Planning polyhouse farming in Sandi? Sandi is a small town in Uttar Pradesh, home to about 25,000 people (GeoNames)[1][2], about 310 km from Delhi. This guide works from Sandi's own monthly climate to suggest the protected structure, the crops to start with, and the months each crop is likely to do well.
Climate for polyhouse farming in Sandi
May is the hottest month in Sandi, with average daily highs of about 43°C. January has the coolest nights, averaging 7°C.[3] The area gets about 906 mm of rain a year, most of it in June to September, peaking in July at about 290 mm. Average humidity stays at 75% or more in August to September, which raises the risk of leaf disease and slows evaporative cooling. On the Köppen–Geiger climate map, Sandi falls in the humid subtropical with dry winters zone (Cwa).[4]

Advantages of protected cultivation in Sandi
1
Year-round crops
A polyhouse stretches the season: in Sandi cucumber can be grown for about 7 months a year under cover, longer than in the open field.
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 290 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 (August to September), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Uttar Pradesh can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Sandi?
For polyhouse farming in Sandi, the structure decides which months you can crop and what it costs to run. The heat in Sandi comes with dry air. In April to June, average highs reach 43°C while average humidity is only about 29%. In that dry air, wet pads can bring a 43°C May afternoon down to roughly 31°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 November and costs less to run.
Plan for heavy rain in July (about 290 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May at about 6.7 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 February to March and October to November, when it is mild and fairly dry.
Crops for Sandi
Based on Sandi's climate, the crops with the longest growing windows are cucumber (7 months), chilli pepper (7 months) and lettuce (7 months). Cucumber fits March to May and July to October with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Sandi.

₹5,474Spending per person per month, urban Uttar Pradesh, 2023–24[6]
310 kmto Delhi, the nearest metro (straight line)
Urban households in Uttar Pradesh spent an average of ₹5,474 per person per month in 2023–24, below the all-India urban average of ₹7,078.[6] Local demand in Sandi may be small for exotic greens, so plan where the rest of the harvest goes. Farrukhabad, about 40 km away, is the nearest larger market on our list.

Polyhouse farming in Sandi: FAQs
Can a polyhouse farm run all year in Sandi?
Yes, with the right structure. For Sandi we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to September, so plan another crop for those months.
Which polyhouse is best for Sandi?
With May highs of about 43°C and 24% 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 Sandi?
Going by the monthly climate, cucumber, chilli pepper and lettuce have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Sandi?
It can be, if the crop, the structure and the buyers match. In Sandi, 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 Sandi?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 950 km away, and we have built 6 projects in Uttar Pradesh.
Is there a subsidy for polyhouse or hydroponic farms in Uttar Pradesh?
Yes. Protected cultivation projects in Uttar Pradesh 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.
