Organic King Oyster Mushroom Spawn: for wood substrate
King oysters (Pleurotus eryngii) grow most reliably on wood substrate made of 90 % hardwood sawdust, 10 % wheat bran and 1–2 % gypsum. They also grow on straw, but with lower yields. We produce our organic spawn fresh in Schleedorf, Austria.
What you can use the spawn for
- Hardwood pellets in filter bags (recommended)
- Straw pellets
- Straw bales in the garden
Ideal conditions
- Colonisation: 20–24 °C, 10–15 days
- Fruiting initiation: 10–15 °C, 95–97 % humidity
- Fruiting: 15–21 °C, 85–90 % humidity
- Flushes: 1–2
How to use the grain spawn
- Keep it cool as soon as it arrives (ideally 1–3 °C).
- Plan around 10 % spawn relative to the moist substrate.
- Work cleanly and mix the spawn evenly into the cooled substrate.
- Let it colonise, then set it up for fruiting.
Tip from our practice: For thick stems, king oysters need little fresh air – but very high humidity during fruiting initiation.
