Polycarbonate Venlo Greenhouse for Tomato Substrate Culture

Introdution

• Light Performance: PC boards offer excellent light transmittance (80–90%) while diffusing sunlight evenly. This diffused light reduces the risk of leaf scorching, ensuring uniform growth across all crops, which is particularly beneficial for seedlings and leafy greens.

• Insulation & Energy Efficiency: Multi-layer PC panels provide superior thermal insulation compared to glass, minimizing heat loss in cold weather and reducing the need for excessive heating. This lowers energy consumption and operational costs.

• Durability & Safety: PC boards are shatter-resistant, lightweight, and highly resistant to impacts (e.g., hail, wind) and UV radiation, extending the greenhouse’s lifespan. Their lightweight nature also reduces structural stress, making the design easier to expand or modify.

• Cost-Effectiveness: Generally more affordable than glass in both material and installation costs, making it a practical choice for small to medium-scale operations or regions with harsh weather conditions.

• Controlled Growth: Substrates offer balanced drainage and moisture, preventing overwatering or dryness. Nutrient levels are easy to adjust, ensuring steady lettuce growth.

• Reduced Risks: Soil-free setup minimizes soil-borne pests and diseases, cutting pesticide use. This leads to cleaner, safer lettuce.

• Resource Efficiency: Targeted irrigation and fertilization save water (30–40% vs. soil) and nutrients, reducing waste.

• Space Flexibility: Works well in greenhouses or urban farms. Lightweight substrates allow vertical planting, boosting space use.

• Consistent Quality: Uniform substrates result in even size, color, and texture, enhancing market appeal.
