Any plant needs sunlight, water and nutrients to grow. But even in special conditions and controlled climate, the plant can be grown only in water, sand, or pebbles. Hydroponics is a technique in which a plant or any type of crop is grown only in water, sand, or pebbles even in a controlled climate.
Hydroponics is a method that uses a solution for growing plants instead of using soil. There are many ways to use this technique and it is very useful.
Types of Hydroponic Systems?
There are Manny of hydroponic methods, we tell you about some hydroponic methods
It uses a system where plant roots are contained in a chamber that is sprayed continuously or intermittently with a fine mist of nutrient-rich water.
The roots of the plant are suspended in the air and the advantage of this system is that the roots have good access to oxygen. The system was invented by Richard Spooner in 1983 and has become a successful method of growing a wide range of crops including seed potato production, tomato production, leaf crops and small lettuces.
This system does not use electricity to circulate the nutrient-rich water.
2) Gravity fed system
The system consists of a container larger than the plants and the water moves through and down the plants in a controlled manner. This system is used with plants that are grown in pots and the water is channeled to the base of the pot and capillary action draws the water into the pot.
t involves growing plants suspended in water with nutrients. The plants are placed in the net with their roots in the water.
3) Deep Water Culture Systems
The net may or may not contain material to separate the roots. The water pumps air through it to increase the oxygen in the water which helps the roots to grow.
it is not that this is a technology of today, which was developed only a few years ago. Based on historians and relics, this technique is very old and well used.
History of Hydroponics
It was first started in history in the “Babylonian Empire”. At that time this type of technique was also used in hanging gardens. It is still very prevalent in Iraq.
