Venlo Glass Greenhouse for Onion Cultivation Stable Structure

The Venlo-type glass greenhouse retains the same modular, gable-roofed Venlo design but uses high-quality glass (often tempered or float glass) as the covering. Its defining characteristics and advantages are:

• Optimal Light Transmittance: Glass provides exceptional clarity with light transmittance up to 95%, maximizing sunlight penetration--critical for high-light-demand crops like tomatoes, peppers, and roses, which thrive on intense, direct light.
• Long-Term Clarity & Maintenance: Glass has a smooth, non-porous surface that resists dirt, algae, and chemical buildup. This ensures consistent light transmission over time, requiring less frequent cleaning compared to PC boards.
• Structural Stability: Glass is rigid and robust, offering strong resistance to environmental stressors. It pairs well with large-scale Venlo designs, supporting extensive commercial operations where durability and longevity are priorities.
• Chemical Resistance: Glass is inert and unaffected by pesticides, fertilizers, or high humidity, making it ideal for environments with frequent chemical applications or high-moisture crops.

The external shading system is controlled by a motor, which can automatically adjust the shading net according to the light intensity, protect the crops from strong sunlight damage, and reduce the temperature in the greenhouse.

The internal shading system is used to adjust the light intensity, while the insulation system maintains the temperature in the greenhouse at night or in cold seasons to reduce heat loss.

The fan wet curtain system reduces the temperature in the greenhouse through the principle of water evaporation and heat absorption, which is suitable for cooling in high temperature seasons.

The heating system includes various heating equipment to ensure that the appropriate growth temperature is maintained in cold seasons or at night.
