About Oyster Mushroom Cultivation in India
Oyster mushroom (Pleurotus ostreatus) is the fastest-cycle commercial mushroom in India and the most common entry-point variety for first-time growers. The cultivation cycle runs 35 to 45 days from spawning to first flush, which means a single 18 ft by 30 ft module can deliver 8 to 10 cycles per year — significantly more turns than button mushroom.
Substrate is pasteurised paddy or wheat straw — abundant and inexpensive across North India. No casing soil is required, and the HVAC load is roughly half that of button mushroom because fruiting tolerates 22 to 25 deg C. This combination of low capex (Rs 6 to 9 lakh per module), short cycles, and forgiving climate makes oyster the preferred SKU for B2C farmer markets, rural FPO clusters, and PMEGP / NABARD-funded micro-projects.
MushroomWale builds turnkey oyster modules with PPGL-coated PUF panels, Daikin 6 TR HVAC, hot-water pasteurisation tanks, and bag-hanging racks — engineered for round-the-year production in Uttar Pradesh, Bihar, Haryana, Punjab and Madhya Pradesh.
