WebHydroponics is the growth of plants in a mixture of water and mineral nutrients, without the use of any type of soil. Almost any plant can be grown in a hydroponic system, with natural light and/or artificial light, and there are no worries about outside temperature, climate, growing seasons, etc. [1] B ackground.
