It often comes as a surprise that a plant grown in the absence of soil is able to grow and thrive much better than it is in the presence of soil.

One of the reasons for this is that plants use a tremendous amount of energy available to them to produce a large root system. This is in the plants’ best interest since without roots, it can not absorb water and nutrients in the soil, which in turn means it cannot thrive. An extensive root system means more access to nutrients and water.

In hydroponics gardening, all of the nutrients and water the plant needs are provided on a continuous basis through the nutrient solution. This means that the plant only needs to develop a root system to the level that it needs to absorb enough nutrients for its current state of growth. It does not need to produce a large root system to go out seeking nutrients and water.

Evidence for the fact that hydroponic plants are not producing large root systems can be seen by examining the roots closely. Plants in soil have tiny hairs along the entire root system, which serve to seek out water an nutrients. Hydroponic plants on the other hand don’t have these tiny hairs, meaning they have sufficient water and nutrients for their needs, and don’t need to go seeking any more.

Instead of investing energy in their root systems, hydroponic plants can instead invest their energy into vegetative growth, flowering, and fruit production.
