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.

• Root health: Substrates (e.g., coir, perlite) ensure good drainage and air-flow. Roots grow stronger, avoiding rot and absorbing nutrients better.
• Precise nutrition: Easy to tailor nutrient mixes for watermelon growth stages. Boosts fruit quality (sweeter, uniform size) and cuts waste.
• Fewer pests/diseases: No soil means less risk of soil-borne issues (nematodes, fungi). Reduces pesticide use for cleaner, sustainable growth.
• Water efficiency: Substrates balance moisture well. Drip systems save water, and irrigation schedules are easier to optimize.
• Flexible growing: Works in greenhouses, containers, etc. Enables off-season or year-round cultivation, expanding market.
