So What Actually is Hydroponics?

Hydroponics is a method of growing plants without the need for soil. With most plants in natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to make the plant grow; but the nutrients are. One of the major problems in growing plants in soil is knowing how much or how little to water the plants. Using the hydroponic method, plants have constant access to oxygen and to as much or as little water as they need. This ensures that the plant can regulate its own intake, depending on what it needs.
