Planning polyhouse farming in Periyakulam? Periyakulam is a town in Theni district, Tamil Nadu, home to about 43,000 people (GeoNames)[1][2], about 320 km from Bengaluru. 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 Periyakulam
April is the hottest month in Periyakulam, with average daily highs of about 36°C. January has the coolest nights, averaging 17°C.[3] The area gets about 1,123 mm of rain a year, most of it in May to November, peaking in October at about 219 mm. Average humidity stays at 75% or more in June to December, which raises the risk of leaf disease and slows evaporative cooling. Periyakulam sits about 356 m above sea level.[2] On the Köppen–Geiger climate map, Periyakulam falls in the tropical savanna (dry winter) zone (Aw).[4]

Area averages (a grid cell of about 50 km) for 2001–2025, from NASA POWER, centred on Periyakulam, adjusted for the town's elevation[5]. Rainfall and night temperatures at your plot can differ, especially near hills and the coast.[3]
Advantages of protected cultivation in Periyakulam
1
Year-round crops
Under cover, capsicum can be grown for the whole year in Periyakulam, 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 October's 219 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 December), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Tamil Nadu can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[6]
Which polyhouse suits Periyakulam?
For polyhouse farming in Periyakulam, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in March to May, with moderate humidity of about 63%. In that dry air, wet pads can bring a 36°C April afternoon down to roughly 32°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. Capsicum, cucumber and tomato do well in a naturally ventilated polyhouse with a shade screen. If you want one structure, decide by crop: greens all year point to Fan & Pad; vine crops point to a naturally ventilated house.
Plan for heavy rain in October (about 219 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in March at about 6.4 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 December to February, when it is mild and fairly dry.
Crops for Periyakulam
Based on Periyakulam's climate, the crops with the longest growing windows are capsicum (all year), tomato (all year) and cucumber (all year). Capsicum fits all year with Fan & Pad cooling. 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 Periyakulam.

Urban households in Tamil Nadu spent an average of ₹8,325 per person per month in 2023–24, above the all-India urban average of ₹7,078.[7] Local demand in Periyakulam may be small for exotic greens, so plan where the rest of the harvest goes.

Polyhouse farming in Periyakulam: FAQs
Can a polyhouse farm run all year in Periyakulam?
Yes, with the right structure. For Periyakulam we would plan Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops. Even then, lettuce is hard to grow in March to May, so plan another crop for those months.
Which polyhouse is best for Periyakulam?
With April highs of about 36°C and 61% average humidity in that month, we would start with Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops.
Which crops should I grow in a polyhouse in Periyakulam?
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 Periyakulam?
It can be, if the crop, the structure and the buyers match. In Periyakulam, capsicum 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 Periyakulam?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 960 km away, and we have built 9 projects in Tamil Nadu.
Is there a subsidy for polyhouse or hydroponic farms in Tamil Nadu?
Yes. Protected cultivation projects in Tamil Nadu 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.
