This document discusses hydroponics, which is a method of growing plants without soil. It provides a brief history of hydroponics, describes the main types of hydroponic systems, and discusses the requirements for a hydroponic system including nutrients, lighting, and temperature control. It also outlines the advantages of hydroponics such as higher yields and faster growth compared to traditional soil-based agriculture and provides examples of plants that can be grown hydroponically. Finally, it describes how to create a simple hydroponic system at home using water bottles.

3. INTRODUCTION
• Hydroponics is a dirt-free, space saving ,water effective method of
soilless growing.
• Hydroponics is a Greek term ,made from 2 words that is:-"Hydro"
means water and "Ponos" means labour & hence "working water" is
it's actual meaning.
• Hydroponics is usually grown indoors/in a green house.
HISTORY
600b.c.
In the 600b.c. “Hanging gardens of Babylon” are believed to
havebeen one of the 1st mass scale hydroponics projects.
1000–1100
In 1000A.D.-1100A.D. ,the Azetects developed a system Of
floating gardens called “chinampas” in the island city of
tenochtitlan of Mexico.
1920s & 1930s
In 1920s & 1930s, Hydroponics terms coined by W.F.Gericke. He
experimented & popularised the practice of growing plants in a
water solution. Hence he termed this technique as Hydroponics.

WHAT IS HYDROPONICS SYSTEM ?

5. TYPES OF HYDROPONICS SYSTEMS
• .There are many different types of
Hydroponics systems are present .
These systems can be either
active/passive.
• '6'basic types of Hydroponics systems are
present ,they include:
1.The wick system
2.Deep water culture
3.Nutrient film technique
4.Ebb and flow
5.Drip system
6.Aeroponics

7. COMMON TYPES OF GROWING MEDIA USED
• 1.COCONUT COIR:-
• “Coconut coir”/“coco-tek” is also called
as “Cocopeat”,&“Ultrapeat” is an organic
material created from the coconut shell
husks.
• 2.ROCK WOOL:-
• This material is created by melting
rocks & spinning them into bundles
of filament fibers.

8. • 3.EXPANDED CLAY
PELLETS:-
• Most popular media
• Drain quickly & ph neutral
• Used in ebb & flow,water culture
technique.
• 4.STARTER PLUGS:-
• A strater plug can be defined as a
small,compact mass/ sample of a
solid growing medium,that is used
mainly for seed germination &
rooting cuttings.

9. • 5.GROWSTONES:-
• The porous rocks created from
recycled glass is a versatile
medium that can fit almost
hydroponic system.
• 6.VERMICULITE:-
• It is a mined material that is
made from expanded pebbles
under extreme heat.

10. • WHAT PLANTS NEED?
• Water
• Light
• Air
• Anchorage
• Nutrients
• NUTRIENT SOLUTIONS :-
• N:-Nitrogen for the production of leaves ,
stem growth & building plant cells.
• P:-”P” for the development of flowers ,
fruits & healthy root growth.
• K:-”K” For Photosynthesis.
• TRACE
ELEMENTS:-
• SULPHUR
• IRON
• ZINC
• MANGANESE
• COPPER
• BORON
• MAGNESIUM
• CALCIUM
• CHLORINE

11. • SYSTEM REQUIREMENTS:-
1.Ph
2.Electrical conductivity
3.Horticultural lighting
4.Temp. & Environmental Control
• WHAT CAN WE GROW?
• List of the hydroponics plants:-
1.Vegetable: lettuce ,spinach, tomatoes,
capsicum etc.
2.Herbs:-basil, oregano ,mint etc.
3.Fruits:-strawberries, hot peppers etc.

12. • HOW WE CAN GROW HYDROPONICS
GARDEN AT OUR HOME USING JUST WATER
BOTTLES:-
• To construct a home based hydroponics system from
our water bottles, we required some materials like:-
1.Plastic water bottle
2.Cutting equipment such as razor, blade, knife &
scissors.
3.A marker
4.Drill
5.Perlite/other growing media
6.Water resistant tape
7.Cotton yarn/other such wicking product
8.Water, nutrient solution for herbs & a liquid

13. • ADVANTAGES:-
• High yields achieved in a smaller space.
• Nutrients precisely controlled.
• 30-55% faster growing than the soil
growing plants.
• Indoor gardens grown using full-
spectrum horticultural lighting.
• Soil-borne pests & diseases are
eliminated.
• Weeds are eliminated.
• Plants are healthier & reach maturity
faster.
• Can farm all year round.
• DISADVANTAGES:-
• Cost of initial investment.
• Production is management & labour
intensive.
• A high level of expertise is
required.
• Daily attention is necessary.
• Specially formulated, soluble
nutrients must always be used.
• Some water-borne diseases can
rapidly spread in recirculation
system.

14. CONCLUSION
• Progress hasbeen rapid & results
obtained in various countries have
proved that this technology is
thoroughly practical & has very
definite advantages over
conventional methods of crop
production.
• The main advantages of soil-less
cultivation is the much higher
crop yields & we also get so much
tasty & good quality of vegetables
& fruits as well.
• Now-a-days people living in
crowded city streets, without
gardens. By using this technique
they cultivate any types of herbs
at their home/terrace & that’s to
