Yellow Oyster Mushroom (Pleurotus citrinopileatus): A mushroom native to Asia.
Yellow oyster mushrooms are rich in protein, vitamins, and minerals, adding nutritional value to your meals. They also contain ergothioneine, a natural amino acid, as well as beta-glucans.
The yellow oyster mushroom has a unique citrusy flavor, with a more tender and delicate texture than its cousin, the gray oyster mushroom.
The yellow oyster mushroom is a tropical variety that naturally produces fruiting bodies when temperatures reach 18 to 25°C. It can withstand light frosts without any problems.
Off-season cultivation: We grow this variety mainly during the off-season (early fall through spring) because it thrives in warm weather.
Hardiness: This hardy variety is less susceptible to disease.
Caps: The caps measure between 3 and 7 cm in diameter, and their color ranges from bright yellow to pale yellow depending on growing conditions.
❄️ Storage of the mycelium: 1 month in the refrigerator (1–4°C).

Our commitment to quality:
We produce our mycelium in laboratory conditions, which ensures the purity of the strains and optimal quality.
We produce our mycelium using 100% organic methods, and all our products are certified "BE-BIO-01, Agriculture Belgique" by CERTISYS.

🌱 Growing conditions
Yellow oyster mushrooms require more heat than other varieties. They grow best at temperatures between 15 and 25°C. Maintain high humidity at the start of fruiting. Avoid drafts and stress to ensure a vibrant yellow color, which develops best in bright light.
🛠️ Growing media
For indoor cultivation: Use pasteurized straw, pasteurized sawdust, or other lignocellulosic materials.
We recommend ourorganic straw pellets, which work particularly well with oyster mushrooms; simply add 1 teaspoon of lime and 2 liters of cold water per kilogram of pellets.
Our sawdust-based growing medium, which is suitable for wood-eating plant varieties, will also work very well.
