RESEARCH:
Hydroponics is a subset of hydroculture and is a way of growing plants using mineral nutrient solutions, using just water. Researchers discovered in the 18th century that plants absorb mineral nutrients as inorganic ions in water. Normally soil is thought to be required for plant growth, but in actuality, soil is not needed at all. When the mineral nutrients in the soil dissolve in water, plant roots have the ability to absorb them. When the required mineral nutrients are introduced into a plant's water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics. Hydroponics is also a standard technique in biology research and teaching. Advantages

There are quite a few reasons why hydroponics are becoming more popular around the world. •No soil is needed for hydroponics
The water stays in the system and can be reused, therefore, which is pleasing to frugal people, because there are lower water costs •It is possible to control the nutrition levels in their entirety - therefore, lower nutrition costs •No nutrient pollution at all is released into our atmosphere •Pests and diseases are easier to get rid of than in soil because of the container's mobility •Plants are easier to harvest

More fresh fruit and vegetables due to no pesticide being used. Today, hydroponics is an established branch of cultivation. Progress has been fast, and results found in different countries have proved it to make more sense and to have very big advantages over average methods of normal farming.
