Mushroom farming is emerging as a profitable home-based agribusiness in India. With minimal space and investment, anyone can grow mushrooms at home and earn a good income.
In this guide, we will take you through everything, from choosing the right mushroom variety to harvesting and selling.
Why Mushroom Farming at Home Is a Good Idea
Mushrooms are highly nutritious, rich in protein, vitamins, and minerals, and have a growing demand in urban and semi-urban areas. Advantages of home-based mushroom farming:
- Requires low space and minimal investment.
- Fast-growing crop: Ready to harvest in 25–40 days.
- High market demand in restaurants, hotels, and local markets.
- Eco-friendly: Uses agricultural waste like paddy straw or wheat straw.
- Year-round production possible.
- Export potential for premium varieties.
- Environmentally sustainable practice.
- No pesticides or chemicals needed and,
- Can be done alongside other occupations.
Step by Step Process to Mushroom Farming
Step1: Choose the Right Type of Mushroom
The first step is to select the type of mushroom suitable for home cultivation in India:
- Select a mushroom type suited to your local climate.
- Button mushrooms for cooler climates.
- Oyster and milky mushrooms for warmer areas.
- Button mushrooms are common for home farming.
| Mushroom Type | Ideal for Beginners | Growing Method | Approx. Harvest Time |
|---|---|---|---|
| Oyster (Pleurotus spp.) | Yes | Bags/Trays | 25–30 days |
| Button (Agaricus bisporus) | Moderate | Trays/Compost beds | 30–40 days |
| Shiitake | Advanced | Logs | 60–90 days |
Step 2: Choose Your Location
Indoor Setup Requirements:
- Well-ventilated room or shed
- Temperature control capability
- Protection from direct sunlight
- Easy access to water supply
- Minimum 100 sq ft for small-scale operation
Outdoor Setup Options:
- Covered terrace or balcony
- Greenhouse or polytunnel
- Bamboo shed with proper ventilation
- Basement with adequate airflow
Step 3: Select a Cultivation Method
For home-based farming, you can choose one of the following methods:
- Bag Method:
- Fill poly bags with substrate (straw or husk) and mushroom spawn.
- Most common for Oyster Mushrooms.
- Tray Method:
- Substrate is spread in shallow trays.
- Ideal for small-scale indoor farming.
- Log Method:
- Suitable for Shiitake mushrooms.
- Logs are inoculated with spawn and placed outdoors.
Recommendation for beginners: Use the bag or tray method for simplicity and faster results.
Step 4: Prepare the Substrate
Mushrooms feed on organic material called substrate. Common substrates in India:
- Paddy straw
- Wheat straw
- Rice husk
- Sugarcane bagasse
Steps to prepare the substrate:
- Chop straw into 2–3 inch pieces.
- Soak in water for 12–24 hours.
- Drain and pasteurize by boiling/steaming for 1–2 hours (kills harmful microbes).
- Let it cool to room temperature before inoculation.
Where to source:
- Local agricultural markets
- Directly from farmers
- Agricultural waste dealers
- Cost: ₹2-5 per kg
Pro Tip: Always keep the substrate clean to avoid contamination.
Step 5: Inoculation (Spawning)
Inoculation is mixing the prepared substrate with mushroom spawn, which acts like seeds:
- Obtain quality spawn from a trusted supplier.
- Mix the spawn evenly with the substrate in clean poly bags or trays.
- Seal the bags and poke small holes for ventilation.
- Purchase certified spawn from authorized dealers.
- Government agricultural universities.
- Established mushroom farms.
- Online agricultural suppliers.
- Cost: ₹40-80 per kg.
Important: Use gloves and maintain hygiene during inoculation.
Step 6: Incubation
- Keep the bags in a dark, warm place (22–28°C for Oyster Mushrooms).
- Maintain 70–80% humidity using a wet cloth or spray bottle.
- The white mycelium will start spreading across the substrate in 15–20 days
Incubation Requirements:
- Temperature: 22-28°C
- Humidity: 70-80%
- Duration: 15-20 days
- No direct light required
- Minimal air circulation
What to expect:
- White mycelium growth appears in 3-5 days
- Bags become fully white in 2-3 weeks
- Ready for fruiting when mycelium covers entire substrate
step 7: Fruiting
Once the substrate is fully colonized with mycelium:
- Move the bags to a well-ventilated area with indirect sunlight.
- Maintain humidity at 85–90% using a misting system or manual spraying.
- Mushrooms will start forming in 5–7 days.
- Harvest when the caps start flattening but before they open completely.
Fruiting Conditions:
- Reduce temperature by 3-5°C
- Increase humidity to 85-90%
- Provide indirect lighting 12 hours daily
- Increase air circulation
Step 8: Harvesting and Post-Harvest Care
- Gently twist and pull mushrooms, or cut with a clean knife.
- A single bag can give 3–4 flushes (harvests).
- Store harvested mushrooms in a cool, ventilated area.
- Mushrooms are highly perishable and should ideally be sold within 24–48 hours.
Harvesting Guidelines:
- First flush appears in 5-7 days after fruiting
- Harvest when caps are fully formed but before spore release
- Cut at base with sharp, clean knife
- Harvest every 2-3 days during peak production
- Expect 3-4 flushes per bag over 2 months

FAQs on Mushroom Farming
Which mushroom variety is best suited for home farming in my local Indian climate?
For most parts of India, Oyster Mushrooms are the best suited for home farming because they grow well in warm and humid conditions (20–30°C), require minimal investment, and are easy for beginners. In cooler regions, Button Mushrooms can also be a good choice.
What are the most common contaminants and how can I prevent them during spawning?
The most common contaminants in mushroom farming during spawning are:
Green mold (Trichoderma) – appears as green patches on substrate.
Black mold (Aspergillus, Rhizopus) – looks like black powdery growth.
Bacteria (sour rot, wet spot) – causes foul smell and slimy patches.
Yeast – shows up as off-white or pinkish spots.
Prevention Tips:
Use only high-quality spawn from trusted suppliers.
Pasteurize/sterilize substrate properly before inoculation.
Maintain clean hands, tools, and environment during spawning (wear gloves, sanitize).
Avoid excess water in the substrate (too much moisture encourages bacteria).
Ensure good ventilation and avoid overcrowding of bags/trays.
How much startup cost and space do I need to run a profitable home mushroom setup?
For a profitable home mushroom farming setup in India, here’s a short and clear FAQ-style answer:
Startup Cost:
A small setup with 100–150 bags requires ₹5,000–₹15,000 (for spawn, substrate, bags, sprayer, thermometer, and shelves).
Medium setup with 300–500 bags may need ₹30,000–₹50,000.
Space Required:
100 bags need around 10 ft × 10 ft (100 sq. ft.) with proper humidity and ventilation.
You can use a spare room, shed, or rooftop room for cultivation.
With proper management, you can earn ₹40,000–₹60,000 per cycle (1.5–2 months) from a small-scale setup.
