The Venlo-type PC board greenhouse is a modular, gable-roofed structure characterized by its use of polycarbonate (PC) panels as the primary covering material. Its key features and advantages include:

• 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.

• Healthier roots: Substrates (e.g., coir, perlite) ensure good drainage and air flow, preventing rot and supporting strong root development.
• Precise nutrition: Easy to control nutrient supply, tailored to zinnias' growth stages for vibrant blooms and sturdy stems.
• Less pest/disease risk: Soil-free setup reduces soil-borne issues (fungi, nematodes), lowering the need for chemicals.
• Efficient resource use: Substrates retain moisture well, saving water, while targeted feeding cuts nutrient waste--cost and eco-friendly.
• Flexible growing: Suits small spaces, containers, or indoor setups. Light substrates make moving plants easy, adapting to diverse needs.
