Soil is an essential source of nutrients and minerals for growing plants.

Soil is an essential source of nutrients and minerals for growing plants. Also, it is responsible for facilitating gaseous exchange between the atmospheres and roots and helps to protect plants against erosion and facilitates water retention. However, this article discusses a system – hydroponics, wherein plants can be grown without soil. Read on to find out what is hydroponics and gain valuable information about it. What is Hydroponics? The hydroponics definition states that it is the cultivation of plants in water. It is a subcategory of hydroculture and is a useful technique of growing plants without soil. Through this technique, roots absorb the nutrients present in water and fulfil their growth requirement. Furthermore, through this method, one can grow plants in liquid, sand or gravel by simply adding some nutrients to it. In recent years, hydroponics has found application in the field of commercial production and horticulture. Similarly, residents of cities with limited space is using this method to grow fresh plants in their home and surroundings. In hydroponics, the photosynthesis process is expressed as – Carbon dioxide + Water = Glucose + Oxygen or, 6CO 2 + 6H 2 O = C 6 H 12 O 6 + 6O 2 Some of the most common hydroponics examples include – the production of artichokes, sprouts, cabbage, peas, onions, tomatoes and yams.

Types of Hydroponics Systems Here are the different types of hydroponics systems.

Other than these, the nutrient film technique and aeroponic system are also popular types of hydroponics systems.

Advantages of Hydroponics Following advantages makes the uses of hydroponics more feasible and effective –

Irrespective of its benefits and uses, hydroponics has its share of disadvantages too. Read below to find remaining hydroponics information and its prominent problems. Disadvantages of Hydroponics  Here are the prevalent problems of hydroponics –

Ans. In simple words, hydroponic is a technique of growing plants without soil. It is a subcategory of hydroculture, which uses mineral nutrients solution to grow plants like peas, artichokes, cucumber, onions, radishes, leeks, etc.

Ans. Hydroponics helps to increase crop production even in areas where the soil is sterile. Also, the crops thus produced are healthier and less susceptible to pests and diseases. Similarly, hydroponics helps to use small places effectively for cultivation.

Ans. The advantages include an increased yield of crops, more nutritious and fast yield and ease of cultivation.
