Advanced Airflow Engineering for Precision Growing
Double Vent Greenhouses feature two independently controlled roof ventilation systems, maximizing airflow flexibility and precision climate control. The greenhouse polyethylene cover is connected with reusable PVC or aluminum locking profiles.
This dual-vent design provides exceptional heat release during summer while maintaining targeted growing zones during cooler seasons.
It is designed for standard wind loads and vertical loads. Side walls can be covered with polyethylene, polycarbonate, or with a curtain (manual or automated).
The strategic placement of opposing vents creates ideal circulation patterns that prevent humidity buildup and promote uniform plant development.
A double vent greenhouse is an optimal solution for specific climate conditions and crop requirements.
