Variety description

10 August 2026

The strain is characterized by an even distribution of harvest flushes, which ensures a prolonged harvesting period. Yield is 20–28 kg/m². Fruit bodies are white, medium-sized, with a round, firm cap 4–6 cm in diameter, dense texture, and a solid stem.

Cultivation is carried out using an intensive method in enclosed spaces. Optimal environmental parameters include an air temperature of 18 °C, humidity of 85–90%, and a CO₂ level of 1200–1500 ppm. The substrate requires a moisture content of 68–70%, nitrogen content of 2–2.4%, and pH 7–7.5. The period for full substrate colonization takes 12–14 days.
