Natural Ventilated Polyhouse

Natural Ventilated Polyhouse (NVPH) is a widely used agriculture greenhouse structure that regulates the internal growing climate purely through natural air movement — side and top/ridge ventilation — without depending on electrically powered fans or pads. It is one of the most practical and cost-effective polyhouse designs for round-the-year protected cultivation.

Key Features

• Ridge/top ventilation combined with side ventilation for continuous natural air exchange

• No electricity or fan dependency for cooling and air circulation

• Strong GI pipe/truss framework built to standard specifications

• UV-stabilized polyethylene film covering

• Insect-proof netting fitted on all ventilation openings

• Drip irrigation and fertigation compatible

• Roll-up or fixed side curtains for climate adjustment

• Available in customized spans and gutter heights according to land and crop requirements

Benefits of Natural Ventilated Polyhouse

• Creates a stable natural microclimate without running/operational costs

• Low power consumption compared to fan-and-pad systems

• Can be built to standard specifications commonly required for horticulture subsidy schemes

• Helps improve crop quality and uniformity

• Reduces pest and insect entry through insect-proof netting

• Efficient use of water through drip irrigation and fertigation

• Durable, low-maintenance structure suitable for long-term use

• Suitable for small, medium and commercial farming projects

Suitable Crops

Natural Ventilated Polyhouse is commonly suitable for:

• Tomato

• Capsicum

• Cucumber

• Exotic Vegetables

• Cut Flowers (Rose, Gerbera, Carnation)

• Nursery Plants and seedling raising

Crop suitability depends on the local climate, cultivation method and market requirements.

Natural Ventilated Polyhouse Structure

A typical Natural Ventilated Polyhouse consists of:

Natural Ventilated Polyhouse Design

The design and dimensions of a Natural Ventilated Polyhouse should be selected according to:

• Available land area

• Crop type and height

• Local wind and climate conditions

• Required ventilation percentage

• Irrigation requirements

• Covering material

• Farming budget

A properly engineered, site-specific design helps ensure optimal ventilation, structural strength and long-term performance.

Natural Ventilated Polyhouse Cost

The cost of a Natural Ventilated Polyhouse depends on its span and gutter height, structural material, covering film, ventilation percentage, irrigation, fertigation, crop-support system, installation and site conditions.

For an accurate price, the project should be evaluated according to the required area and specifications.
