Hydroponic Gardening – Let’s get introduced!

Agriculture industry is witnessing the need for change because of manifold issues like shortage of land, scarcity of water and labor issues. This need is for a technique which can produce maximum yield in minimal land, with less water, and lesser hassles. The answer to all these issues lies in one word- Hydroponics. Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool, or coconut husk. By studying and applying the techniques of advanced hydroponics, one can get flourishing, green vegetables and fruits in their own grow room.
Hydroponic gardening can be done in open spaces, orchards, grow rooms or even by using small objects like plastic trays, unused fish tanks and old barrels. You can use mediums like perlite, vermiculite, Rockwool, coconut coir, clay pellets, peat moss, sand, and even small pebbles. These media allow water and air flow to the roots of plants. Advanced hydroponics is practiced using many different systems. Some of the most preferred hydroponic systems in hydroponic growing gardening are:
Ebb and Flow system: This system is based on flood and drain technique. An air pump is used to flood the root zone of plants with water and organic hydroponic nutrients and with the help of air stone; you can create air bubbles and provide oxygen to the plants. Then water and nutrients is drained out of the root zone of plants. This pattern is repeated at regular intervals.
Wick system: This is one of the cheapest hydroponic growing systems. All you have to do is, take a cotton or nylon wick and place it in such a way that its one end is in contact with roots of the plants while the other one is dangling in the nutrient solution. With the capillary action of wicks, nutrients will reach roots of the plants.
Drip Irrigation System: This system works in the same way as ebb and flow system, however, in this system you can control levels of water and nutrients reaching plants roots and also you can decide the time for which roots are exposed to nutrients with the help of a timer.
Aeroponics: This is one of the most advanced hydroponics system. In this method, plants are grown in air or mist environment.
Many countries are encouraging research in the field of hydroponics as it is definitely the future of agricultural industry. However, as any technology, hydroponics too has its merits and demerits.
