For decades, a “net house” in India meant a small shade structure over a few guntas of vegetables. That picture is out of date. At 10 acres and above, a net house becomes something very different — a structured, year-round agribusiness that supplies organised buyers at contracted prices, not a subsistence plot.
This guide explains commercial net house farming end to end: what the structure actually is, how it compares to open-field and polyhouse farming, the land and water you need, what a project is made of, the returns you can realistically expect, the risks to check before you invest, and how a partner like Agrifirst guides you through every step of it.
What is a commercial net house?
A net house (shade-net house) is a galvanised-iron (GI) framed structure covered with agricultural shade netting that creates a protected micro-climate for crops. The net cuts excess heat and sunlight, keeps insects and birds out, and shields the crop from wind, dust and hail — while still allowing natural ventilation.
“Commercial” simply means doing this at scale — 10 acres or more — with drip fertigation, planned crop rotations, trained labour and a route to organised markets. At that size the economics change completely: fixed costs get spread thin, buyers take you seriously, and the farm produces enough consistent volume to be run like a business.
Because it uses netting rather than a fully sealed, climate-controlled envelope, a net house delivers most of the benefits of protected cultivation at a fraction of a polyhouse’s cost — which is exactly why it has become the entry point for serious commercial farming in India.
Net house vs open-field farming
Open-field farming leaves the crop exposed to everything — pests, heat spikes, unseasonal rain, hail and price-crashing gluts. A net house changes the risk profile.
| Open field | Commercial net house | |
|---|---|---|
| Pest & insect pressure | High | Sharply reduced (physical barrier) |
| Heat / light stress | Full exposure | Moderated micro-climate |
| Yield per acre | Baseline | Typically much higher |
| Produce quality & grade | Variable | Consistent, retail/export grade |
| Water use | High | Lower (drip fertigation) |
| Weather & hail risk | High | Largely protected |
| Price realisation | Mandi-dependent | Premium, contracted buyers |
The result is higher yields, cleaner produce, fewer sprays, and — crucially — the ability to grow the high-value crops that organised buyers actually pay a premium for.
Net house vs polyhouse: which should you choose?
Both are protected-cultivation structures, and Agrifirst builds both. The difference is the level of control — and the cost.
| Net house (shade net) | Polyhouse (NVPH) | |
|---|---|---|
| Climate control | Partial (shade, ventilation) | High (naturally ventilated, covered) |
| Capital cost / acre | Lower | Higher |
| Payback | Faster | Longer |
| Best crops | Cucumber, tomato, capsicum, chillies | Coloured capsicum, exotics, cut flowers |
| Subsidy | Often run as a non-subsidy model | Typically NHB/NHM subsidy-linked |
| Complexity | Simpler to operate | More technical |
A simple way to decide: if you want a lower-cost, faster-payback entry into commercial protected farming with proven vegetable crops, the net house is usually the right first move. If you’re targeting the very highest-value crops (coloured capsicum, cut flowers) and can invest more, look at commercial polyhouse farming.
Why commercial scale (10+ acres) matters
Protected farming only becomes a real business at scale. Below a few acres you get a better vegetable plot; at 10 acres and above you get an enterprise. Three reasons:
- Buyers need volume. Supermarket chains, food companies and exporters buy on contract — they need reliable, graded volume week after week, which only a commercial-scale farm can supply.
- Fixed costs spread out. Agronomy, supervision, packhouse handling and logistics cost roughly the same whether you farm 2 acres or 10 — so per-acre overheads fall as you scale.
- A second crop fills the year. At commercial scale you can run a planned double-crop rotation — for example cucumber through summer, then tomato or capsicum through winter — so the structure earns income across all twelve months instead of one season.
Land, climate and water requirements
Before anything is built, the site has to qualify. A good commercial net house site needs:
- Contiguous land — ideally 10+ acres in one block, reasonably level, with road access for inbound material and outbound produce.
- A reliable water source — borewell, well or canal with enough year-round yield, and water quality (EC/pH) suitable for drip fertigation.
- A workable agro-climate — the local temperature and humidity band should suit the planned crops; the net house widens that band but doesn’t replace it.
- Power and labour — dependable power for pumps and fertigation, and access to trainable local labour.
A proper project always starts with a site and water assessment — skip it and you inherit avoidable problems later.
What a commercial net house project is made of
A turnkey 10-acre project is far more than “poles and net.” The major components are:
- GI structural framework — galvanised columns, cabling and foundations engineered for wind load.
- Shade netting — agricultural-grade net at the right shade percentage for the crop.
- Drip & fertigation system — precise water and nutrient delivery to every plant.
- Weed-mat, beds and trellising — for clean, disease-free, high-density cropping.
- Civil works — foundations, apron and pathways.
- Accessories — mulch, clips, twine, trays and crop-support hardware.
Build quality here directly determines the structure’s lifespan and how well it protects the crop — it is not the place to cut corners.
The benefits of protected cultivation
Put together, a commercial net house delivers:
- Higher yields per acre than open field.
- Better, more uniform quality that meets retail and export grades.
- Fewer pesticides thanks to physical pest exclusion.
- Water savings through drip fertigation.
- Weather protection from heat, wind, dust and hail.
- Year-round, plannable production that buyers can contract against.
The two things that make or break the business
A net house is only the hardware. Two things decide whether it becomes a profitable business:
- Agronomy. Crop planning, nursery, nutrition, irrigation scheduling and integrated pest management (IPM) have to be done right, cycle after cycle. Good agronomy is the difference between an average yield and a premium one.
- Market linkage. Growing quality produce means little if you sell it into a crashing mandi. The value is captured only when the harvest goes to organised buyers — supermarkets, food processors and exporters — at contracted, premium prices.
An investor who owns the land but doesn’t have deep agronomy and buyer relationships needs a partner who does. That is the core of a hand-held commercial model.
The economics: what returns to expect
Numbers vary with crop, market and management, so treat these as indicative, not guaranteed. For a well-run 10-acre commercial net house on Agrifirst’s double-crop model:
- Project cost: roughly ₹2.5 crore (about ₹25 lakh per acre).
- Annual revenue: in the region of ₹1.7 crore.
- Annual net profit: around ₹1 crore.
- ROI: roughly 40%+ per year, with payback in about 2–2.5 years.
- Tax: income from agriculture is exempt under Section 10(1) of the Income Tax Act.

Risks and due diligence before you invest
Every real business has risk. The ones that matter here — and how to check them:
- Execution / agronomy risk. Ask who actually runs the crop, and whether they’ve done it at commercial scale before.
- Market risk. Confirm there is a real buyer network and, ideally, contracted off-take — not just a promise to “help you sell.”
- Water risk. Insist on a water yield and quality test before committing.
- Build-quality risk. Check the structural spec, materials and warranty — a cheap structure fails early.
- Partner credibility. Look for a track record, references and a genuinely end-to-end scope rather than a one-time construction contract.
Doing this diligence up front is what separates a sound investment from an expensive lesson.
