hydroponics
Hydroponics is a method of growing plants using mineral nutrient solutions, in water without soil. Soil less growing media includes rock wool, pottery shards, glass marbles, special porous and inert clay pellets. Soil less growing medium also includes coir fiber, perlite, vermiculite and gravel. Even polystyrene packing peanuts or any other inert material not toxic to plants and not subject to decomposition is a soil less growing media as well.
The reasons why hydroponics is being adapted around the world for food production are as follows.
1. No soil is needed for hydroponics and the water stays in the system and can be reused, thus lowering the water costs.
2. Through hydroponics, it is possible to control the nutrition levels in their entirety, thus lowers the nutrition costs. Hydroponics also helps to maintain no nutrition pollution is being released into the environment because of the controlled system.
3. Hydroponics offers Stable high yields and easier to harvest.
4. Hydroponics helps to get rid of pests and diseases easier of than in soil because of the container’s mobility and no much pesticide damage.
Now a days there is a rapid progress in the hydroponic way of farming. Results obtained from various parts of the globe clearly indicates that this is more effective and practical. Hydroponics has a lot of advantages and high yield when compared to conventional methods of farming.
Hydroponics stands apart as it can be used in places where in-ground agriculture or gardening is not possible. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium such as perlite, gravel and mineral/rock wool and expanded clay. Compared to any other growing medium Coco peat is the most suitable and commonly available growing medium.
