Hydroponic cultivation or water cultivation is one of the new technologies in the production of agricultural products, which is done without the need for a soil substrate, and the nutrients needed by the plant are provided through a nutrient solution. In the hydroponic system, the quality of the consumed water is of particular importance and has a direct effect on the root structure and absorption of nutrients. Also, the roots of plants need oxygen for their normal functioning, and therefore, increasing the percentage of oxygen saturation in water enables plants to absorb more oxygen through the roots, especially at night when they need more oxygen.
