The DWC system is a soilless cultivation system that enables plants to grow efficiently by providing roots with optimal nutrient solution depth, stable nutrient supply, and sufficient oxygen. This system overcomes traditional soil cultivation challenges 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 growth.

Includes reservoir (capacity from tens to thousands of liters depending on scale) and water pump sized according to system requirements.

Corrosion-resistant PVC pipes for nutrient solution delivery and return between reservoir and planting bench.

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

Air compressor and microporous aeration pipe maintain optimal dissolved oxygen levels for root respiration.

Maintains ideal root zone temperature (18-22°C for lettuce), preventing high-temperature stress and nutrient absorption issues.

The water pump circulates nutrient solution from reservoir to planting bench where roots absorb nutrients while immersed. The air pump maintains oxygen levels through aeration. The system continuously monitors and adjusts solution properties (pH, EC, temperature) as plants consume nutrients.
