Planning polyhouse farming in Wadhwan? Wadhwan is a town in Surendranagar district, Gujarat[1], about 100 km from Ahmedabad. 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 Wadhwan
May is the hottest month in Wadhwan, with average daily highs of about 44°C. January has the coolest nights, averaging 11°C.[2] The area gets about 751 mm of rain a year, most of it in June to September, peaking in July at about 243 mm. Average humidity stays at 75% or more in July to September, which raises the risk of leaf disease and slows evaporative cooling.

Advantages of protected cultivation in Wadhwan
1
Year-round crops
Under cover, chilli pepper can be grown for 11 months a year in Wadhwan, 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 July's 243 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 (July to September), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Gujarat can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Wadhwan?
For polyhouse farming in Wadhwan, the structure decides which months you can crop and what it costs to run. The heat in Wadhwan comes with dry air. In April to June, average highs reach 44°C while average humidity is only about 42%. In that dry air, wet pads can bring a 44°C May afternoon down to roughly 34°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. For vine crops such as capsicum and cucumber, a naturally ventilated polyhouse with a shade screen works from December and costs less to run.
Plan for heavy rain in July (about 243 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May at about 7.4 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, when it is mild and fairly dry.
Crops for Wadhwan
Based on Wadhwan's climate, the crops with the longest growing windows are chilli pepper (11 months), tomato (10 months) and cucumber (10 months). Chilli pepper fits February to December with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Wadhwan.

₹7,198Spending per person per month, urban Gujarat, 2023–24[5]
100 kmto Ahmedabad, the nearest metro (straight line)
Urban households in Gujarat spent an average of ₹7,198 per person per month in 2023–24, close to the all-India urban average of ₹7,078.[5] Local demand in Wadhwan may be small for exotic greens, so plan where the rest of the harvest goes. Surendranagar Dudhrej Wadhwan, about 5 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Ahmedabad is within a day's delivery, about 100 km away.

Polyhouse farming in Wadhwan: FAQs
Can a polyhouse farm run all year in Wadhwan?
Yes, with the right structure. For Wadhwan we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to September, so plan another crop for those months.
Which polyhouse is best for Wadhwan?
With May highs of about 44°C and 39% average humidity in that month, we would start with a Fan & Pad polyhouse for leafy greens.
Which crops should I grow in a polyhouse in Wadhwan?
Going by the monthly climate, chilli pepper, tomato and cucumber have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Wadhwan?
It can be, if the crop, the structure and the buyers match. In Wadhwan, chilli pepper and tomato 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 Wadhwan?
Yes. Our nearest site is our Nashik warehouse, about 370 km away, and we have built 12 projects in Gujarat.
Is there a subsidy for polyhouse or hydroponic farms in Gujarat?
Yes. Protected cultivation projects in Gujarat 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.
