A commercial button mushroom unit is part civil construction, part refrigeration, part agronomy. Getting all three right is what separates a profitable unit from a stalled one.
Unit layout
Production rooms, spawn handling, compost yard, pre-wetting bunkers, packing & cold storage — laid out for hygiene zoning and one-way flow.
Climate & refrigeration
Each production room runs cycles of spawn run, case run, pinning and cropping with specific temperature, humidity and CO₂ targets. Refrigeration + humidification + fresh-air systems are sized together.
Capex & manpower
Indicative capex ranges ₹40 Lakh–₹1.5 Cr depending on rooms, automation and compost scope. Manpower includes a unit manager, 4–8 trained workers, and harvesting staff.
