Planning polyhouse farming in Gadwal? Gadwal is a town in Jogulamba Gadwal district, Telangana, home to about 63,000 people (Census 2011)[1], about 150 km from Hyderabad. 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 Gadwal
April is the hottest month in Gadwal, with average daily highs of about 40°C. December has the coolest nights, averaging 16°C.[2] The area gets about 680 mm of rain a year. The wettest months are July to September, peaking in September at about 151 mm. Average humidity stays at 75% or more in September to October, which raises the risk of leaf disease and slows evaporative cooling. Gadwal sits about 324 m above sea level.[1] On the Köppen–Geiger climate map, Gadwal falls in the hot semi-arid zone (BSh).[3]

Advantages of protected cultivation in Gadwal
1
Year-round crops
Under cover, cucumber can be grown for the whole year in Gadwal, 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
With only about 680 mm of rain a year here, drip irrigation under cover saves water: less is lost to evaporation and run-off than in the open field.
4
Less pesticides
Insect net on vents and doors keeps out most pests, and controlled ventilation helps with leaf disease in the humid months (September to October), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Telangana can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Gadwal?
For polyhouse farming in Gadwal, the structure decides which months you can crop and what it costs to run. The heat in Gadwal comes with dry air. In March to May, average highs reach 40°C while average humidity is only about 38%. In that dry air, wet pads can bring a 40°C April afternoon down to roughly 30°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 September to December and costs less to run.
Sunlight peaks in April at about 6.8 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 January and June, when it is mild and fairly dry.
Crops for Gadwal
Based on Gadwal's climate, the crops with the longest growing windows are cucumber (all year), chilli pepper (all year) and brinjal (all year). Cucumber fits all year with Fan & Pad cooling. Lilium and strawberry 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 Gadwal.

150 kmto Hyderabad, the nearest metro (straight line)
The Census counted 54,000 people in Gadwal in 2001 and 63,000 in 2011, a rise of 18%. In 1991 it was 41,000.[1] Urban households in Telangana spent an average of ₹9,131 per person per month in 2023–24, above the all-India urban average of ₹7,078.[5] Local demand in Gadwal may be small for exotic greens, so plan where the rest of the harvest goes. Raichur, about 50 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Hyderabad is within a day's delivery, about 150 km away.

Polyhouse farming in Gadwal: FAQs
Can a polyhouse farm run all year in Gadwal?
Yes, with the right structure. For Gadwal we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to May, so plan another crop for those months.
Which polyhouse is best for Gadwal?
With April highs of about 40°C and 36% 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 Gadwal?
Going by the monthly climate, cucumber, chilli pepper and brinjal have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Gadwal?
It can be, if the crop, the structure and the buyers match. In Gadwal, 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 Gadwal?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 460 km away, and we have built 14 projects in Telangana.
Is there a subsidy for polyhouse or hydroponic farms in Telangana?
Yes. Protected cultivation projects in Telangana 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.
