Hydroponics

INTRODUCTION

Hydroponics is always soil less culture, but not all soil less culture is hydroponics."hydroponics" is the growing of plants without soil.  The term "soil less culture" is more appropriate since it covers all types of planting technologies without soil. When most people think of "hydroponics"' they think of plants grown with their roots suspended directly into water with no growing medium. 

Why Soil less Culture Works Better

With soil less culture, the plants are grown in an inert growing medium where the plants do not get anything from the growing medium. 

The plants receive only what  you give them and nothing else.  You have complete control over the pH, nutrients contents and the nutrient strength.  In the soil, you really have no idea what the plants are getting.  So farming becomes a big guessing game.  

What Is "Growing Medium"?

growing medium is simply what the roots of the plants are growing in.  This can be a visit variety of materials, including coconut fiber, gravel, sand or any number of other materials.  Even air can be a growing medium.

The growing medium is an inert substance that doesn't supply any nutrition to the plants.  There are 6 basic types of soil less culture systems, namely:

        1.    Wick    2.    Water Culture    3.    Ebb and Flow (Flood & Drain)    4.    Drip (recovery or non recovery)    5.    N.F.T. (Nutrient Film Technique)    6.    Aeroponics

ADVANTAGES OF THE SOIL LESS FARMING

 plants can be grown anywherebetter control over plant growth Less work with soil less farming Water and nutrients are conserved pest and disease problems are reduced culture is extensiveTransplanting shock is reduced for

seedlings

DISADVANTAGES OF SOIL LESS FARMING

starting cost is high sound technological know how is required for

proper training. The mediums require some sort of container The nutrients have to be mixed in water and then

applied to the plants Hydroponic cultivation usually requires more

capital investment than soil cultivation Some water bourne diseases can spread rapidly in

recirculating system

CONCLUSIONSoil less farming has advantages

and disadvantages. The advantages can conserve our environment. As a conclusion, soil less farming has benefit if compare to soil culture.
