Today Indian farmers face the following challenges
Drought conditions and unpredictable weather
Rising temperatures
Polluted water systems
Lack of irrigation
Poor water management
Under-nourished or over nourished crops
India today needs food security which entails that all people at all times have physical and economic access to safe and nutritious food to meet dietary needs.
Lack of water for agriculture leads to production of lesser food which means more hunger and malnutrition
We are going to highlight the need for technology in agriculture that can contribute towards water savings and have a positive impact on food production and availability.
Hydroponics is one methodology of soil-less cultivation.
It is a method of growing plants using mineral nutrient solutions, in water, without soil.
The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum by Francis Bacon.
Some of the reasons why hydroponics is being adopted around the world for food production are the following:
No soil is needed for hydroponics
The water stays in the system and can be reused
It is possible to control the nutrition levels accurately
It is stable and provides high yields hence economically viable
Pests and diseases are easier to get rid of
Ease of harvesting
It is better for consumption
Commercial viability of
Nutrient rich water
Air Stone
Water Pump
Plants samplings
In static solution culture, plants are grown in containers of nutrient solution, such as glass jars, plastic buckets, tubs, or tanks. The solution is usually gently aerated but may be un-aerated. A hole is cut in the lid of the reservoir for each plant. There can be one to many plants per reservoir. A home made system can be constructed from plastic food containers or glass canning jars with aeration provided by an aquarium pump, aquarium airline tubing and aquarium valves.
In continuous-flow solution culture, the nutrient solution constantly flows past the roots. It is much easier to automate than the static solution culture because sampling and adjustments to the temperature and nutrient concentrations can be made in a large storage tank together. A popular variation is the nutrient film technique or NFT, whereby a very shallow stream of water containing all the dissolved nutrients is recirculated past the bare roots of plants in a watertight thick root mat, which develops in the bottom of the channel. Subsequent to this, an abundant supply of oxygen is provided to the roots of the plants.
Recycled (Recirculating)
Nutrient
Reservoir
Waste
Tank
“Run-to-waste” describes those systems where the excess nutrient or “run-off” is not re-circulated. Conventional ‘soil culture’ is a type of run-to-waste system. Media with a high water holding capacity are used (e.g. soil, coconut fibre, Rockwool). Feeds are small and infrequent. The ‘run-off’ is either drained directly onto the ground or is collected. Collecting the run-off allows feed volume and frequency to be calculated more accurately. This helps prevent under-dosing or over-dosing.
Water Flow
In a re-circulating or recycled system the water is pumped from a main reservoir to the plant root system , the excess water and nutrients are then returned to the reservoir. Trace elements are topped up as used and regularly dumped and refreshed to keep the system stable . They are more cost effective in both water and nutrients. Because of their nature and the methodology used to top up the nutrients, re-circulating systems tend to require more regular checking and correcting of pH , and EC levels which adds that little bit more maintenance time spent in the grow room

Growstones, made from glass waste, have both more air and water retention space than perlite and peat. This aggregate holds more water than parboiled rice hulls.
Coir
Perlite
Coco Peat, also known as coir or coco, is the leftover material after the fibres have been removed from the outermost shell (bolster) of the coconut. Coir is a 100% natural grow and flowering medium. Coconut Coir is colonized with Trichoderma Fungi, which protects roots and stimulates root growth.
Perlite is a volcanic rock that has been superheated into very lightweight expanded glass pebbles. It is used loose or in plastic sleeves immersed in the water. It is also used in potting soil mixes to decrease soil density.
Sand
Gravel
Sand is cheap and easily available. However, it is heavy, does not hold water very well, and it must be sterilized between use.
The same type that is used in aquariums, though any small gravel can be used, provided it is washed first. Indeed, plants growing in a typical traditional gravel filter bed, with water circulated using electric powerhead pumps, are in effect being grown using gravel hydroponics. Gravel is inexpensive, easy to keep clean, drains well and will not become waterlogged.
In this, there is a tray above a reservoir of nutrient solution. Either the tray is filled with growing medium (clay granules being the most common) and planted directly or pots of medium stand in the tray. At regular intervals, a simple timer causes a pump to fill the upper tray with nutrient solution, after which the solution drains back down into the reservoir. This keeps the medium regularly flushed with nutrients and air. Once the upper tray fills past the drain stop, it begins recirculating the water until the timer turns the pump off, and the water in the upper tray drains back into the reservoirs.
The hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water. Traditional methods favor the use of plastic buckets and large containers with the plant contained in a net pot suspended from the centre of the lid and the roots suspended in the nutrient solution. The solution is oxygen saturated from an air pump combined with porous stones. With this method, the plants grow much faster because of the high amount of oxygen that the roots receive
Greater control on environment, yields are predictable and budgeting is easier
Tailored macro and micro nutrition for humans, even distribution
Effective recycle resulting reduced water usage

There are two chief merits of the soil-less cultivation of plants. First, hydroponics may potentially produce much higher crop yields. Also, hydroponics can be used in places where in-ground agriculture or gardening are not possible.
Future belief
The future lies in locally grown and sold produce limiting the ‘road miles’.
This method of growing our food is a more sustainable model than those currently practised.
The consumer is becoming increasingly concerned over health issues, environmental issues, even water consumption cost and availability……… these all are drivers for the further development of hydroponic growing techniques.
Global reach
Main countries using hydroponics are Holland, Spain, Australia, USA, Canada, NZ, Italy, Canada, Mexico, China. Even our neighbor Pakistan has adopted Hydroponics cultivation with major government support.
Main crops are Cucumbers, Tomato, Lettuce, Strawberry, Herbs, Capsicums, cut flowers etc. but not limited to these alone.
Resource universe of commercial hydroponic agriculture
Nutrient recipe
Numerous 'recipes' for hydroponic solutions are available. Many use different combinations of chemicals to reach similar total final compositions. Commonly used chemicals for the macronutrients include potassium nitrate, calcium nitrate, potassium phosphate, and magnesium sulfate. Various micronutrients are typically added to hydroponic solutions to supply essential elements; among them are Fe (iron), Mn (manganese), Cu (copper), Zn (zinc), B (boron), Cl (chlorine), and Ni (nickel).
Pre-mixed concentrated nutrient solutions are generally purchased from commercial nutrient manufacturers by hydroponic hobbyists and small commercial growers, several tools exists to help anyone prepare their own solutions without extensive knowledge about chemistry.

Opportunities
Indian hydroponic practitioners needs to overcome
Body of knowledge
We need to convene an association in India for Commercial Hydroponic Growers even before we start the first commercial system in our country.
We have a student of Simplified Hydroponics already having an association called Indian Hydroponics Pioneers Association.
Formulate industry standards
We need to use foreign Hydroponic experts to start with. This is an absolute must as there are no resource people in India at this time. Industry standards will be established as time goes by and more Indians adopt this kind of cultivation.
Marketing of hydroponic produce
It is marketed more on the quality and consistency, rather than the method of production.
More and more Indians are demanding high quality, pesticide free, fresh produce. Money not the criterion.
People are aware of dangers of pesticides, global warming and its ill effects. Media plays an important role.
Consistency, quality and yields possible only by modern techniques of cultivation.
