Planning polyhouse farming in Tehri? Tehri is a large city in Uttarakhand, home to about 6.2 lakh people (Census 2011)[1], about 230 km from Delhi. We have used the monthly climate for Tehri 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 Tehri
June is the hottest month in Tehri, with average daily highs of about 36°C. January has the coolest nights, averaging 6°C.[2] The area gets about 1,297 mm of rain a year, most of it in June to September, peaking in July at about 368 mm. Average humidity stays at 75% or more in July to September, which raises the risk of leaf disease and slows evaporative cooling. On the Köppen–Geiger climate map, Tehri falls in the humid subtropical with dry winters zone (Cwa).[3]

Advantages of protected cultivation in Tehri
1
Year-round crops
A polyhouse stretches the season: in Tehri chilli pepper can be grown for about 6 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 368 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 Uttarakhand can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Tehri?
For polyhouse farming in Tehri, the structure decides which months you can crop and what it costs to run. With average highs between 20°C and 36°C through the year, Tehri 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 368 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.
Sunlight peaks in May at about 6.9 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 March to April and October to November, when it is mild and fairly dry.
Crops for Tehri
Based on Tehri's climate, the crops with the longest growing windows are chilli pepper (6 months), lettuce (6 months) and cucumber (5 months). Chilli pepper fits April and July to November in a naturally ventilated polyhouse. Orchids and anthurium 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 Tehri.

230 kmto Delhi, the nearest metro (straight line)
The Census counted 6.1 lakh people in Tehri in 2001 and 6.2 lakh in 2011, about the same.[1] Urban households in Uttarakhand spent an average of ₹7,547 per person per month in 2023–24, above the all-India urban average of ₹7,078.[6] Tehri is large enough for steady local sales to restaurants, hotels and fruit-and-vegetable retailers. Start with a farm size that matches the orders you can confirm. Dehradun, about 40 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Delhi is within a day's delivery, about 230 km away.

Polyhouse farming in Tehri: FAQs
Can a polyhouse farm run all year in Tehri?
Yes, with the right structure. For Tehri we would plan a naturally ventilated polyhouse. Even then, lettuce is hard to grow in June to August, so plan another crop for those months.
Which polyhouse is best for Tehri?
With June highs of about 36°C and 58% average humidity in that month, we would start with a naturally ventilated polyhouse.
Which crops should I grow in a polyhouse in Tehri?
Going by the monthly climate, tomato, lettuce and capsicum have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Tehri?
It can be, if the crop, the structure and the buyers match. In Tehri, chilli pepper and lettuce 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 Tehri?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,210 km away, and we have built 2 projects in Uttarakhand.
Is there a subsidy for polyhouse or hydroponic farms in Uttarakhand?
Yes. Protected cultivation projects in Uttarakhand 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.
