Hydroponics is a method of growing plants without soil, which has become increasingly popular in recent years as a way to cultivate crops in a controlled environment. One of the most important aspects of hydroponic farming is the proper oxygenation of the water. Water oxygenation involves the movement and aeration of water to ensure that the roots of the plants are adequately supplied with oxygen. In this article, we will discuss the importance of water oxygenation in hydroponic systems, how it is done, and the consequences of low oxygenation of water for plants.
