GENERAL FACT• Any plan can be grown in a hydrophonix system• Almost any system will produce acceptable
growth• Small scale is entirely different from the culture
of several thousand plants• Has constributed much to understanding plant
growth• Very few comercial producers• Most facilities are experimental studying plant

Estimate the size of the area you will need.
For example, a combination of 66 cabbage & Silver beet can be grown in 5 pipes of 4 inch round and 3 meters long by 2 meters wide. The whole unit is therefore 6 meters square.

ADVANTAGES
• There is absolutely no soil required.• Water used in the system remains confined and
reused, hence saving costs of watering or irrigation.• Nutrition levels are manually regulated so it’s easy
to save on relative costs.• Production is high and reliable.• Safety from pests and diseases is ensured, much
due to portability of containers.• It’s not as cumbersome and dirt-prone as where
soil is involved.

conclusion
Hydroponic is the method of growing plants in water to which special chemicals are added, rather than growing them in earth. It can be done in our back yard and so forth. Having this system will help our vegetables need. It is not expensive and environmentally safe that every one can do it.
