Venlo Glass Greenhouse for Lettuce Hydroponics 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.

• Rapid Growth & High Yields: Precise nutrient delivery accelerates growth, shortening harvest cycles by 10-15 days. Vertical setups maximize space, yielding 2-3x more than soil cultivation.
• Water & Resource Efficiency: Recirculating systems save ~90% water vs. soil. No need for soil preparation or excessive fertilizers, cutting resource waste.
• Reduced Risks: Soil-free environment minimizes soil-borne pests/diseases, lowering pesticide use. Produces cleaner, safer lettuce with fewer contaminants.
• Consistent Quality: Controlled conditions (nutrients, light, pH) ensure uniform size, color, and texture, enhancing market appeal.
• Flexible Cultivation: Works in greenhouses, urban farms, or indoor spaces, enabling year-round production regardless of climate.
