What Is The Hydroponics

What Is The Hydroponics? – Definition and Techniques

Before explaining the hydroponics, we have to know how natural plants grow in normal farming. 

Natural plant seeds are put in the soil and start these seeds absorb water and nutrients from the surrounding soil. Why? To generate energy to form its biosystems and start growing up.

When the shoots start to appear on the soil, it will need more and more energy to continue growing.

So it uses a method called photosynthesis, in which they use sunlight and a chemical inside their leaves to convert carbon dioxide and water into glucose (a type of sugar) and oxygen.

So how can we define hydroponics?

Hydroponics is a type of growing plant mainly for food, materials, comfort, and beauty. Hydroponics is a method of growing plants, usually crops, without soil, by using mineral nutrient solutions in an aqueous solvent.

No!!! That Is Stupid?

Not really. We got used to seeing the plant and soil together, that growan and green colors, we love it.

What is the hydroponic gardening? What are the techniques used in?

What does that mean?

You will not go to your garden (if you have one) and plant some seeds for your favorite plant. Instead of that, you can use the hydroponic method to grow plants inside your house, especially if you don’t have a garden.

The nutrients used in hydroponic systems can come from many different sources, including (but not limited to) fish excrement, duck manure, purchased chemical fertilizers, or artificial nutrient solutions.

What can I grow in this type of farming?

Plants commonly grown hydroponically, on inert media, include tomatoes, peppers, cucumbers, strawberries, lettuces, and model plants.

How did hydroponics start?

The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum or ‘A Natural History’ by Francis Bacon,

Water culture became a popular research technique after that. In 1699 John Woodward published his water culture experiments with spearmint.

He found that plants in less-pure water sources grew better than plants in distilled water. 

It quickly became a standard research and teaching technique and is still widely used. Solution culture is now considered a type of hydroponics where there is an inert medium.

Around the 1930s plant scientists investigated diseases of certain plants, and thereby, observed symptoms related to existing soil conditions. 

In this context, water culture experiments were undertaken with the hope of delivering similar symptoms under controlled conditions.

Hydroponics is derived from neologism υδρωπονικά (derived from Greek ύδωρ=water and πονέω=cultivate).

One of the earliest successes of hydroponics occurred on Wake Island, a rocky atoll in the Pacific Ocean used as a refueling stop for Pan American Airlines. 

Hydroponics was used there in the 1930s to grow vegetables for the passengers. 

Hydroponics was a necessity on Wake Island because there was no soil, and it was prohibitively expensive to airlift in fresh vegetables.

In recent decades, NASA has done extensive hydroponic research for its Controlled Ecological Life Support System (CELSS). 

Hydroponics research mimicking a Martian environment uses LED lighting to grow in a different color spectrum with much less heat.

Ray Wheeler, a plant physiologist at Kennedy Space Center’s Space Life Science Lab, believes that hydroponics will create advances within space travel, as a bioregenerative life support system.

In 2007, Eurofresh Farms in Willcox, Arizona, sold more than 200 million pounds of hydroponically grown tomatoes.

As of 2017, Canada had hundreds of acres of large-scale commercial hydroponic greenhouses, producing tomatoes, peppers, and cucumbers.

What are the techniques of hydroponics?

There are a lot of ways to grow plants hydroponically, each one uses specific nutrients. 


  • Static solution culture technique
  • Continuous-flow solution culture technique
  • Aeroponics technique
  • Fogponics technique
  • Passive sub-irrigation technique
  • Ebb and flow (flood and drain) sub-irrigation technique
  • Run-to-waste technique
  • Deepwater culture technique 
  • Rotary technique

What are the growing support materials?

We have said that hydroponic method do not use soil for growing, so what materials plant can use for that?

  • Expanded clay aggregate
  • Growstones
  • Coconut Coir
  • Rice husks
  • Perlite
  • Vermiculite
  • Pumice
  • Sand
  • Gravel
  • Wood fibre
  • Sheep wool
  • Rock wool
  • Brick shards
  • Polystyrene packing peanuts

What can we use for hydroponic farming as Nutrient solutions?

  • Mixing solutions
  • Additives
  • Organic hydroponic solutions
  • Tools
  • Inorganic hydroponic solutions

The Benefits Of Hydroponic Gardening

As we know gardening in a hydroponic system is a modern method of future farming. According to many studies and statistics, hydroponics is experiencing remarkable growth around the world.

Due to technological advancements within the industry and numerous economic factors, the global hydroponics market is forecast to grow from US$226.45 million in 2016 to US$724.87 million by 2023.

But what the reason for this growth?

Of course the farming needs more improvements to meet huge requirments of growing populations.

Because of lack of arable lands, it had to invent new ways in order to increase returns of growing plants.

The hydroponic farming solves many of concerns related to human health like using chemicals and toxic materials.

So what are the benefits of hydroponic systems?

What Is The Hydroponics

The farmers are more able to manage nutrients to make sure plants are getting the exact nutrients they need. The systems in hydroponics are closed and controlled.

This ability in growing indoors plants allows us to control temperatures and lighting schedules to improve plant production.

These benefits include:

  1. Up to 90% more efficient use of water.
  2. Many crops can be produced twice as fast in a well-managed hydroponic system.
  3. No chemical weed or pest control products are needed when operating a hydroponic system.
  4. Indoor farming in a climate-controlled environment means farms can exist in places where weather and soil conditions are not favorable for traditional food production.
  5. Family Experience – A great way to spend quality family time together.
  6. Relaxing – All gardeners tell you the same thing, it is a relaxing hobby.
  7. Enjoyment – Your success is all but assured with hydroponics.
  8. Better Results – Hydroponics produces better tasting, more nutritional results.
  9. Affordable – Get started on a very low budget, and save on any size of the project.

Produces More Healthier Plants

In hydroponic farming, plants grow healthier than in soil.

For one thing, soil-borne diseases aren’t an issue in hydroponics because there is no soil for those diseases to fester and spread in.

Plus, plants don’t have to spread their roots out in search of nutrients so they get to spend more energy on growing.

Has Bigger Yields

Because more plants can be grown in small spaces with hydroponic farming than soil farming, hydroponic systems typically yield more per square foot.

Additionally, plants are healthier and grow faster, generating more produce faster.

Indoor conditions also allow for year-round growing, regardless of weather or season, so plants’ that continue to produce after the initial harvest can be harvested more times.

There Is No Soil Erosion

Field agricultural practices have eroded half of the soil on Earth in the last 150 years, decreasing the availability of arable land.

Hydroponic systems don’t use soil.

No soil means no soil erosion. It’s that simple.

There Are No Weeds

Hydroponic systems are not habitable for the seeds of weeds.

Weeds need the same things as other plants to sprout, but seeds aren’t typically sowed in hydroponic systems.

That way the system can be tailored to the growing phase rather than germination.

Since the seeds can’t start germinating, weeds won’t take root and steal your crops’ precious nutrients.

Now that you know the benefits of hydroponic farming, it’s time to get started.

Nutrient Control

Hydroponic systems feed plants a nutrient solution mixed with water, giving the farmer better control over what nutrients their crops soak up.

Cultivar grown in soil may need the help of fertilizers to survive. But in hydroponics, the plants are already receiving all the help they need and the right amount of it.


Due to technological advancements within the industry and numerous economic factors, the global hydroponics market is forecast to grow from US$226.45 million in 2016 to US$724.87 million by 2023.
