Mushroom Farming Business in India: Oyster vs Button, Cost, Setup and Profit (2026)

Last updated: October 2026

Mushrooms grow indoors, need very little land and give a crop in weeks, not months. You can start oyster mushroom farming in a single room with low investment, and later move to button mushroom with a climate-controlled unit. Demand is growing from hotels, restaurants, supermarkets and health-conscious families.

Oyster Mushroom Setup (Beginner)

• A clean room with windows or exhaust, racks or hanging ropes
• Straw (wheat or paddy), chopped and disinfected
• Spawn (mushroom seed) from a certified lab
• Polythene bags, a sprayer, and a humidifier or foggers
• A thermometer and hygrometer to check temperature and humidity

Growing Steps (Oyster)

1. Chop the straw and soak it in water with disinfectant (or hot water).
2. Drain to the right moisture.
3. Fill bags in layers of straw and spawn.
4. Keep the bags in the dark for spawn run (about 2–3 weeks) until white growth covers them.
5. Open or cut the bags, give light and maintain humidity with water spray.
6. Harvest in 2–3 flushes over the next few weeks.

Simple Profit Example (One Oyster Cycle)

1,000 bags, each yielding about 0.8 kg of fresh mushrooms over the cycle.

Output: 800 kg at ₹120/kg (wholesale)₹96,000 Bags, straw, spawn, chemicals (about ₹40/bag)– ₹40,000 Labour, power, transport– ₹15,000 Profit per cycle₹41,000

Indicative only. Running several staggered batches a year multiplies this. Selling dried oyster mushroom or value-added products (pickle, powder) increases margin.

Where to Sell

• Vegetable wholesalers and APMC markets
• Hotels, restaurants and cloud kitchens (fresh daily supply)
• Supermarkets and local vegetable vendors
• Direct to customers through WhatsApp groups in housing societies
• Dried mushroom and mushroom powder online

Important: Fresh mushrooms spoil in 2–3 days, so line up buyers before your first harvest.

Licences

• Growing fresh mushrooms usually needs no special licence. Check with your local gram panchayat or municipal body.
• For packed, dried or processed products: FSSAI registration or licence
• Udyam registration for loans and schemes

Training and Subsidy

• Training: Krishi Vigyan Kendras (KVKs), agricultural universities and ICAR's Directorate of Mushroom Research run short courses.
• Subsidy: State horticulture departments support mushroom units under the Mission for Integrated Development of Horticulture (MIDH). Rates differ by state.
• Loans: Mudra or PMEGP. See Government Schemes for MSMEs.

Common Mistakes

• Poor hygiene, which leads to contamination (green mould) and bag losses
• Buying cheap, uncertified spawn
• Growing before finding buyers

Common Questions Can I grow mushrooms at home?

Yes. Oyster mushrooms can be grown in a spare room for learning. Commercial scale needs a dedicated room with humidity control.

Which mushroom is most profitable?

Button sells the most in cities, but oyster is cheaper to start and less risky for beginners.

Where do I buy spawn?

From agricultural universities, KVKs or licensed spawn labs. Ask local growers for reliable sources.
