Growing plants in aquatic medium is called hydroponics
hydroponics
Hydroponics substitute a nutrient medium in place of soil. for the plants to root and grow. The nutrient medium may be either a water solution or an inert material.
With hydroponics plants are grown in an inert medium such as gravel. All the plants nutrients are supplied in a nutrient solution that flows along the container the plants are growing in. So no soil is required.
The medium is a sterile substrate that takes the place of soil; it provides a place for the plants to grow in as well as a medium through which the nutrient solution can pass. Hydroponics employs a sterile medium, one that does not interact with the plants - perlite, vermiculite, inert stone or rock wool. Hydroponic gardening system that is based on water, not soil. So container is a hydroponic growing medium. There are various types of hydroponic growing mediums like Oasis Cube, Coconut Fiber, Fillers, Ebb and Flow System and aeroponics.

Hydroponics is the growing of plants in a solution without the use of soil. Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Plants are grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool, or coconut husk.
Hydroponics is not a method for classifying plants, rather it's a method for growing plants. Although you could absolutely use a hydroponic system outdoors (I have seen it done), most people tend to use the hydroponic method indoors. Just to clarify, Hydroponics is the method for growing plants without conventional soil. Most hydroponics systems involve the use of a "medium" which acts as a substitute for soil, and the roots hang in nutrient enriched water. The fundamental difference between hydroponics and soil is this: Non-hydroponic systems generally use the soil as the source for roots to obtain nutrients (ie nitrogen phosphorous, etc) while Hydroponic systems use water as the source for nutrients, and the medium has little or no nutritional value.
Plants that are grown in water and not soil can be considered "hydroponically" grown. Hydroponics is the method of growing plants in water and not using a soil medium.
It is desirable because it is easier to prepare.
