Mushroom Farm Engineering Data
The sizing methods behind every MushroomWale BOQ — cooling tonnage, insulation, racking, compost capacity, airflow and cycle yields. Published openly so you can check any quote, ours or anyone else's.
What engineering decides a mushroom farm's output?
Five numbers set a commercial mushroom farm's performance: cooling tonnage per room (about 1 TR per 100–120 sq ft), PUF envelope thickness (60 mm common walls, 80 mm external, 80–110 mm roof), rack tier geometry, compost tonnage per filling, and CO₂ held under 1,000 ppm through cropping. Get these right and the third flush stays profitable.

Mushroom Grow Room Tonnage (TR) Calculation
Cooling tonnage for a button mushroom grow room: TR per sq ft, compost respiration load, room volume and the TR table for 18×30 to 18×70 ft rooms.
Read the mushroom grow room tonnage (tr) calculation methodPUF Panel Thickness for Mushroom Growing Rooms
PUF panel thickness for mushroom grow rooms: 60 mm common walls, 80 mm external walls, 80/110 mm roof, plus density, PPGL coating and area method.

MS growing rack design for mushroom farms: tier spacing, aisle width, rack height, MS angle and jali quantities, and how layout limits room capacity.

Sizing a Phase-1 bunker and Phase-2 pasteurisation tunnel: compost per grow room, tonnes per cycle, aeration rate and cycle-day planning.

CO₂ targets by growth stage, fresh-air damper sizing, duct throw and humidity interaction — the airflow method behind MushroomWale grow rooms.

Button mushroom cropping cycle day-by-day: flush timing, yield per bag and per room, cycles per year and labour planning for commercial farms.

Recommended plan summary
Climate unit per room: Daikin 8 TR (~28 kW Outdoor Unit)
2× Outdoor Unit (4 HP ea., R32 3ph HMT) + 1× Indoor Unit (HMT Dual-Circuit Evap, 550mm fan)
Compost planning: ~80–96 tonnes of Phase-III compost per filling, staggered across rooms so tunnel turns stay continuous.
Indicative engineering estimate only — not a price quotation. Final sizing depends on site conditions, climate zone, ceiling height and grower practice. GST and transportation are extra; any additional client requirement is charged extra.
