A P.P.T containing with a gist of whats hydroponics, it's functioning, different methods of the hydroponic system, real-life implementation of it, along with basic requirements for Hydroponics Culture.

1. Biology :-
Hydroponics

Grade :- X - B

2. Introduction
 The word was derived from the Greek words, HYDRO
(water), and PONOS (labor), literally “water working”
 Many aggregates and media support plant growth. Also
called as “ the cultivation of plants without using soil.”
 “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.

3. What's hydroponic System
 Photosynthesis Process :-
 There is no mention of "soil" anywhere in there and that's all
the proof you need that plants can grow without it

4. Why to grow plants hydroponically ?
 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.
 Many pests are carried in soil, so
doing without it generally gives
you a more hygienic growing
system with fewer problems of
disease.

5. Types of hydroponic system :-
 1. WICK SYSTEM 2. WATER CULTURE


6. TYPES OF hydroponic SYSTEM :-
DRIP SYSTEM N.F.T.
(NUTRIENT FILM TECHNQUE)

7. Hydroponic system requirements:-
 PH control
 5.8 & 6.4 or slightly acidic
 Electrical Conductivity (EC)
 1.2 - 3.5 Mho Metal halide (MH), High Pressure Sodium (HPS)
lamps.
 Horticultural lighting
 Metal halide (MH), High Pressure Sodium (HPS) lamps.
 Temperature and Environmental control
 68–78 degrees F.

9. Disadvantages of hydroponic system
 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.

13. 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.
