This greenhouse features roof vents for natural ventilation, with optional manual or motorized rollers to control opening and closing. Ideal for temperate and subtropical regions with average annual temperatures of 20-40℃ and abundant sunlight, particularly suitable for tropical areas with high temperatures and rainfall.

• Double-round-tube Column: Two φ42mm hot-dip galvanized round tubes connected by hoop clamps. Compared to traditional square-tube columns, this design reduces costs by 20% while increasing anti-deformation capacity by 15% under wind pressure tests.
• Lightweight Design: 18% reduction in overall weight improves transportation and installation efficiency by 30%.
• Intelligent Ventilation System: Top electric window and side wall film rolling device work in tandem for precise temperature control (±2℃), saving 35% more energy than conventional greenhouses.

Ideal for leafy vegetables (spinach, lettuce), solanaceous fruits (tomatoes, peppers), berry fruits (strawberries, blueberries), and ornamental flowers (roses, hydrangeas). Perfect for crops requiring precise temperature and humidity regulation.

• Smart fertilizer mixing with precise concentration control
• Customizable drip/hydroponic systems saving 50% water
• Fog spray system reduces temperature 3-5℃ and improves seedling survival by 20-30%

• High-capacity exhaust fans reduce temperature 3-5℃
• Circulation fans eliminate temperature/humidity variations
• Retractable shade nets (30-90% shading rate)

• Galvanized vertical racks for 3x space utilization
• High-strength climbing support for vine crops
• Weed-resistant ground cover fabric

• Real-time environmental monitoring (temperature, humidity, light, CO₂, soil EC)
• IoT controllers for remote operation via mobile app
