Hydroponic is a type of horticulture that involves growing plants without soil by using mineral nutrient solutions in an aqueous solvent. Terrestrial plants may grow with their roots exposed to the nutritious liquid or in addition the roots may be physically supported by an inert medium such as perlite, or cocopeat. Hydroponics offers many advantages, notably a decrease in water usage in agriculture. Hydroponics takes much less water to grow to produce, it could be possible in the future for people in harsh environments with little accessible water to grow their own food.
