What’s the point of growing my plants using hydroponics rather than in the ground?

In hydroponics, the plant receives all of the nutrition it needs directly, according to its stage of development. As the plant has no need to search for its food, it will grow fewer roots and put all of its energy into producing more leaves, flowers and fruits. It is thought that, by using hydroponics, you can achieve up to 30% greater production than in the ground.
