Protected cultivation — growing crops inside polyhouses, greenhouses, or shade nets — is rapidly gaining popularity among Indian farmers looking to improve yield quality, extend growing seasons, and reduce dependence on unpredictable weather. If you're considering your first polyhouse, here's a beginner-friendly overview of what to expect.
What is polyhouse farming? A polyhouse is a structure covered with UV-stabilised polythene sheeting that creates a controlled microclimate for your crops. Inside, you can manage temperature, humidity, and light more precisely than in open fields, which typically results in higher yields and better quality produce — especially for vegetables, flowers, and high-value crops.
Which crops work best? Tomatoes, capsicum, cucumbers, and leafy greens are among the most common polyhouse crops in India, along with cut flowers like roses and gerberas. The right crop choice depends on your local climate, market demand, and the size of polyhouse you plan to build.
What does it cost to get started? Setup costs vary widely based on the structure type (naturally ventilated vs. fan-and-pad cooled), size, and the irrigation and fertigation systems you pair with it. Many state governments in India also offer subsidies of 50% or more on polyhouse construction, which can significantly lower your upfront investment.
What else do you need? A polyhouse works best alongside a proper drip irrigation and fertigation setup, since precise water and nutrient control is one of the biggest advantages of protected cultivation. Good ventilation, pest screening, and regular structural maintenance are also essential for long-term success.
