Organic King Oyster Grow Kit XXL: grow king oysters at home
King oysters are firm, nutty in flavour and resemble porcini in texture. After harvest they keep longer than most other gourmet mushrooms. Our organic kit comes from our own production in Schleedorf and is ready to fruit.
How it works
- Place the kit in a humid spot at 15–20 °C.
- Cut an opening of about 5 cm above the white air filter.
- As soon as 4–5 cm mushrooms appear, remove the upper half of the foil.
- Keep it moist and harvest the whole flush at once.
Ideal conditions
- Temperature: 15–20 °C
- Humidity: around 90 %
- No waterlogging – pour off excess water
Good to know
- Store unopened in a cool, dry, frost-free place below 20 °C.
- For the next flush, 2–3 weeks of rest and a 4–5-hour water bath.
- No humid room? A large plastic bag over the kit helps.
All details, ideal conditions and answers to common questions are in our King Oyster grow kit guide.
