What is hydroponics 

Hydroponics is defined as growing plants, using mineral nutrient solutions, without soil.

Although hydroponic systems do not involve soil, they may involve a wide variety of growing media, such as perlite,

gravel, peat, sand, rockwool and others.

Typical hydroponic crops include lettuce, strawberries, hebrs, tomato, cucumber and flowers.

In hydroponic systems which do not involve any growing medium, roots are immersed in an aerated nutrient solution.

In hydroponic systems, most of the plant nutrients are supplied by the nutrient solution, rather than by the media

in which the plants are grown.

Unlike soil, that stores nutrients, the growing media used in hydroponic systems have a little effect, if any, on the

 nutrition of plants. As a result, the only source of nutrients is the nutrient solution, and therefore you have total control

 over your plant nutrition.

While soil allows more tolerance for inaccuracy, hydroponics leaves very little room for errors. Because changes

are rapid and mistakes can be very costly, hydroponics growers should make highly educated and accurate decisions. 

Greenhouse Hydroponics Advantage

Some of the reasons why hydroponics is being adapted around the world for food production are the following:

• No soil is needed for hydroponics

• The water stays in the system and can be reused - thus, lower water costs

• It is possible to control the nutrition levels in their entirety - thus, lower nutrition costs

• No nutrition pollution is released into the environment because of the controlled system

• Stable and high yields

• Pests and diseases are easier to get rid of than in soil because of the container's mobility

• It is easier to harvest

• No pesticide damage

• Plants grow healthier

• It is better for consumption

Greenhouse Hydroponics Disadvantage

Without soil as a buffer, any failure to the hydroponic system leads to rapid plant death. Other disadvantages

 include pathogen attacks such as damp-off due to Verticillium wilt caused by the high moisture levels associated

with hydroponics and over watering of soil based plants. Also, many hydroponic plants require different fertilizers

 and containment systems
