INTRODUCTION
 “Cultivation of plants in water”
 It is technique for growing plants without soil.
Utilizing this technology, the roots absorb balanced
nutrient dissolved in water that meets all the plant
developmental requirements.
 Many aggregates and media support plant growth
 Also called as “ the cultivation of plants without
using soil.”
4
HISTORY OF HYDROPHONICS
 Hydroponics became popularized by the news
media in the 1920s when a scientist named Dr.
William F. Gericke of the University of California
when he put laboratory experiments in plant
nutrition on a commercial scale. So he termed
these nutriculture systems HYDROPONICS.
 The word was derived from the Greek words,
HYDRO (water), and PONOS (labor), literally
“water working”.
5
WHAT IS HYDROPONIC SYSTEM ?
Photosynthesis process:
Carbon Dioxide + Water → Glucose + Oxygen
6CO2 + 6H2O → C6H12O6 + 6O2
There is no mention of "soil" anywhere in there
and that's all the proof you need that plants can grow
without it.

HYDROPONICALLY ?

7
 Benefits sometimes questioned…..
 Some hydroponic growers got many times greater
yields than conventional methods.
 Because hydroponically grown plants dip their roots
directly into nutrient-rich solutions, they get what
they need much more easily than plants growing in
soil.
 With smaller roots, you can grow more plants in the
same area and more yield.
 Many pests are carried in soil, so doing without it
generally gives you a more hygienic growing system
with fewer problems of disease.
8
HOW DOES HYDROPONICS
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).

TYPES OF HYDROPONIC SYSTEM
1. Wick System
2. Water Culture
3. Ebb & flow (Drain and flow)
4. Drip system Recovery/ Non-
recovery
5. N.F.T.(Nutrient film Technique)
6. Aeroponic system

13
6. AEROPONIC
14
MATERIALS USED IN
HYDROPONICS
1. Coco Coir
Has an excellent air to
water ratio with great
water retention
15
2. Rockwool
 A fibrous material
made from melted
rock .
 Not Biodegradable
 Hazardous to health
 Must be pH balanced
 Excellent water
retention.
16
3. Expanded clay Pellets
Most popular media
 Drain quickly & ph
neutral
 Reusable
 Used in ebb & flow,
water culture
 50/50 mix of clay and
coco creates a
breathable medium
 Heavy
17
4. Potting soil (Perlite)
 Perlite + Coco Coir +
Vermiculite
 Synthetic materials
 are puffed/ heated to
produce light and porous
material
18
Nutrient Solutions
 In Hydroponics, nutrient control is easy
 A nitrogen-rich Grow Formula
 A phosphorous and potassium-rich Bloom Formula
& The results?
Bumper crops of delicious fruits and vegetables every
time.
19
 Plants require 17 essential elements to grow
and reproduce
 The first three are Hydrogen, oxygen and
carbon
 Other 14 are:
Macro-Elements: Nitrogen, Phosphorous,
Potassium, Calcium, Magnesium, Sulfur
Microelements: Iron, Manganese, Copper, Zinc,
Boron , Chlorine, Molybdenum, Nickel
20
SYSTEM REQUIREMENTS
 pH Control
5.8 and 6.4, or slightly acidic
 Electrical Conductivity (EC)
1.2-3.5 Mho
 Horticultural Lighting
Metal Halide (MH), High Pressure Sodium
(HPS) lamps.
 Temperature and Environmental Control
68- 78 degrees F.
21
ADVANTAGES
 Higher yields achieved in a smaller space.
 Nutrients precisely controlled.
 Grow, bloom and boost formulas used at the
appropriate growth stage.
 Indoor gardens grown using full-spectrum
horticultural lighting.
 Soil-borne pests and diseases are eliminated.
 Weeds are eliminated.
 Plants are healthier and reach maturity faster.
 Automation is possible
22
DISADVANTAGES
 Cost of initial investment
 Production is management, capital and
labor intensive.
 A high level of expertise is required.
 Daily attention is necessary.
 Specially formulated, soluble nutrients must
always be used.
 Some water born diseases can spread
rapidly in recirculation system.
23
WHAT CAN WE GROW ?
24
WE CAN GROW
HYDROPONIC GARDEN AT
OUR HOME ….
USING JUST WATER
BOTTLES
25
WHAT WE ARE BUILDING…

27
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
much higher crop yields.
People living in crowded city streets, without
gardens, can grow fresh vegetables and barren and
sterile areas can be made productive at relatively low
cost.
