The hydroponic method involves growing the tomatoes in a nutrient solution which contains all of the essential elements.
The practise of growing plants without the need for soil is known as hydroponics. Flowers, herbs, and vegetables grown hydroponically are planted in inert growing material and are then given nutrient-rich solutions, oxygen, and water throughout the growing process. The use of this technique results in accelerated growth increased yields, and improved quality. When a plant is growing in soil, the roots of the plant are always looking for the nutrients it needs to survive in order to provide for the plant's needs. If the root system of a plant is provided with direct access to water and nutrients, the plant does not need to expend any energy in order to maintain its own life. It is possible to focus the energy that the plant's roots would have spent obtaining food and water toward the growth of the plant instead. As a direct consequence of this, the development of new leaves and the blossoming of fruits and flowers are both stimulated.
