Planning polyhouse farming in Sihor? Sihor is a town in Bhavnagar district, Gujarat, home to about 55,000 people (GeoNames)[1][2], about 160 km from Ahmedabad.

Climate for polyhouse farming in Sihor
May is the hottest month in Sihor, with average daily highs of about 41°C. January has the coolest nights, averaging 13°C.[3] The area gets about 865 mm of rain a year, most of it in June to September, peaking in July at about 281 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 Sihor
1
Year-round crops
Under cover, chilli pepper can be grown for the whole year in Sihor, 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 281 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.[5]
Which polyhouse suits Sihor?
For polyhouse farming in Sihor, the structure decides which months you can crop and what it costs to run. The heat in Sihor comes with dry air. In April to May, average highs reach 41°C while average humidity is only about 41%. In that dry air, wet pads can bring a 41°C May afternoon down to roughly 33°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 to January and August and costs less to run.
Plan for heavy rain in July (about 281 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May at about 7.3 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 October to February, when it is mild and fairly dry.
Crops for Sihor
Based on Sihor's climate, the crops with the longest growing windows are chilli pepper (all year), cucumber (11 months) and brinjal (11 months). Chilli pepper fits all year with Fan & Pad cooling. Strawberry is hard to time here, so we would leave it out of the first season. These are the crops we would plan first for polyhouse farming in Sihor.

₹7,198Spending per person per month, urban Gujarat, 2023–24[6]
160 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.[6] Local demand in Sihor may be small for exotic greens, so plan where the rest of the harvest goes. Bhavnagar, about 20 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Ahmedabad is within a day's delivery, about 160 km away.

Polyhouse farming in Sihor: FAQs
Can a polyhouse farm run all year in Sihor?
Yes, with the right structure. For Sihor we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to July, so plan another crop for those months.
Which polyhouse is best for Sihor?
With May highs of about 41°C and 45% 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 Sihor?
Going by the monthly climate, chilli pepper, cucumber and brinjal have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Sihor?
It can be, if the crop, the structure and the buyers match. In Sihor, chilli pepper and cucumber 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 Sihor?
Yes. Our nearest site is our Nashik warehouse, about 270 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.
