Organic Oyster Mushroom Spawn: for straw, coffee grounds and wood
Grain spawn is the “seed” for your mushrooms: cereal grains fully colonised by mycelium. We produce our organic oyster mushroom spawn (Pleurotus ostreatus) fresh in Schleedorf, Austria. Oyster mushrooms grow on almost anything – from a straw bag indoors to a mushroom bed in the garden.
What you can use the spawn for
- Straw pellets in bags or tubular foil
- Soaked straw in a bucket
- Coffee grounds
- Straw bales and mushroom beds in the garden
- Hardwood pellets in filter bags
- Logs
Ideal conditions
- Colonisation: 20–24 °C, 14–22 days
- Fruiting initiation: 6–15 °C, 90–95 % humidity
- Fruiting: 5–20 °C, above 85 % humidity
- Flushes: 2–4
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: Oyster mushrooms prefer cool temperatures for fruiting. For hot summers, the summer oyster mushroom is the better choice.
