REFERENCE

WHAT IS HYDROPONIC?Hydroponics comes from the Latin language and it means working

water.

"hydro" means "water"

"ponos" means "labor".

Hydroponics is steadily growing in popularity throughout the world.

There are many reasons for this. First of all it is an eco-friendly

method of cultivation since it minimizes use of water and potentially

harmful chemicals.

Hydroponics is a subset of hydroculture and is a method of growing

plants using mineral nutrient solutions, in water, without soil.

Terrestrial plants may be grown with their roots in the mineral nutrient

solution only

HOW DOES IT WORK? Plants are suspended in a ph neutral medium

Nutrient rich water is pumped through allowing the plants to absorb what they need

An air pump oxygenates the water for the roots

The water is recycled, until the nutrients are nearly all absorbed by the plants and then disposed of in a responsible way

WHERE CAN WE USE IT? Households – to enhance self sufficiency

Schools – to empower our next generation

Commercial production – more sustainable,

Communities – eliminate food oases and create

resiliency

Urban Agriculture – fits perfectly in areas with

population density

WHO SAID WE NEED SOIL TO CULTIVATE??

Hydroponics technology is a green technology that makes use of the natural plant growth phenomena in obtaining better results from plants. Industries such as the airlines and fast-food chains use hydroponically grown vegetables. The cut flower industry, nurseries and the pharmaceutical industry are other sectors where this technology is being practiced successfully.

The project was launched in the country in October last year and an awareness programme was mooted in Bangalore. Till now, 126 students from Jabalpur,

Jamshedpur, Gujarat, Nagaland and Delhi have been trained in the practice.

HISTORY

The process of hydroponic growing in our ocean goes

back to about the time earth was created.

Many different civilizations have utilized hydroponic

growing techniques throughout history.

Egyptian hieroglyphic records date back several hundred

years B.C. describe the growing of plants in water.

Hanging gardens of Babylon, somewhere in (Iraq)

NUTRIENTS NEEDED FOR PLANT LIFE

Nitrogen

Phosphorous

Potassium

Sulphur, Calcium, Magnesium

Copper, Boron, Zinc, Manganese

IS PH IMPORTANT IN HYDROPONICS?

The control of pH is extremely important, not only in hydroponics but in soil as well. Plants lose the ability to absorb different nutrients when the pH varies. (This topic is answered in much greater detail in the "mini-class" on pH in Hydroponics).

The ability to quickly and easily test and control pH in hydroponics is a major advantage over dirt gardening, where testing and adjusting the pH is much more complicated and time consuming.

PH

COMMONLY USED GROWING MEDIA FOR HYDROPONIC CULTURE:

Coconut Fiber

Expanded Clay

Perlite

Rockwool

Sand

Vermiculite

ADVANTAGES OF HYDROPONIC

Superior taste, quality, appearance, uniformity, and extended shelf life of hydroponic vegetables.

No sterilization of growing media required and plant nutrition is easily and completely controlled within the nutrient reservoir.

No cultivation, no soil borne diseases or insects. Allows uniform water availability to plants.

Closer plant spacing is possible and movable plant channels allow greater production from equal areas

Less water required and less fertilizer needed, and root zone heating and cooling is made possible.

DISADVANTAGES OF HYDROPONICS

Limited production in comparison to field conditionsInitial setup cost is high.

As the necessary equipments are expensive Technicalskill is required to maintain the equipments.

Hydroponic gardens are influenced by power cut.

If a disease appears all plants in the container will beaffected.

Water borne diseases can quickly spread right throughthe hydroponic gardens If the hydroponic system failsit can leads to rapid plant death and losses

BASIC HYDROPONIC SYSTEMS AND HOW THEY WORKThere are 4 basic types of hydroponic systems;

Wick,

Water Culture,

Ebb and Flow (Flood & Drain),

Aeroponic.

There are hundreds of variations on these basictypes of systems, but all hydroponic methods are avariation (or combination) of these four.

SYSTEMS:

WICK SYSTEM

The Wick system is by far the simplest type of hydroponic system. Thisis a passive system, which means there are no moving parts. Thenutrient solution is drawn into the growing medium from the reservoirwith a wick.

WATER CULTURE

The water culture system is the simplest of all activehydroponic systems. The platform that holds the plants isusually made of Styrofoam and floats directly on thenutrient solution. An air pump supplies air to the air stonethat bubbles the nutrient solution and supplies oxygen tothe roots of the plants.

EBB & FLOW - (FLOOD AND DRAIN)

The Ebb and Flow system works by temporarily flooding the grow tray with nutrient solution and then draining the solution back into the reservoir. This action is normally done with a submerged pump that is connected to a timer.

When the timer turns the pump on nutrient solution is pumped into the grow tray. When the timer shuts the pump off the nutrient solution flows back into the reservoir. The Timer is set to come on several times a day, depending on the size and type of plants, temperature and humidity and the type of growing medium used.

AEROPONIC

The aeroponic system is probably the most high-tech type of hydroponic gardening. The roots hang in the air and are misted with nutrient solution. The misting are usually done every few minutes. Because the roots are exposed to the air, the roots will dry out rapidly if the misting cycles are interrupted

CONCLUSIONSpecially, in a country like INDIA, adopting soil-less culture to help improve the yield and quality of the produce so

that we can ensure food security of our country.

This has been a potential issue for years which is why scientists have developed another way to grow food an plants

WITHOUT UTILIZING LAND which is a fast depleting resource

If you have the knowledge and the right equipment you can do it yourself out of your HOME. This means that

individuals can stop slogging down to the grocery every day.

Hydroponics is popular not just as way to produce larger, healthier, and more flavourful foods on a large scale, but also

as HOUSEHOLD HOBBY.

Simple hydroponic systems can help people grow herbs, flowers, or vegetables in their basement, in a large closet or

even on their KITCHEN COUNTER.

Many people LOOK TOWARDS hydroponics as the way the most food may be grown in the future.

Hydroponics may be the answer to sustaining the world's food supply because of its ability to produce larger yields

using a smaller amount of space.

NASA has experimented with hydroponics as a means of growing vegetables in space. Working on it still.

The great thing about hydroponics growing that ANYONE can do it
