Organic Summer Oyster Mushroom Spawn: for warm temperatures
The summer oyster mushroom (Pleurotus pulmonarius) feels most at home in warm conditions, making it perfect for summer or warm rooms. It has a finer texture and milder flavour than the classic oyster mushroom. We produce our organic spawn fresh in Schleedorf, Austria.
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: 15–20 °C, 90–95 % humidity
- Fruiting: 11–28 °C, above 85 % humidity
- Flushes: 2–3
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: No cold shock needed – to start fruiting, simply scratch the colonised substrate.
