In hydroponic systems, which method is used to prevent root rot?

In hydroponic systems, preventing root rot is crucial for maintaining healthy plant growth. Providing sufficient oxygen to the roots is effective because root rot is typically caused by over-saturation and lack of oxygen, leading to anaerobic conditions that favor the growth of pathogens. Hydrated roots need not only nutrients and water, but also adequate oxygen to thrive and prevent diseases like root rot.

By ensuring that the roots receive enough oxygen, either through aeration methods like air stones or by utilizing systems like nutrient film technique (NFT) or deep water culture (DWC) that allow the roots to access oxygen, the risk of developing root rot is significantly reduced. This focus on oxygen availability creates a healthier environment for roots, enabling them to absorb nutrients efficiently and reducing the chances of fungal and bacterial infections.
