Planning polyhouse farming in Bengaluru? Bengaluru is a city of about 96.2 lakh people (Census 2011) in Bengaluru Urban district, Karnataka[1]. Below we use the town's monthly temperatures, humidity and rainfall to work out which structure fits, which crops to grow and in which months, before you spend on construction.
Climate for polyhouse farming in Bengaluru
April is the hottest month in Bengaluru, with average daily highs of about 35°C. January has the coolest nights, averaging 14°C.[2] The area gets about 844 mm of rain a year, most of it in May and July to October, peaking in September at about 152 mm. Average humidity stays at 75% or more in June to November, which raises the risk of leaf disease and slows evaporative cooling. Bengaluru sits about 920 m above sea level, so nights run cooler than in the plains around it.[1] On the Köppen–Geiger climate map, Bengaluru falls in the tropical savanna (dry winter) zone (Aw).[3]

Advantages of protected cultivation in Bengaluru
1
Year-round crops
Under cover, cucumber can be grown for 10 months a year in Bengaluru, so you can supply buyers every week instead of one open-field season.
2
Better yield and price
Plants grow without rain, hail and wind damage, so yields are higher and more even, and clean, graded produce sells at a better price, especially off-season.
3
Less water
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps September's 152 mm of rain off the crop and the soil.
4
Less pesticides
Insect net on vents and doors keeps out most pests, and controlled ventilation helps with leaf disease in the humid months (June to November), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Karnataka can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Bengaluru?
For polyhouse farming in Bengaluru, the structure decides which months you can crop and what it costs to run. With average highs between 26°C and 35°C through the year, Bengaluru suits a naturally ventilated polyhouse for most crops. Fan & Pad cooling is rarely needed; spend the budget on good ventilation, insect net and a shade screen. Sunlight peaks in March at about 6.6 kWh per m² a day, so add a shade screen for leafy greens in the brightest months.
A nethouse, the lowest-cost option, can grow hardy crops in November to February and June, when it is mild and fairly dry.
Crops for Bengaluru
Based on Bengaluru's climate, the crops with the longest growing windows are cucumber (10 months), chilli pepper (10 months) and brinjal (10 months). Cucumber fits May to February in a naturally ventilated polyhouse. Lilium and carnation are hard to time here, so we would leave them out of the first season. These are the crops we would plan first for polyhouse farming in Bengaluru.

₹8,169Spending per person per month, urban Karnataka, 2023–24[5]
The Census counted 65.4 lakh people in Bengaluru in 2001 and 96.2 lakh in 2011, a rise of 47%.[1] Urban households in Karnataka spent an average of ₹8,169 per person per month in 2023–24, above the all-India urban average of ₹7,078.[5] A city of this size has hotels, restaurants, modern retail and quick-commerce stores within its own limits, so most harvests can be sold locally. Line up two or three buyers before planting and agree on grade and delivery days.

Polyhouse farming in Bengaluru: FAQs
Can a polyhouse farm run all year in Bengaluru?
Yes, with the right structure. For Bengaluru we would plan a naturally ventilated polyhouse.
Which polyhouse is best for Bengaluru?
With April highs of about 35°C and 49% average humidity in that month, we would start with a naturally ventilated polyhouse.
Which crops should I grow in a polyhouse in Bengaluru?
Going by the monthly climate, capsicum, tomato and cucumber have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Bengaluru?
It can be, if the crop, the structure and the buyers match. In Bengaluru, cucumber and chilli pepper have the longest seasons under cover. Confirm prices and volumes with buyers first; our Detailed Project Report works out the cost, yield and returns for your plot.
Does Kryzen build polyhouses in Bengaluru?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 680 km away, and we have built 38 projects in Karnataka.
Is there a subsidy for polyhouse or hydroponic farms in Karnataka?
Yes. Protected cultivation projects in Karnataka can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department. Check the current rate and area limit when you apply.
