies with a rich, earthy aroma and savory flavor. While it prefers cooler fruiting conditions, it’s notably tolerant of warmer temperatures, making it a flexible choice for year-round cultivation in many climates. Expect 0.75–1.5 lbs. on the first flush from a 5 lb. supplemented sawdust block, with additional smaller flushes to follow.

Lab handling and best practices:

If you’re looking for a hardy, high-yield oyster strain that doesn’t mind a temperature swing, the Harbor Blue from Pennsylvania is a solid choice.

On a 5 lb. supplemented sawdust block, expect 1–2 lbs. on the first flush, with good follow-ups. It will also fruit on sterilized straw if you prefer a lower-cost substrate.
