A Polyhouse is a type of protected farming structure made using UV-stabilized polyethylene sheets that creates a controlled environment for growing crops.
It helps farmers grow high-value vegetables, fruits, flowers, and plants by controlling temperature, humidity, light, and irrigation.
Polyhouse farming allows year-round cultivation, higher yield, and better quality produce compared to open-field farming.
Controlled temperature & humidity
Protection from rain, wind, pests, and extreme weather
Efficient use of water and fertilizers
Suitable for high-value crops
Can be naturally ventilated or climate-controlled
Ideal for commercial farming
Vegetables: Capsicum, Tomato, Cucumber, Lettuce
Flowers: Rose, Gerbera, Carnation, Orchid
Fruits: Strawberry
Nursery plants & saplings
Higher crop yield (2–4 times more)
Better quality & uniform produce
Reduced pest and disease attack
Less water usage (drip irrigation)
Off-season cultivation possible
Higher income for farmers
| Merits | Demerits |
|---|---|
| Higher productivity | High initial investment |
| Year-round cultivation | Requires technical knowledge |
