Hydroponics is a science of growing plants using a solution of suitable nutrient instead of soil. This can be either be through the use of non-soil growing media or no growing medium at all.
The growing medium, if any, is totally inert or merely acts as a support for the plants & their root system, while the nutrient solution passes freely. There are several different types of hydroponic systems but all share same basic method of supplying the plant nutrients with water.
Now, I will give explanation about the types of hydroponics systems on which we are working.
