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.

• Superior root health: Substrates (e.g., peat, perlite) offer ideal drainage and aeration, preventing root rot and fostering strong root systems.
• Targeted nutrition: Easy to adjust nutrient levels, ensuring petunias get precise feeds for vibrant blooms and lush growth.
• Fewer pests/diseases: Avoids soil-borne issues (like fungi), reducing reliance on pesticides for cleaner cultivation.
• Resource efficiency: Saves water (substrates retain moisture well) and cuts nutrient waste, aiding cost and eco-friendliness.
• Flexible growing: Works in small spaces, indoors, or containers. Light substrates simplify movement, suiting diverse setups.
