Hydroponics, What It Is All About

In very simple terms, hydroponics can be described as the growing of plants without soil. Plants require four basic things in order for them to grow: water, nutrients light, and an anchor for the roots. While three of these elements come from the soil, please know that the soil isn't where the nutrients come from, rather, from the water in the soil. When you provide a water-nutrient solution as well as some light for the plant, what you just actually need is an alternative medium - aside from soil - to grow your plants.

While hydroponics is developed as a new science, it's definitely not a new concept. The Hanging Gardens of Babylon, for example, is a wonderful and fine example of hydroponics; pieces of evidence of the said practice were also found in the histories of China, Egypt and the Aztecs.

Given that there is a lot of soil around, isn't it a bit a preposterous idea to grow plants without soil? Certain situations, on the other hand, would make growing food hydroponically the better alternative. For one thing, this method can be used to grow food outside the time frame the normal growing season, because it isn't dependent on the weather. Secondly, the process is not reliant on sunlight; natural lighting works fine, but artificial lighting can be utilized too. Lastly, and perhaps most importantly, hydroponics provides hope for growing plants in nations where soil is contaminated.

In theory, hydroponics enables us to grow food in instances when it's potentially impossible to do so: in the dead of winter, in Arctic regions and even in space! All we need is to provide the four elements that plants need for growth all of which can be provided without soil.

These days, it's not only the scientists that are examining the use of hydroponics. Nations such as Canada and Holland are now using this method significantly to grow food. A few individuals are also maintaining hydroponic gardens at home. As a result, there is an increased demand in hydroponic products - due largely to the increase in awareness of this practice. While this won't completely replace the old-fashion ways of the soil, hydroponics will definitely provide us with a wonderful alternatives to agriculture.
