 Hydroponicsissimplytheproductionofcropswithoutsoil.
 Hydroponics is also an answer to two of the world's growing
concerns:diminishingsoilquality,andwaterscarcity.
 It is technique for growing plants in
water. Utilizing this technology, the roots absorb balanced
nutrient dissolved in water that meets all the plant
developmentalrequirements.
 Manyaggregatesandmediasupportplantgrowth

5. HISTORY
 Hydroponicsbecamepopularizedbythe news media in
the 1920swhen a scientistnamedDr. William F.
Gerickeof the University of California when heput
laboratory experiments in plant nutrition ona
commercial scale.Sohetermed thesenutriculture
systems HYDROPONICS.
 Theword wasderived from the Greekwords,
HYDRO(water), andPONOS(labor), literally “water
working”.

6. •Hydroponic principles used in the creation of the Hanging
Gardens of Babylon600BC
•Marco Polo records sightings of floating gardens in ChinaLate 1200S
•Francis Bacon, British scientist, studies soil-less gardening.
Publication of his work sets of a wave of hydroponic research1620
•John Woodward, British scientist, concludes plants grow better in
water with nutrients, opposed to distilled water.1699
•William Gericke, Berkeley scientist, demonstrates the benefits of
soil-less gardening. Credited for giving hydroponics its name1930
• Two other Berkeley scientists, Dennis Hoagland and Daniel Arnon, publish "The
Water Culture Method for Growing Plants Without Soil," most important text
regarding hydroponics. Developed three nutrient solutions that are still used today
1938

8. WHYTOGROWTHINGS
HYDROPONICALLY?

9.  Benefitssometimes questioned…..
 Somehydroponicgrowersgotmanytimesgreater yieldsthan
conventional methods.
 Becausehydroponicallygrownplantsdiptheir roots directlyinto
nutrient-rich solutions,they getwhat they needmuchmore
easilythan plantsgrowingin soil.
 With smallerroots,youcangrowmoreplantsinthe samearea
andmore yield.
 Many pestsare carriedinsoil,sodoingwithout it generally
givesyouamorehygienicgrowingsystem with fewer problems
of disease.

10. HOWDOESHYDROPONICS WORK?
 Stand your
plants in a
plastic trough
and let a
nutrient
solution trickle
past their roots
(with the help
of gravity and a
pump).

12. TYPESOFHYDROPONICSYSTEM
Wick System
Water Culture
Ebb & flow (Drain and flow)
Drip system Recovery /Non recovery
N.F.T.(Nutrient film Technique)
Aeroponic system

13. 1. WICKSYSTEM
 The nutrient solution is pumped from the reservoir up the growing tray and delivered
to plant roots via the capillary movement of the wick

14. 2. WATERCULTURE
 Plants are placed in a net pot and are held by a floating platform above a container of
nutrient and water. Plant roots are suspended and stretched into the nutrient-rich
oxygenated solution

15. 3. EBB& FLOW (DRAINANDFLOW)
 Also known as Flood & Drain. The system floods the nutrient solution onto the grow
tray to surround plant roots before draining back. Often automated by a pump
connected to a timer.

16. 4. DRIPSYSTEM
 Drip system pumps the nutrient solution through the tube and drops onto plant roots
via a network of drip lines. The action is often made automatical by a timer

17. Nutrient Solutions
 In Hydroponics,nutrient control is easy

Bumpercropsof deliciousfruits andvegetablesevery time.

18.  Plantsrequire 17 essential elements to grow and
reproduce
 Thefirst three are Hydrogen,oxygenand
carbon
 Other 14 are:
Macro-Elements: Nitrogen, Phosphorous,
Potassium,Calcium,Magnesium, Sulfur
Microelements: Iron, Manganese, Copper,Zinc,
Boron, Chlorine, Molybdenum, Nickel

19. SYSTEM REQUIREMENTS
 pHControl
5.8 and6.4, or slightly acidic
 ElectricalConductivity (EC) 1.2-3.5 Mho
 Horticultural Lighting
Metal Halide (MH), HighPressureSodium (HPS)lamps.
 TemperatureandEnvironmentalControl 68- 78
degrees F.

20. ADVANTAGES
 Soil is not required
 Water remains in the system and can be reused, thus saving water
 Nutrition levels are controlled, thus reducing nutrition
requirements and costs
 The controlled hydroponic environment ensures that no pollution
from the nutrients is released
 Plants are healthier with high yields
 The container is movable, thus pests and diseases can be easily
controlled
 Easy harvesting with shorter harvest time
 Hydroponic plants are better for consumption
 There is no damage due to pesticide

21. DISADVANTAGES
 Cost of initial investment
 A high level of expertise is required.
 Daily attention is necessary.
 Specially formulated, soluble nutrients must always be used.

24. CONCLUSION
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.
The main advantages of soil-less cultivation is the
muchhighercrop yields.
People living in crowded city streets, without gardens, can
grow fresh vegetables and barren and sterile areas canbe made
productiveat relatively low cost.
