Planning polyhouse farming in Natham? Natham is a small town in Dindigul district, Tamil Nadu, home to about 24,000 people (GeoNames)[1][2], about 310 km from Bengaluru. We have used the monthly climate for Natham to plan a structure, a growing system and a crop calendar, so you can compare them with your own plot and buyers.
Climate for polyhouse farming in Natham
April is the hottest month in Natham, with average daily highs of about 37°C. January has the coolest nights, averaging 18°C.[3] The area gets about 962 mm of rain a year, most of it in May and September to November, peaking in October at about 197 mm. Average humidity stays at 75% or more in October to December, which raises the risk of leaf disease and slows evaporative cooling. Natham sits about 245 m above sea level.[2] On the Köppen–Geiger climate map, Natham falls in the tropical savanna (dry winter) zone (Aw).[4]

Advantages of protected cultivation in Natham
1
Year-round crops
Under cover, capsicum can be grown for the whole year in Natham, 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 197 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 (October 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.[5]
Which polyhouse suits Natham?
For polyhouse farming in Natham, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in February to September, with moderate humidity of about 64%. In that dry air, wet pads can bring a 37°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.
Sunlight peaks in April at about 6.5 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 and June to August, when it is mild and fairly dry.
Crops for Natham
Based on Natham'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 Natham.

310 kmto Bengaluru, the nearest metro (straight line)
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.[6] Local demand in Natham may be small for exotic greens, so plan where the rest of the harvest goes. Dindigul, about 30 km away, is the nearest larger market on our list.

Polyhouse farming in Natham: FAQs
Can a polyhouse farm run all year in Natham?
Yes, with the right structure. For Natham 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 June and September, so plan another crop for those months.
Which polyhouse is best for Natham?
With April highs of about 37°C and 59% 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 Natham?
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 Natham?
It can be, if the crop, the structure and the buyers match. In Natham, 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 Natham?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 980 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.
