Large Mushroom Growing Chamber
The Edible Fungus Cultivation Warehouse (also known as an industrial mushroom growing warehouse or smart mushroom facility) is a fully climate-controlled, industrial-grade cultivation facility designed for medium and large edible fungus producers. Built on a standardized factory structure and equipped with an IoT cluster management system, it delivers fully automatic and precise regulation of temperature, humidity, lighting, CO₂ concentration and ventilation, supports simultaneous zoned production of multiple fungal species, and achieves an annual capacity of several hundred tonnes.
Exterior View
Modern edible fungus cultivation warehouse — a white steel-structure industrial building with a centralized rooftop ventilation system and an outdoor digital environmental display screen, surrounded by green fields and equipped with a logistics loading dock.
Interior Production Workshop
Inside the cultivation warehouse — arrays of 3 m high vertical cultivation racks densely packed with mushroom grow bags, with enoki, white beech (buna-shimeji) and oyster mushrooms cultivated simultaneously. Blue-red LED supplementary light strips provide tier-by-tier illumination, while the ultrasonic misting system sprays to maintain humidity.
Harvesting Operations
Harvesting stage — workers in clean, dust-free garments carry out manual picking. Digital sensors on the cultivation racks display real-time readings of 18.5°C temperature, 92% humidity and 850 ppm CO₂, with full environmental data records kept for every batch of mushrooms.
