Information About Hydroponics
Various pollutants that we are exposed to in plant soil may remain in our bodies even several years after exposure. This fact, and others, has encouraged researchers to study ways in which we may limit the plant’s exposure to mediums that can contribute to a person’s poor health. Hydroponics is a gardening method which does not require soil as a planting medium.
Soil Is Not Important
Researchers have discovered that plants primarily use soil as a reservoir where water and nutrients may be stored for later consumption. Even plants that are usually found growing in soil, terrestrial plants, can survive without dirt as long as they have access to the nutrients necessary to their growth.
Hydroponic gardening replaces the soil medium with materials that may be more suitable for human health; such as, wool, perlite and gravel. These provide stability for the plant’s roots without the contaminates that are sometimes found lingering in soil.
The most important factor to be considered in hydroponic gardening is the mineral solution that replaces the natural reservoir found in soil. Usually provided in a water reservoir, the nutrients fed to the plant must be carefully measured to meet the specific needs of the plant. And, because few plants can tolerate constant exposure to the water reservoir, the solution must also be administered in calculated doses.
Hydroponic gardening has the advantage of a clean environment not dependant on the mess and fuss of soil. The absence of soil also guarantees the absence of soil borne pathogens that may affect the plants and produce being grown. The clean, orderly design of a hydroponics growing system makes it an ideal option for dry climates with a limited growing season; a hydroponic system can be easily constructed in a greenhouse or home and will provide healthy crops without the excess and weight of soil.
