The Venlo-type PC board greenhouse is a modular, gable-roofed structure characterized by its use of polycarbonate (PC) panels as the primary covering material. Its key features and advantages include:
Roof window opening systems are automated mechanisms for greenhouse ventilation. These systems control the opening and closing of roof-mounted windows via motors or pneumatic devices, triggered by sensors monitoring temperature, humidity, or CO₂ levels.
They facilitate air circulation, expel excess heat or moisture, and draw in fresh air--critical for regulating the greenhouse microclimate and supporting plant respiration.
Constant-temperature heating equipment maintains stable, optimal temperatures in greenhouses, especially in cold conditions. It includes boilers, radiant heaters, or heat pumps, paired with thermostats to adjust output.
By keeping temperatures within a target range (e.g., 18-25°C for tomatoes), it prevents frost damage, ensures consistent growth rates, and supports year-round cultivation regardless of external weather.
