Variety description
10 August 2026
The strain is distinguished by a short production cycle of 60–75 days. Yield ranges from 16 to 30% of the raw substrate weight. The fleshy, dense mushrooms tolerate transportation and storage well, and delayed spore maturation reduces the risk of allergic reactions among personnel.
Cultivation does not require a temperature shock; a minor temperature fluctuation is sufficient. The color of the caps varies: at low temperatures, they take on a darker, gray shade, and at high temperatures, they become lighter. The strain is sensitive to the ventilation level in the room.
