Planning polyhouse farming in Kalba? Kalba is in the emirate of Sharjah, United Arab Emirates[1]. This guide works from Kalba's own monthly climate to suggest the protected structure, the crops to start with, and the months each crop is likely to do well.
Climate for polyhouse farming in Kalba
June is the hottest month in Kalba, with average daily highs of about 42°C. January has the coolest nights, averaging 16°C.[2] Rain is scarce: about 117 mm a year. Water for the farm will come from a borewell, well, tanker or municipal supply, so test its salts (EC) and hardness before choosing the system. Kalba sits about 30 m above sea level.[1] On the Köppen–Geiger climate map, Kalba falls in the hot desert zone (BWh).[3]

Advantages of protected cultivation in Kalba
1
Year-round crops
A polyhouse stretches the season: in Kalba cucumber can be grown for about 9 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
With only about 117 mm of rain a year here, drip irrigation under cover saves water: less is lost to evaporation and run-off than in the open field.
4
Less pesticides
Insect net on vents and doors keeps out most pests, so you spray less often.
Which polyhouse suits Kalba?
For polyhouse farming in Kalba, the structure decides which months you can crop and what it costs to run. The heat in Kalba comes with dry air. In May to September, average highs reach 42°C while average humidity is only about 44%. In that dry air, wet pads can bring a 42°C June afternoon down to roughly 33°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. For vine crops such as capsicum and cucumber, a naturally ventilated polyhouse with a shade screen works from December to March and costs less to run.
Sunlight peaks in June at about 7.3 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 November to March, when it is mild and fairly dry.
Crops for Kalba
Based on Kalba's climate, the crops with the longest growing windows are cucumber (9 months), capsicum (7 months) and chilli pepper (7 months). Cucumber fits September to May with Fan & Pad cooling. Strawberry and lilium 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 Kalba.

Kryzen planning estimate from the monthly averages above and each crop's usual day and night temperature range. Variety, soil or substrate temperature and shading change the result, so confirm with a trial.
Every project starts with your site data: plot size, water quality and the crops your buyers want. We review it with you online and prepare a project report before construction starts.
Towns near Kalba
We also plan and build farms in these towns near Kalba:
Yes, with the right structure. For Kalba we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to October, so plan another crop for those months.
Which polyhouse is best for Kalba?
With June highs of about 42°C and 40% average humidity in that month, we would start with a Fan & Pad polyhouse for leafy greens.
Which crops should I grow in a polyhouse in Kalba?
Going by the monthly climate, cucumber, capsicum and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
