Venlo Glass Greenhouse for Flower Growing with Substrate Culture

Introdution
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.

Support systems
Substrates offer stable physical structure (porosity, water - retention). Nutrient and pH levels are adjustable, ensuring flowers get optimal nutrition. For example, orchids thrive in well - drained, nutrient - balanced substrates, avoiding soil - related pH swings.
No soil means fewer soil - borne pathogens (e.g., root rot fungi) and pests (like nematodes). This cuts pesticide use, making flowers healthier and “greener” for markets.
Substrates enable precise irrigation and fertilization. Drip systems deliver water/nutrients directly to roots, saving 30–50% water vs. soil. Nutrients recycle better, lowering waste and costs.
