Organic Oyster Mushroom Grain spawn

🍄 GRAIN SPAWN OF PLEUROTUS PULMONARIUS: Pleurotus pulmonarius, a close relative of the oyster mushroom (*P. ostreatus*), is distinguished by its more meaty texture and its ability to be cultivated year-round.
💪 AGGRESSIVENESS AND RESILIENCE: A particularly vigorous mycelium that grows quickly and is resistant to contamination, making it ideal for the uniform and reliable colonization of your substrates.
🍽️ SUPERIOR FLAVOR: Firm, dense, and meaty texture, with an excellent, slightly woody flavor. More refined than the oyster mushroom and perfect for gourmet dishes such as sautéed or grilled dishes.
🌍 LOCALLY SOURCED AND ORGANIC: Mycelium produced in Belgium, certified organic "BE-BIO-01" by Certisys.

Italian oyster mushroom (Pleurotus pulmonarius)

This variety of oyster mushroom is easy to grow and is suitable for both beginners and professionals. Its vigorous mycelium significantly reduces the risk of contamination. It is often called the summer oyster mushroom because this variety tolerates high temperatures better than regular oyster mushrooms. However, it can also be grown in winter, at which time the mushrooms have better flavor and keep longer. With a very rapid growth cycle, incubation generally takes 10 to 15 days, followed by fruiting and predictable fruiting .

The caps measure between 3 and 7 cm, with colors ranging from light brown to dark brown, depending on growing conditions. The stems are generally smaller than those of Pleurotus ostreatus and tend to grow individually rather than in clusters.

❄️ Storage of the mycelium: 1 month in the refrigerator.

Our commitment to quality:

We produce our mycelium in laboratory conditions, thereby ensuring the purity of the strains and optimal quality.

Our mycelium is 100% organic and certified "BE-BIO-01, Agriculture Belgique" by CERTISYS.

🌱 Growing conditions

This variety is particularly heat-tolerant, making it ideal for warm climates or summer conditions. However, it can be grown year-round, with improved shelf life when stored in cool conditions. fruiting extremely quickly, and harvests follow one after another in a predictable pattern. It is recommended to harvest the mushrooms while they are young for better shelf life and texture.

🛠️ 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.

📊 Growing conditions

Inoculation: 5–10% grains per unit of moist substrate

Phase	Temperature	Duration	Humidity	Light	CO2	Fresh air
Incubation	20–29°C	10–20 days. Colonization occurs much more quickly on straw than on sawdust.	-	n/a	n/a	n/a
Formation of primordial cells	10–20°C	3–5 days	95–100%	1,000–2,000 lux	500–800 ppm	5 to 10 cubic feet per hour
fruiting	10–30°C	3–8 days, depending on the temperature	85–95%	1,000–2,000 lux	500–800 ppm	5 to 10 cubic feet per hour
