R 17

Reliable oyster mushroom yields on straw substrate

The «Р 17» mycelium by the "First Mushroom Company" (Pervaya Gribnaya Kompaniya) is a proven solution for commercial oyster mushroom cultivation. This strain is adapted to local climatic conditions and shows predictable growth dynamics when using straw as the primary substrate.

Production cycle and climate requirements

The key asset of this variety is the high rate of mycelial colonization. When technological parameters are met, the first harvest is ready for picking within 25–35 days after inoculation. This allows growers to optimize production cycles and plan deliveries to retail chains with high precision.

• Humidity levels: For high-quality fruiting bodies, it is critical to maintain humidity within the 85–95% range. Deviations can lead to drying of the mushroom caps, so an automated humidification system is a mandatory requirement when working with «Р 17».
• Substrate base: Using prepared straw provides an optimal structure for hyphal development. «Р 17» efficiently decomposes cellulose, reducing energy costs for substrate preparation compared to more demanding strains.

Practical advice for agricultural operations

By choosing «Р 17», you are focusing on an intensive business model. The strain demonstrates excellent fruiting synchronization, which significantly reduces labor costs during harvest as you pick mature clusters almost simultaneously. To achieve maximum marketable yield, we recommend strictly adhering to temperature breaks between flushes, ensuring the block does not overheat during the active mycelial growth phase.
