Advantages of protected cultivation in Dehradun
1
ఏడాది పొడవునా పంటలు
Under cover, lettuce can be grown for 10 months a year in Dehradun, so you can supply buyers every week instead of one open-field season.
2
మెరుగైన దిగుబడి మరియు ధర
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
తక్కువ నీరు
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps July's 369 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.

Which polyhouse suits Dehradun?
For polyhouse farming in Dehradun, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in April to June, with moderate humidity of about 41%. In that dry air, wet pads can bring a 37°C May afternoon down to roughly 28°C inside a Fan & Pad polyhouse, cool enough for lettuce and other leafy greens. 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 July (about 369 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, when it is mild and fairly dry.
Crops for Dehradun
Based on Dehradun's climate, the crops with the longest growing windows are lettuce (10 months), capsicum (9 months) and tomato (9 months). Lettuce fits August to May with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Dehradun.

Polyhouse farming in Dehradun: FAQs
Can a polyhouse farm run all year in Dehradun?
Yes, with the right structure. For Dehradun 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 June to July, so plan another crop for those months.
Which polyhouse is best for Dehradun?
With May highs of about 37°C and 35% 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 Dehradun?
Going by the monthly climate, lettuce, capsicum and tomato have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Dehradun?
It can be, if the crop, the structure and the buyers match. In Dehradun, lettuce and capsicum 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 Dehradun?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,190 km away, and we have built 2 projects in Uttarakhand.
