The DWC system is a soilless cultivation method that efficiently grows plants by providing roots with a nutrient-rich solution environment of optimal depth, stable nutrient supply, and sufficient oxygen. This system eliminates common soil cultivation issues like uneven fertility and soil-borne diseases while allowing precise control of nutrient composition and environmental conditions.

• Planting Bench: Rectangular structure made of hot-dip galvanized pipes with waterproof film, 15-20cm depth for optimal root immersion.
• Nutrient Solution Circulation: Includes reservoir (scalable capacity), water pump (selected for system size), and corrosion-resistant PVC piping.
• Planting Board & Cups: Foam board with customizable holes holds plastic planting cups (5-8cm diameter for leafy greens).
• Oxygenation System: Air compressor and microporous aeration pipe maintain dissolved oxygen levels.
• Water Chiller: Maintains optimal root zone temperature (18-22°C for lettuce) to prevent hypoxia.

The water pump circulates nutrient solution from reservoir to planting bench, providing continuous nutrition. Roots absorb nutrients while immersed, with oxygen supplied via aeration. The system automatically returns excess solution for pH/EC adjustment and temperature control.

• Stable Nutrient Supply: Deep solution (10-20cm) acts as "nutrient warehouse" with buffering capacity against temperature/pH fluctuations.
• Optimal Root Environment: Oxygen gradient ensures aerobic respiration; spacious area allows unrestricted root growth.
• Easy Maintenance: Transparent components enable visual monitoring; simple cleaning/disinfection between cycles.
• Versatile Cultivation: Ideal for leafy greens (lettuce, spinach) and supports fruiting plants (tomatoes, peppers) in early stages.
