How to Grow Button Mushrooms in India?
Button mushroom (Agaricus bisporus) is grown in eight stages: Phase-I composting (Day 0-9 on the slab and in bunkers, core 70-78°C), Phase-II pasteurisation and conditioning in a tunnel (Day 9-15: 58-60°C for 6-8 hours, then 45-50°C; the compost cycle is 15-16 days), spawning, spawn run (about 14 days, air 22-24°C), casing (4-5 cm), case run (7-10 days at 24-25°C), airing down to pin (17-18°C) and cropping over three flushes at 16-18°C. A 18×40 ft room holds 1,600 bags and gives about 3,200 kg a crop, six crops a year.

8-Phase Growing Process
Compost Preparation (Phase-I)
Wheat straw, chicken manure, bran, gypsum and urea are wetted and mixed on the slab, then aerated in bunkers and turned between them.
Pasteurisation & Conditioning (Phase-II)
In a sealed tunnel, never above 62°C. Conditioned with fresh air until ammonia is under 10 ppm, then cooled to 25°C.
Spawning
Grain spawn at 0.6% (0.5-0.75%) of wet compost weight, filled into bags at 90-100 kg per m² of bed.
Spawn Run
Room closed and air recirculated. CO₂ of 5,000-15,000 ppm helps the mycelium through the compost.
Casing
A 4-5 cm layer of pasteurised casing soil (pH 7.2-7.5) goes over the colonised compost.
Case Run
Mycelium grows up into the casing. CO₂ 5,000-10,000 ppm; water in light split doses of 1.0-1.5 L/m².
Airing Down & Pinning
Fresh air on to pull CO₂ under 1,000 ppm. Pins form as white dots on the casing.
Harvesting (3 flushes)
Flushes about a week apart, roughly 50%, 30% and 20% of the crop. Pick at 3-4 cm cap; keep RH under 92%.
