Planning polyhouse farming in Pasighat? Pasighat is a small town in East Siang district, Arunachal Pradesh, home to about 26,000 people (GeoNames)[1][2], about 930 km from Kolkata. 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 Pasighat
August is the hottest month in Pasighat, with average daily highs of about 34°C. January has the coolest nights, averaging 11°C.[3] The area gets about 2,656 mm of rain a year, most of it in April to October, peaking in July at about 568 mm. Average humidity stays at 75% or more in July to September, which raises the risk of leaf disease and slows evaporative cooling. Pasighat sits about 153 m above sea level.[2] On the Köppen–Geiger climate map, Pasighat falls in the humid subtropical with dry winters zone (Cwa).[4]

Advantages of protected cultivation in Pasighat
1
Year-round crops
A polyhouse stretches the season: in Pasighat 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 568 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 Arunachal Pradesh can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[6]
Which polyhouse suits Pasighat?
For polyhouse farming in Pasighat, the structure decides which months you can crop and what it costs to run. In Pasighat the heat comes with humidity: during May to August average humidity is about 73%. Wet pads cool much less in humid air: on a typical August afternoon they would only bring 34°C down to about 32°C. So we usually start with a tall naturally ventilated polyhouse with wide roof vents, insect net and a shade screen. A Fan & Pad polyhouse still makes sense if buyers need lettuce through the hottest months, but expect a smaller temperature drop than in dry inland towns.
Plan for heavy rain in July (about 568 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. A nethouse, the lowest-cost option, can grow hardy crops in February to March and November to December, when it is mild and fairly dry.
Crops for Pasighat
Based on Pasighat's climate, the crops with the longest growing windows are cucumber (7 months), chilli pepper (7 months) and tomato (6 months). Cucumber fits March to May, July and September to November in a naturally ventilated polyhouse. Lilium and broccoli 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 Pasighat.

Urban households in Arunachal Pradesh spent an average of ₹9,877 per person per month in 2023–24, above the all-India urban average of ₹7,078.[7] Local demand in Pasighat may be small for exotic greens, so plan where the rest of the harvest goes.

Polyhouse farming in Pasighat: FAQs
Can a polyhouse farm run all year in Pasighat?
Yes, with the right structure. For Pasighat we would plan a tall naturally ventilated polyhouse with wide vents and insect net. Even then, lettuce is hard to grow in June to September, so plan another crop for those months.
Which polyhouse is best for Pasighat?
With August highs of about 34°C and 76% average humidity in that month, we would start with a tall naturally ventilated polyhouse with wide vents and insect net.
Which crops should I grow in a polyhouse in Pasighat?
Going by the monthly climate, capsicum, chilli pepper and tomato have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Pasighat?
It can be, if the crop, the structure and the buyers match. In Pasighat, 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 Pasighat?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 2,220 km away, and we have built one project in Arunachal Pradesh.
Is there a subsidy for polyhouse or hydroponic farms in Arunachal Pradesh?
Yes. Protected cultivation projects in Arunachal 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.
