Planning polyhouse farming in Saiha? Saiha is a small town in Saiha district, Mizoram, home to about 25,000 people (GeoNames)[1][2], about 470 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 Saiha
April is the hottest month in Saiha, with average daily highs of about 31°C. January has the coolest nights, averaging 8°C.[3] The area gets about 1,504 mm of rain a year, most of it in May to October, peaking in July at about 372 mm. Average humidity stays at 75% or more in June to November, which raises the risk of leaf disease and slows evaporative cooling. Saiha sits about 729 m above sea level.[2] On the Köppen–Geiger climate map, Saiha falls in the humid subtropical with dry winters zone (Cwa).[4]

Advantages of protected cultivation in Saiha
1
Year-round crops
Under cover, tomato can be grown for 10 months a year in Saiha, 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 July's 372 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 November), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Mizoram can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Saiha?
For polyhouse farming in Saiha, the structure decides which months you can crop and what it costs to run. With average highs between 23°C and 31°C through the year, Saiha suits a naturally ventilated polyhouse for most crops. Fan & Pad cooling is rarely needed; spend the budget on good ventilation, insect net and a shade screen. Plan for heavy rain in July (about 372 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 March to April and November, when it is mild and fairly dry.
Crops for Saiha
Based on Saiha's climate, the crops with the longest growing windows are tomato (10 months), capsicum (9 months) and chilli pepper (9 months). Tomato fits February 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 Saiha.

Urban households in Mizoram spent an average of ₹8,709 per person per month in 2023–24, above the all-India urban average of ₹7,078.[6] Local demand in Saiha may be small for exotic greens, so plan where the rest of the harvest goes.
