Substrate Culture
The root of the crop is fixed to an organic or inorganic matrix in, by drip irrigation or trickle irrigation methods, crop nutrient solution supply. Growing media can be loaded into a plastic bag, or in the ditch or tank cultivation. Cultivated in nutrient solution matrix is a not circulating, called open system, this prevents the nutrient solution circulating through the disease spread.
Substrate cultivation buffering capacity, water conflicts, between nutrients and for O2 does not exist. Equipment is simple, low cost, high harvest, widely used in production.

Basic Information     

What are the Hydroponic

Hydroponics is a subset of hydroculture and is a method of growing plants

using mineral nutrient solutions, in water, without soil. Terrestrial plants

may be grown with their roots in the mineral nutrient solution only or in

an inert medium, such as perlite, gravel, mineral wool, expanded clay

pebbles or coconut husk.

 

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 Indoor hydroponics growing system 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
