The DWC system is a soilless cultivation method that provides plant roots with optimal nutrient solution depth, stable nutrient supply, and sufficient oxygen. This system eliminates common soil cultivation problems like uneven fertility and soil-borne diseases while allowing precise control of nutrient composition and environmental conditions.

Rectangular structure made of hot-dip galvanized pipes with waterproof film lining. Depth of 15-20cm ensures sufficient nutrient solution immersion for root development.

Includes reservoir (scalable from tens to thousands of liters), water pump (selected based on system size), and corrosion-resistant PVC piping for efficient nutrient delivery and return.

Foam board with customizable holes holds planting cups (5-8cm diameter for leafy vegetables) that allow nutrient solution access to roots while supporting plant stems.

Air compressor and microporous aeration pipe maintain optimal dissolved oxygen levels (18-22°C) for root respiration and nutrient absorption.

Maintains ideal root zone temperature, especially crucial in summer to prevent high-temperature stress and oxygen depletion.

The water pump circulates nutrient solution from reservoir to planting bench, while the air pump maintains oxygen levels. The system continuously monitors and adjusts pH, EC, and temperature as plants consume nutrients.

• Stable Nutrient Supply: Deep solution (10-20cm) acts as "nutrient warehouse" with excellent buffering capacity against temperature/pH fluctuations
• Superior Root Environment: Oxygen gradient ensures aerobic respiration; spacious area allows unrestricted root growth
• Easy Maintenance: Transparent components enable visual monitoring; simple cleaning without substrate residues
• Versatile Applications: Ideal for leafy greens (lettuce, spinach) and supports fruiting crops (tomatoes, peppers)
