Hydroponics: Hydroponic is the term use to describe the growing of plants without soil. Hydroponic growing hence means soilless growing. Hydro means “water” causing many people to think that hydroponic growing means growing that takes place in only water.
For many hydroponically grown foods, water-only growing is not the case. This is because hydroponically grown plants are grow in a variety of different media that act as soil substitutes. These media may include wood shaving, sand, gravel and vermiculite (Brentlinger, 2005).
The roots of the plants are anchore in the soil substitute and submerged in water containing a carefully-blended set of nutrients required by the plants. Plants that are grown hydroponically are often raised in greenhouses.

Temperature becomes easier to manage when using artificial lighting. Drafts and heating units should not be near the garden. The most favorable high temperature for a hydroponic patch is between 70 and 75 degrees Fahrenheit (Jeanroy, 2011).
Nutrients In hydroponics, nutritional needs are important as the method involves controlling all aspects of a plant’s growth. Since there’s no soil, all nutrition must come from the solution applied. The nutrients, called nutrient salts, are measured and dissolved in water which is then poured or pumped through the hydroponic system (Jeanroy, 2011).
Hydroponics is an important type of agricultural technology as it minimizes the use of limited land space. Although the cost of setting it up is high, the future of the agricultural industry lies with high technology farming (Jensen, 2010).
