Naturally Ventilated Polyhouse

A Naturally Ventilated Polyhouse (NVPH) is a protected cultivation structure that relies on natural airflow to regulate the internal environment, creating optimal conditions for plant growth without artificial ventilation systems. It operates on ventilation principles like the stack effect, where warm air rises and exits through roof vents, and cross ventilation, where side vents allow cool air to enter. It is widely used in vegetable cultivation and floriculture for efficient, sustainable, and cost-effective farming.

FAQ

How does ventilation work in an NVPH?

Ventilation is achieved through roof vents and side vents. The stack effect allows warm air to rise and exit through the roof vents, while cooler air enters through the side vents, ensuring continuous airflow.

What crops can be grown in an NVPH?

NVPH is suitable for a variety of crops, including vegetables, flowers, herbs, and exotic plants that require a controlled and sustainable environment for optimal growth.

What are the benefits of using an NVPH?

NVPHs reduce energy costs, improve microclimate control, protect crops from harsh weather, and minimize pest infestations, making them efficient and sustainable for horticulture and floriculture.

What factors affect the performance of an NVPH?

The performance depends on the polyhouse orientation, vent design, local climate, and the use of insect-proof screens, all of which influence airflow, temperature regulation, and crop health.
