2. INTRODUCTION
 The word was derived from the Greek words, HYDRO(water), and
PONOS(labor), literally “water working”.
 Hydroponics is the technique of growing plants using a water-
based nutrient solution rather than soil. Also can include an
aggregate substrate, or growing media, such as vermiculite, coconut
coir, or perlite. Hydroponic production systems are used by small
farmers, and commercial enterprises.
 Cultivation of plants in water.
 Also called as “ the cultivation of plants without using soil.”

7. AEROPONICS SYSTEM

8. ADVANTAGES
They produce between three and ten times more
food than conventional agriculture in the same
space.
 They are safe from weeds and insects, making
unnecessaries the use of these products.
 It consumes 20 times less water than
conventional agriculture, A as the water is
recirculated and reused.
 Automation is possible.
 Plants are healthier and reach maturity faster.
 Nutrients precisely controlled.

9. DISADVANTAGES
 Cost of initial investment.
A high level of expertise is required.
Daily attention is necessary.
Some water borne diseases can spread
rapidly in recirculation system.
Production is management,capital and
labor intensive.

10. MATERIALS USED IN HYDROPONICS
1.Coco coir :
Has an excellent air
to water ratio with
great water retention

11. ROCKWOOL
Must be pH balanced.
Hazardous to health.
A fibrous material made from
melted rock.
Non Biodegradable.
Excellent water retention.

12. Potting soil ( Perlite)
Perlite + Coco Coir +
Vermiculite
Synthetic materials.
Are puffed/heated to
produce light and porous
material.

13. Expanded clay pellets
Most popular media.
Heavy
Drain quickly and pH neutral.
Reusable
Used in ebb & flow, water culture.

14. SYSTEM REQUIREMENTS
pH Control
5.8 and 6.4,or slightly acidic
Horticultural Lighting
Metal Halide(MH), High Pressure Sodium(HPS) lamps.
Electrical conductivity
1.2-3.5 Mho
Temperature and Environmental Control
65-75 degrees F.

15. CONCLUSIONS
Progress has been rapid and results obtained in various
countries have proved that this technology is thoroughly
practical and has very definite advantages over conventional
methods of crop production.
