Deep Water Culture (DWC) is a popular hydroponic technique used for cultivating leafy greens in a nutrient-rich, oxygenated water solution. In DWC systems, plant roots are suspended directly in a water reservoir, allowing constant access to nutrients and oxygen, which promotes rapid growth and robust yields. This method is highly efficient for leafy greens like lettuce, spinach, and herbs, as it supports their need for consistent hydration and nutrient uptake. With proper management of dissolved oxygen (DO) levels and pH, DWC offers a sustainable, soil-free approach to producing fresh, high-quality greens year-round.
The amount of oxygen in water or nutrient solutions used for irrigating leafy greens. It affects root health, nutrient absorption, and overall plant growth, helping to prevent root diseases and plant stress.
Oxidation-Reduction Potential (ORP) plays a crucial role in maintaining water quality and pathogen control in Deep Water Culture (DWC) systems for leafy green production. ORP measures the water’s ability to break down contaminants and control microbial activity, which is vital for plant health. In DWC setups, maintaining optimal ORP levels can prevent harmful bacteria, algae, and pathogens from thriving in the nutrient-rich solution. This control reduces the risk of root diseases and supports a cleaner, healthier growing environment, enabling leafy greens to absorb nutrients efficiently and grow faster. By carefully managing ORP, growers can improve both the quality and yield of their leafy greens in DWC systems.
