What is a nethouse?
Shade on top, insect net on the sides
Quick answer
A nethouse, also called a shade net house, is a galvanised steel structure covered with shade net and insect net instead of plastic film. It reduces sunlight and heat, keeps most insects out and protects plants from wind and hail. It costs much less than a polyhouse and is simple to run, but gives less protection from heavy rain and cold.
Because the net lets rain and air through, a nethouse stays cooler than a naturally ventilated polyhouse but protects less from rain. It suits cucumber, capsicum, tomato, leafy greens and nurseries in warm regions.
What a nethouse is made of
01Shade net roof
UV-stabilised shade net on top blocks part of the sunlight, so leaves stay cooler and do not scorch.
02Insect net sides
40-mesh insect net closes the sides, keeping most flying pests out while air moves through.
03GI steel frame
Galvanised steel pipes and wires hold the nets tight and take the load of wind and hail.

Types of nethouse
Two designs. We recommend one after seeing your land, wind and rainfall.
Flat-roof nethouse
A flat net roof on a grid of GI pipes and tensioned wires.
Best forLarge, low-cost vegetable farms on level land
Dome nethouse
A curved roof like a tunnel, which sheds rain and wind better.
Best forWindy and rainy areas, and a longer life
Roof and purlin options
Cable purlin
Tensioned GI cables hold the roof net between the columns.
Best forLower cost; suits sites with low wind
Pipe purlin
GI pipes in place of cables hold the roof net in shape under load.
Best forExposed, windy plots and a longer life
Single layer
One shade net on the roof.
Best forMost vegetable and nursery farms
Double layer
A second net under the roof: 50% white shade net or 50% aluminet.
Best forVery hot regions and heat-sensitive crops
Shade net
Pick the right shade factor
The shade factor is how much sunlight the net blocks. A 50% net blocks half the light. Kryzen chooses it for your crop and climate.

Shade net types
Tape × tape shade net
Woven from flat HDPE tapes. Economical and widely used for vegetables, flowers and nurseries.
Mono × mono shade net
Woven from round monofilament threads. Stronger and holds its shape longer on large nethouses.
Aluminet (add-on)
Aluminium-coated shade net that reflects heat. It keeps the crop cooler in summer and holds some warmth on winter nights.
Which shade net fits your farm?
| Product | Material | Shade / weight | UV life | Best for |
|---|---|---|---|---|
| Tape × tape | Virgin HDPE | 35–75% shade | 3 years | Vegetables, flowers, nurseries |
| Mono × mono | Monofilament HDPE | 100–125 GSM | 3 years | Nethouses, greenhouses (BIS approved) |
| Aluminet | Aluminium-coated | 50% or 80% shade | 4 years | Floriculture, horticulture |
Colour options
Green
Blends with the farm and gives soft, even shade. Popular for nurseries and vegetables.
White
Reflects more heat and spreads light evenly, so the crop stays cooler under the net.
Black
The most widely used colour. Gives the full rated shade and lasts well in strong sun.
All our shade nets are UV-stabilised. We suggest a colour for your crop and climate.
Compare shade nets
Monofilament vs tape shade net
Both are UV-stabilised HDPE and give the same shade. The difference is how the net is made, and that decides how strong it is and how long it stays tight.
Tape netFlat tapes
Monofilament netRound threads
| Point | Tape net | Monofilament net |
|---|---|---|
| Thread | Flat HDPE tapes, woven or knitted | Round monofilament HDPE threads |
| Strength | Good | Stronger |
| Stretch | Can stretch and sag over time | Does not stretch, so it stays tight on the frame |
| Wind and weather | More affected by strong wind | Holds up better to wind, sun and weather |
| Weight | Lightweight | 100–125 GSM |
| Cost | Economical | Costs more |
| UV life | 3 years | 3 years |
| Best for | Vegetables, flowers and nurseries on a budget | Large nethouses and windy sites (BIS approved) |
Choose tape net for a lower budget. Choose monofilament for large or windy sites where the net must stay tight for years. Our team recommends one after the site inspection.
Upgrade for hot regions
Summer above 40 °C? Upgrade to aluminium reflective net
Where summer temperatures cross 40 °C, a normal shade net is not enough. Aluminet reflects the extra heat away from your crop, so plants keep growing through the hottest months.
Reflects heat
The metallised surface reflects sunlight and heat instead of absorbing it, so less heat reaches the crop.
About 5 °C cooler
Retractable aluminet lowers the temperature under the net by about 5 °C.
Warmer winter nights
It also holds back some of the warmth that would escape on cold nights.
| Aluminet | Details |
|---|---|
| Material | High-quality metallised knitted screen with a special anti-oxidation and UV-resistant coating |
| UV stabilised | Yes |
| UV life | 4 years* |
| Shade | 50% or 80% |
| Width | 4.2 m, 4.5 m or 5.5 m |

Per acre, averaged over a year of two crops. It depends on variety, season, market price and how well the crop is managed.
Subsidy has an area limit
- NHM / MIDH: the government pays 50% of ₹710 per m² (₹355 per m²), but only on up to 2,500 m² per farmer. That is about 0.6 acre, so the most you can get is about ₹8.88 lakh, even if your nethouse is bigger.
- 4,000 m² is the polyhouse limit, not the nethouse limit.
- NHB: projects bigger than 2,500 m² can apply for a credit-linked subsidy of 50% of the eligible project cost, up to ₹100 lakh per project. A bank loan is part of the project.

Illustration only, not a guarantee. Based on the project price for the size you pick plus 18% GST, an NHM/MIDH subsidy of ₹8.88 lakh (50% of ₹710/m² on up to 2,500 m²) received after year 1, subject to approval, revenue for the crop plan you pick per acre per month, scaled from the low end of its range at 50% capacity use to the high end at 95%, running cost of about ₹45,500 per acre a month in year 1 rising by the opex increase you select each year, crop rates rising by the crop rate increase you select each year, and a net change of ₹3 lakh per acre every 4 years. Year 1 counts 9 months of sales. Crop plan revenue is a tentative Kryzen estimate. Tax free: agricultural income is generally exempt from income tax in India under Section 10(1); check your case with a tax adviser.
What you earn depends on your crop
A two-crop plan, such as cucumber in summer and capsicum or tomato in winter, keeps the nethouse working most of the year. Your project report uses current prices from Price Watcher, and Buyers Connect helps you sell after harvest.

Nethouse vs regular farming
How a nethouse compares with open-field farming
An open field costs nothing to cover, but sun, pests, wind and hail decide your harvest. A nethouse protects your crop for a small extra cost.
| Point | Nethouse | Open field |
|---|---|---|
| Sun scorch and heat | Reduced by shade net | Common in summer |
| Pests | Lower: insect net | High, with more spraying |
| Wind and hail | Net takes the impact | Crop damaged |
| Heavy rain | Partly protected | Crop exposed |
| Yield and quality | Higher and more uniform | Varies season to season |
| Upfront cost | Lowest of all protected structures | Low |
Nethouse vs polyhouse
Nethouse or naturally ventilated polyhouse?
Both grow profitable crops. The right one depends on your crop, climate and budget.
| Point | Nethouse | Polyhouse (NVPH) |
|---|---|---|
| Covering | Shade net roof and insect net sides | UV film roof, roll-up curtains and insect net |
| Rain and cold | Partly protected | Protected |
| Temperature | Cooler; air moves through the net | Warmer; vents and curtains control it |
| Electricity | Least | Low: mainly irrigation |
| Build cost | Lowest | Medium |
| Best for | Cucumber, green capsicum, tomato, leafy greens, nursery | Coloured capsicum, cucumber, tomato, flowers |
Nethouse vs fan and pad
Nethouse or fan and pad polyhouse?
A fan and pad polyhouse controls temperature with exhaust fans and wet cooling pads. It costs more to build and run, but suits high-value crops in hot, dry regions.
| Point | Nethouse | Fan and pad polyhouse |
|---|---|---|
| Covering | Shade net roof and insect net sides | Closed film house with exhaust fans and wet cooling pads |
| Temperature control | Shade only; air moves through the net | Active cooling with fans and pads |
| Rain and cold | Partly protected | Fully protected |
| Electricity | Least | Highest: fans and pumps |
| Build cost | Lowest | Highest |
| Best for | Cucumber, green capsicum, tomato, leafy greens, nursery | Roses, gerbera, orchids, exotics, hot dry regions |

What is a nethouse?
A nethouse, also called a shade net house, is a galvanised steel structure covered with shade net on top and insect net on the sides instead of plastic film. It cuts harsh sun, keeps most insects out and protects crops from wind and hail.
What is the difference between a nethouse and a polyhouse?
A nethouse is covered with shade net and insect net. A polyhouse is covered with plastic film. A polyhouse protects from rain and cold. A nethouse costs less and stays cooler.
Which shade net is best for a nethouse?
It depends on your crop. A 35% net suits tomato, capsicum, cucumber and leafy greens. A 50% net suits nurseries and spices. A 75% net suits flowers such as rose, gerbera and carnation. 80–90% nets are too dark for most crops. Kryzen chooses the shade factor for your crop and climate.
What is the difference between tape and monofilament shade net?
Tape net is woven from flat HDPE tapes and costs less. Monofilament net is woven from round threads, so it is stronger and keeps its shape longer. Both are UV-stabilised.
How long does a nethouse last?
The GI steel frame lasts many years. Shade net and insect net are usually replaced every 3 to 5 years, depending on sun, dust and monsoon load. Kryzen gives a 3-year warranty on both nets, and keeping the nets tight makes them last longer.
What is the difference between cable purlin and pipe purlin?
Both hold the roof net between the columns. Cable purlin uses tensioned GI cables and costs less, so it suits low-wind sites. Pipe purlin uses GI pipes, keeps its shape under load and suits windy, exposed plots.
Can I get a subsidy for a nethouse?
Yes. Under NHM/MIDH, a tubular nethouse gets 50% of the ₹710/m² cost norm on up to 2,500 m² per farmer, so about ₹8.88 lakh at most. Projects above 2,500 m² can apply to NHB for a 50% credit-linked subsidy. Our team prepares the project report and subsidy file.
Is a nethouse good for cucumber?
Yes. Cucumber is a fast summer crop in a nethouse. Many farmers follow it with capsicum or tomato in winter.
Can I grow soil-less inside a nethouse?
Yes. You can install cocopeat grow bags, NFT channels, Dutch buckets or troughs inside a nethouse.
