Sainpoly Agriculture greenhouse frame Venlo type Polycarbonate Glass greenhouse for seeds vegetables hybrid tomato

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.

Shading System: Internal and external shading systems are often used to block sunlight in the summer, effectively lowering indoor temperatures and preventing UV radiation. They also protect crops from overexposure to sunlight and high temperatures.

Ventilation System: Automatically turns ventilation equipment on and off based on set thresholds, creating a suitable growing environment for crops and ensuring a stable greenhouse environment.

Cooling System: Cooling measures are necessary to ensure the normal growth and development of crops in a greenhouse. Water curtain fan cooling systems are currently the most widely used cooling method.

Heating System: Heating measures are necessary to ensure the normal growth and development of crops in a greenhouse. Hot air furnaces, hot water radiators, and electric heaters are commonly used heating methods in greenhouses.

Fertigation System: It offers advantages such as water conservation, energy conservation, increased yield, higher quality, and increased efficiency. Common irrigation systems used in greenhouses include drip irrigation, sprinkler irrigation, micro-sprinkler irrigation, and infiltration irrigation.

Seedling system: One of the most basic components of modern greenhouse. It consists of a support frame, a bed surface, a bed frame, and a seedling tray. The main functions of the seedbed system are to support crops, regulate moisture, maintain air circulation, and facilitate management.
