In layman's terms, hydroponics is the science of growing plants without soil-- although the plants may or may not be suspended in a solid medium such as gravel, or expanded clay balls. | In layman's terms, hydroponics is the science of growing plants without soil-- although the plants may or may not be suspended in a solid medium such as gravel, or expanded clay balls. | ||
Soil retains minerals and nutrients, which "feed" flora, as we all know. Plant roots can't absorb dirt, however; when water passes through soil, it dissolves and collects some of the nutrient particles embedded. This "food" solution is absorbable as a liquid. As you can see, the soil itself is not an integral part of a plant's feeding cycle-- it is simply a stabilizer for the roots, and a convenient filter. | Soil retains minerals and nutrients, which "feed" flora, as we all know.

Hydroponics is something that has interested me for quite a while. One of my projects a few years ago was based on the Deep Water Culture technique, where plants were suspended in a nutrient rich reservoir as an airstone aerates the roots. While this was sufficient, I couldn't grow anything but creepers and the reservoir was difficult for changing out the water. The experience and ideas stayed in the back of my mind over the past few years. | |||
