1. What is Polyhouse Farming?
A polyhouse (or polytunnel/greenhouse) is a climate-controlled structure covered with UV-stabilized polyethylene film. It allows you to grow crops year-round by controlling temperature, humidity, light, and ventilation — regardless of outside weather conditions.
In India, polyhouse farming has exploded in the last 5 years, driven by government subsidies (up to 90% of construction cost), growing demand for off-season vegetables, and the shift toward precision agriculture. The India greenhouse horticulture market is projected to reach USD 3.08 Billion by 2033 at 9.84% CAGR.
Key Advantage
Polyhouse farming yields 5-10x more produce per square meter compared to open-field farming, while using 30-50% less water. Off-season crops fetch 2-3x market price.
2. Types of Polyhouses in India
| Type | Cost/sq m | Climate Control | Best For |
|---|---|---|---|
| Low-cost Tunnel | Rs.300-500 | Basic (ventilation only) | Nurseries, seasonal extension |
| Naturally Ventilated (NV) | Rs.800-1200 | Side/top vents, insect mesh | Vegetables, flowers (most common in India) |
| Fan & Pad (Climate Controlled) | Rs.1500-2500 | Active cooling, heating, humidity | High-value flowers, exotic veggies, tissue culture |
| Hi-tech (Fully Automated) | Rs.3000-5000 | IoT sensors, automated everything | Export-quality produce, research farms |
For most Indian farmers, a Naturally Ventilated (NV) polyhouse offers the best balance of cost, effectiveness, and subsidy eligibility. It's the most popular choice and covers 70%+ of polyhouse installations in India.
3. Construction Cost Breakdown
Here's a detailed cost breakdown for a standard 4,000 sq meter (1 acre) Naturally Ventilated polyhouse — the most common commercial size:
| Component | Cost (Rs.) | % of Total |
|---|---|---|
| GI Steel Structure (tubular frame) | Rs.18,00,000 | 45% |
| UV-stabilized Poly Film (200 micron) | Rs.4,00,000 | 10% |
| Foundation & Civil Work | Rs.3,50,000 | 9% |
| Drip Irrigation System | Rs.3,00,000 | 7.5% |
| Fogger/Misting System | Rs.2,00,000 | 5% |
| Insect Mesh & Shade Net | Rs.2,50,000 | 6% |
| Growing Media & Beds | Rs.2,00,000 | 5% |
| Electrical & Automation | Rs.1,50,000 | 3.75% |
| Transportation & Installation | Rs.2,00,000 | 5% |
| Miscellaneous & Contingency | Rs.1,50,000 | 3.75% |
| TOTAL (4,000 sq m / 1 acre) | Rs.40,00,000 | 100% |
| Cost per sq meter | Rs.1,000/sq m | |
4. Government Subsidy — How to Get 50-90%
The Indian government heavily subsidizes polyhouse farming through multiple schemes. Here are the main ones:
NHM (National Horticulture Mission)
- Subsidy: 50% of cost (up to Rs.56 Lakhs/hectare for NV polyhouse)
- Additional 15-25% subsidy for SC/ST/women/small farmers
- Covers: Structure, irrigation, shade net, mulching
- Apply through: State Horticulture Department
MIDH (Mission for Integrated Development of Horticulture)
- Subsidy: 50-65% of total project cost
- For: Hi-tech greenhouses, tissue culture labs, cold storage
- Credit-linked subsidy through NABARD
State-specific Schemes (UP, Maharashtra, Karnataka)
- UP: Up to 90% subsidy for small/marginal farmers under Mukhyamantri Kisan Ayushman Yojana
- Maharashtra: Rs.25-30 Lakh/acre additional via PKVY
- Karnataka: Raitha Siri scheme covers 75% for SC/ST farmers
Real Example: 4,000 sq m Polyhouse in UP
- Total cost: Rs.40,00,000
- NHM subsidy (50%): -Rs.20,00,000
- Additional SC/ST benefit (15%): -Rs.6,00,000
- Farmer's investment: Rs.14,00,000 (65% subsidy)
- With bank loan at 7%: EMI of Rs.16,700/month for 10 years
How to Apply for Subsidy (Step by Step)
- 1 Register on the NHM/MIDH portal of your state's horticulture department website. You'll need Aadhaar, land documents, and bank details.
- 2 Submit a project report with technical specifications, cost estimates, and crop plan. This is where a professional company like Wishfy helps — we prepare the entire project report.
- 3 Get technical approval from the District Horticulture Officer (DHO). They inspect your land and verify the project report.
- 4 Secure bank loan (if needed). NABARD, SBI Agriculture, and other banks offer specific agri-infrastructure loans at 7-9% interest.
- 5 Construction — Build through an empaneled vendor. The structure must meet NHM technical standards (GI pipe thickness, poly film micron, etc.).
- 6 Post-construction inspection by DHO. They verify specs match the approved project report.
- 7 Subsidy released to your bank account (typically within 30-90 days of inspection).
5. Best Crops for Polyhouse Farming
High-Profit Vegetables
- Capsicum (Color) — Rs.80-150/kg, 3 crops/year
- Cherry Tomato — Rs.100-200/kg, export demand
- Cucumber (English) — Rs.40-80/kg, continuous harvest
- Lettuce & Exotic Greens — Rs.200-400/kg for hotels
- Strawberry — Rs.200-500/kg, seasonal premium
High-Profit Flowers
- Gerbera — Rs.5-15/stem, 200-250 stems/sq m/year
- Rose (Dutch) — Rs.8-25/stem, year-round demand
- Carnation — Rs.5-12/stem, long shelf life
- Orchid — Rs.50-200/stem, export quality
- Anthurium — Rs.30-80/piece, hotel/corporate demand

7. Step-by-Step: How to Start
- 1 Site Assessment: Check water availability, electricity, road access, and soil. Minimum 0.5 acre of flat land recommended.
- 2 Choose Crop: Based on local market demand, climate zone, and buyer network. Start with what sells locally.
- 3 Get Project Report: A detailed technical + financial report needed for subsidy application and bank loan.
- 4 Apply for Subsidy: Through state horticulture portal. Processing time: 30-90 days.
- 5 Construction: 45-60 days for a 4,000 sq m polyhouse with an experienced team.
- 6 Crop Training: Learn polyhouse crop management — pruning, trellising, fertigation, pest control. We provide hands-on training.
- 7 First Harvest: Typically 60-90 days after transplanting (vegetables). Flowers may take 4-6 months for first commercial harvest.
8. Common Mistakes to Avoid
- 1 Building without market research — Know your buyer before you grow. Visit mandis, connect with aggregators, talk to hotels and exporters.
- 2 Cheap structure — Using thin GI pipes or low-micron poly film saves money upfront but fails in 2-3 years. Invest in quality from day one.
- 3 Ignoring water quality — High EC or pH water damages drip systems and plants. Get water tested before building.
- 4 No backup power — Ventilation failure in summer = crop loss within hours. Always have a generator or inverter backup.
- 5 Starting too big — Begin with 1,000-2,000 sq m if you're new. Learn the crop management skills before scaling to 4,000+ sq m.
