Hydroponics is a method of growing plants in artificial environments without soil. Plants receive nutrition from a nutrient solution surrounding the roots. Hydroponics allows you to regulate the conditions for growing plants - to create a nutritional regime for the root system that fully meets the plant's needs for nutrients, the concentration of carbon dioxide in the air that is most favorable for photosynthesis, and also to regulate the temperature of the air and root zone, air humidity, intensity and duration of lighting. Creating optimal conditions for the growth and development of plants ensures very high yields, better quality and in a shorter time. Growing plants this way is less labor-intensive than in soil culture, water and nutrients are spent more economically. The supply of nutrient solution is easily automated. In hydroponics, weed control is practically eliminated
