Hydroponics refers to the soil-less method of growing plants. When soil is not used to grow plants, gardeners can use limited space to grow more quantities of plants. The nutrient needs of the plant are met with the help of a growing medium, water and liquid fertilizers.
So, how does hydropinc gardening work? Usually, in this method of growing plants, the gardener has more control over the environment in which the plants are grown. Though it requires more checking and monitoring, the gardener endeavors to provide the optimum growing environment to the plant without making use of soil. To ensure that the plants survive, water, sunlight and minerals are needed in traditional gardens. However, in hydroponics, the sunlight is provided with artificial or natural light, while the growing medium allows the plant to absorb moisture, minerals and carbon dioxide to produce food and release oxygen into the air.

There are many advantages and disadvantages of hydroponic gardening. The advantages are that the gardener has total control of the amount of nutrients and minerals to include into the growing medium and meets these needs during the different growth stages of the plant. (See Reference 1) As there is no soil present, there are less chances of insects and other pests attacking the plants, and this also ensures that no problems associated with weeds occur. The growing medium, which is invariably water, allows proper addition of fertilizers and this, in turn, helps to increase the yield of the plant. (See Reference 1)
The major disadvantage of hydroponics is that it is cost prohibitive as the hydroponics system and methods to monitor the plants and introduce fertilizers are expensive. Also, if pests attack the plants, then the damage is quite severe and expensive. (See Reference 1)
