Naturally Ventilated Polyhouse
A naturally ventilated polyhouse is a type of greenhouse structure that relies on natural airflow to regulate the internal environment, rather than using mechanical ventilation systems. It is designed to create an optimal growing environment for various crops by utilizing natural ventilation methods such as side and roof vents. This type of polyhouse helps maintain appropriate temperature, humidity, and carbon dioxide levels, which are crucial for healthy plant growth.
Key Engineering Features:
Natural Convective Airflow: Roof ridge and side vents dissipate excess heat without electrical power
UV-Stabilized Cladding: Diffused light transmission protecting crops from sunburn and leaf scorching
Corrosion-Resistant GI Frame: Heavy-duty galvanized tubular pipes ensuring 15+ years structural durability
Insect & Pest Protection: Fully enclosed with 40/50 mesh insect nets preventing sucking pest ingress
Integrated Micro-Irrigation: Compatible with automated drip fertigation and micro-fogging humidity controls
