Mushroom Farming in India — A to Z Complete Guide
Mushroom farming is growing edible mushrooms on a prepared substrate inside a humidity- and temperature-controlled room. This A to Z guide covers which variety to grow, the space and climate you need, what a farm costs, the 60-day crop cycle, yield, profit and subsidy — whether you start with one oyster bag or a commercial 4-room unit.
What is mushroom farming?
Mushroom farming is the controlled cultivation of edible fungi — most commonly button (Agaricus bisporus), oyster (Pleurotus) and milky (Calocybe indica) mushrooms — on pasteurised compost or straw substrate inside rooms held at a fixed temperature, 85-90% humidity and controlled CO₂. In India a crop cycle runs about 60 days from spawning to final flush, a climate-controlled room yields roughly 18-22 kg per square metre per cycle, and setup ranges from about ₹2 lakh for a small oyster unit to ₹30.7-43.2 lakh (ex-GST) for a commercial four-room button farm.
Which Mushroom Should You Farm?
Variety decides your climate control, substrate and market. Compare the three commercially proven options in India.
| Factor | Button | Oyster | Milky |
|---|---|---|---|
| Growing temperature | 16-18°C cropping | 20-30°C | 30-35°C |
| Substrate | Phase-2 wheat straw compost | Chopped straw / sawdust | Pasteurised paddy straw |
| Crop cycle | 55-60 days | 35-45 days | 45-55 days |
| Yield | 18-22 kg / sq m per cycle | 8-12 kg / sq m per cycle | 6-10 kg / sq m per cycle |
| Climate control | Mandatory (PUF + HVAC) | Optional in mild climates | Light control, summer friendly |
| Best suited to | Commercial, year-round supply | First-time and low-budget growers | Hot regions, summer cropping |
What Does a Mushroom Farm Cost?
Indicative all-in setup bands. GST and transportation are extra, and any additional client requirement is treated as extra.
Home / trial unit
₹50,000 – ₹2 lakh
Oyster bags in a shed or spare room. Learn the cycle before investing in infrastructure.
Starter farm (1 room)
₹6.6 – 11.7 lakh
One PUF-insulated 18×30 or 18×40 ft room with racking, HVAC and humidification.
Commercial (4 rooms)
₹30.7 – 43.2 lakh
Four production rooms with staggered cropping for continuous weekly supply.
Integrated unit
₹49.7 lakh – ₹1 Cr+
Production rooms plus own compost unit, cold room and packing area.
Approx. figures for planning only — see the project cost calculators or the mushroom farming subsidy guide for scheme-wise assistance.
Where Do You Sell the Crop?
Local mandi / wholesale
₹80 – 120 per kg
Fastest offtake in volume, lowest realisation. Needs same-day despatch.
Retail & kirana supply
₹150 – 200 per kg
200 g punnets to shops and supermarkets. Better margin, needs cold chain and packing.
Hotels, restaurants & caterers
₹120 – 180 per kg
Steady weekly orders with consistent grading and reliable delivery days.
Dried & value-added
₹700 – 1,200 per kg dried
Roughly 10 kg fresh gives 1 kg dried. Extends shelf life and smooths price swings.

What You'll Learn
Choosing the Right Mushroom
Button, Oyster, or Milky — which suits your climate and investment level?
Climate Requirements
Temperature (16-18°C for button, 20-30°C for oyster), humidity (85-90%), and CO₂ control essentials.
Grow Room Infrastructure
PUF-insulated rooms with AHU, evaporative cooling, and fresh air dampers for year-round production.
Compost Preparation
Phase-I composting in aerated bunkers (6 days) + Phase-II pasteurization (6 days), 15-16 days from pre-wetting to spawning, for pathogen-free substrate.
Spawning & Spawn Run
Grain spawn at 0.6-0.7% rate, thorough mixing, and 12-16 day incubation at 24-25°C in dark conditions.
Disease & Pest Management
Prevention-first approach: hygiene protocols, green/brown mould identification, and biological controls.
Harvesting & Post-Harvest
Picking at button stage (2.5-4.5 cm), cold chain at 2-4°C, and packaging for 5-7 day shelf life.
Economics & ROI
Investment of ₹6.6-43.2 lakh, production of 2,000-6,000 kg/cycle, payback in 20-34 months.
6 Steps to Start Mushroom Farming
Learn
Take a 5-7 day training at ICAR-DMR Solan or a state agriculture university, and check the current fee with the institute.
Plan
Choose mushroom type, room count, and budget. Use our Design Generator for a free project layout.
Build
Set up PUF-insulated grow rooms with climate control. Start with 1-2 rooms (18×30 or 18×40 ft).
Source
Get Phase-2 compost from a certified supplier or build your own composting unit.
Grow
Follow our SOPs for spawning, casing, fruiting, and harvesting. First crop in 30-37 days.
Sell
Sell fresh at mandi/wholesale (₹80-120/kg), retail (₹150-200/kg), or process for dried mushrooms.
