How Does Hydroponics Work

How does hydroponics work? That’s going to be one of the first questions to ask if you want to learn about hydroponics. I will give you different cases but to gain a solid understanding of hydroponics, you need to start first with the basics of hydroponics, the history of hydroponics, and hydroponic plants.
First of all, “hydroponics” comes from the Greek for “hydro” meaning water, and “ponos” which means labor or work. Basically, what it boils down to is that the water does all the “work” by taking place of the soil. With hydroponics, you can grow any kind of plant including tomatoes or orchids.

How Does Hydroponics Work

If you are a gardener, you know that the key to having a successful garden is to make sure all the needs of your plants are met so that they can have optimum growth. If one thing is missing then the plant does not grow as well or produce as it should. When learning how does hydroponics work, you will gain a thorough understanding of the entire process.

Water & Nutrients

One of the needs plants have is a proper blend of nutrients. When plants grow in soil, the root system grows and reaches out to collect what the plant needs and delivers it to the rest of the plant. Water is critical in this process because it breaks down the nutrients in the soil, such as calcium for instance so that the root system can absorb the minerals and use them to bring on plant growth.


The same thing happens with the tomato plant that you are growing with hydroponics except that your plant is fed specially fortified water and grown either in the water or in a soilless medium such as perlite or peat moss and the nutritional needs of your tomato are already in the water. Everything your tomato plant needs is in the water used in hydroponics the proper pH, minerals and food perfectly balanced for your tomato plant.


To make sure the plants get everything they need and in a consistent manner, you may want to use a timer, bubblers, and pumps to make sure that the plants do not dry out because the growth medium does not conserve moisture.

Growing Energy

The reason hydroponics is so successful is that your tomato plant does not have to work as hard as its soil-growing cousins do. As a result, your tomato grows faster and larger because the energy that usually goes into establishing a root system to feed the whole plant is focused on the rest of the plant. Your tomato is freer to grow upwards and it will concentrate more on producing fruit.
In addition, if you choose to grow your tomato in a controlled environment, as many in hydroponics do, it will get everything it needs to grow. It gets the right amount of light, the optimal temperature and is free from insects and other pests that stress out and damage the plant.
Whether you say how does hydroponics work or how to do hydroponics work, the important thing is that you learn the basics before you get started.

About Hydroponics

If you’ve ever heard someone mention hydroponics, you’ve probably wondered, what is hydroponics and how does it work? Hydroponics, which means, “working water”, is a method of growing food in water alone without using any soil. This may seem impossible, but researchers have found that plants are very capable of growing in materials other than soil, as long the nutrients they need are in that material.

History of Hydroponics

You might be surprised to learn about the history of hydroponics. Historians have found that ancient peoples may have used hydroponics as a growing technique. Some believe the Aztecs created floating gardens, and hieroglyphics in Egyptian ruins describe plants growing in water. However, up until the mid-1900s, most of the population still had not heard of this technique and often asked what is hydroponics? Dr. William F. Gericke, who successfully produced a large number of vegetables, flowers, and fruits using hydroponic gardening, invented the word “hydroponics”. His 25-foot high tomato plants attracted the attention of the military, which then used hydroponics to grow fresh produce for soldiers during World War II.

 Growing Without Soil

That’s interesting, you say, but just what is hydroponics farming; how can plants grow without soil? All plants have a root system, which they use to absorb nutrients. It doesn’t really matter to the plant what kind of medium how those nutrients are delivered. They can be in sand, gravel or vermiculite, to name a few. The one thing all plants must have, however, is water.

Hydroponic methods of growing plants simply use water, or water mixed with one of these other mediums. These mediums simply provide a solid way of supporting the roots, versus water only, which requires the plants to be supported in some way above the water, allowing their roots to be submerged.

If you are thinking about growing your own hydroponic plants, there are some basic supply needs. Decide whether you wish to use purely a water-based hydroponic method or use a solid medium such as gravel, etc. Beginners may want to start small, using something as simple as a dish or tray. There are also preassembled hydroponic kits available on the internet for those who want an easy way to get started.

Plant nutrients come in several forms. You can purchase some in a pre-mixed form or a condensed mixture and needs to be diluted before being used. It’s important to remember that nutrients will need to be refreshed periodically, depending on the number of plants and the size of your garden.

Since water is the number one need of all plants, testing yours via a water analysis is a good idea. If using artificial lights, be sure to select ones offering a full spectrum to simulate natural sunlight. Spend some time researching the type of plants you wish to grow and find out their specific lighting and nutrient needs. Soon you’ll be the expert who can answer the question many people have which is…what is hydroponics?
