Many people use hydroponics to grow plants that use nutrient-rich solutions in water, so there’s no use of soil. Instead, some materials support plant roots, such as peat moss, rock wool, perlite, and clay pellets.

Hydroponics has existed in various forms for thousands of years, from Babylonian hanging gardens to ancient Mexican Chinampas.

Only in the past 70-80 years have we understood the science behind this technique. While we have practiced hydroponics in various forms for centuries, some places have sometimes been more developed than others. For example, people use ac infinity to ventilate their growing space. 

In this article, you’ll learn all you need to know about hydroponic systems. We will aim to answer these questions that include:

What is hydroponics?

How do you set up your hydroponic systems?

What systems do people use in hydroponics?

What are the advantages of hydroponics?

What is hydroponics?

Hydroponics refers to any growing of terrestrial plants that delivers nutrients directly to the roots rather than having the roots seek them out by digging in a soil body. 

We derive the word hydroponics from the Greek word hydros, which means water, and pon means work. The plant’s roots receive nutrients from water-based nutrient solutions.

How do you set up your hydroponic system?

Depending on what your tastes are, your hydroponic system can be simple or very complex. It is possible to set up several approaches that require little effort and set up some that require a significant investment.

The three elements of hydroponic design include: 

1. Growing containers

2. Sump tank

3. Pump

Systems used in hydroponics

Selecting a hydroponic system involves choosing from six different types. They all revolve around the use of water and nutrients. Each design addresses the core elements but in slightly different ways.

1. Water culture

Water culture is a simple and inexpensive system. We place plants in a basket above reservoirs filled with nutrient solutions. After hanging in the solution for a while, the roots descend entirely into the soil. They will need regular aeration leading to faster growth to prevent suffocation because of constant submersion. 

1. Nutrient Film Technique (NFT)

The system comprises a shallow, downward-sloping stream of nutrient solution. This stream contains roots that absorb nutrients from its steady flow. Growing lettuce, herbs, and baby greens in this system are excellent for plants with a short growth cycle.

1. Aeroponic

By creating an aeroponics system, we expose roots to as much oxygen as possible. Growing chambers without growing medium allow roots to hang upside down in midair, exposing their entire root system. As the roots grow, we mist them periodically with aeroponics misters within this section. It has proven successful commercially propagating seed potatoes, growing tomato plants, growing leaf crops, and growing microgreens using aeroponics techniques.

1. Ebb and Flow

A water pump runs on a timer in Ebb and Flow, also known as Flood and Drain. Water and nutrients flood and then drain the root system. The overflow tube allows the excess water to drain through. What’s left is a dry pond with soaking roots and an overflow tube to drain water away. 

1. Drip

We use perlite or gravel as a drip system for supplying the roots with nutrients. We then pump water and nutrients into them via tubes from a reservoir. Soaking the growing medium and roots makes the solution drip back into the container and the pool. 

1. Wicking

Plants grow in wicking media, such as vermiculite or perlite. You can find them in a container next to the water and nutrient reservoir. To connect a wicking medium to a solution, we use wicking ropes or strips of felt.

What are the advantages of hydroponics?

Hydroponic gardening offers many benefits. Among the most important are:

• Total control over nutrient supply

Because the soil is not a source of minerals or nutrients, it is easy to adjust mineral or nutrient levels based on plant needs.

• Climate or season is not a constraint

Regardless of the weather outside, you can grow hydroponically whenever during the year.

• Better results and higher yields

If we calibrate the hydroponic system and maintain it well, it can effortlessly produce a higher product quality and quantity than a soil-based system.

• Hydroponics offers significant environmental advantages

Not only does hydroponics take up much less space than traditional horticulture, but it also uses much less water. And it allows nutrient solutions to be recycled.

• It is possible to grow all plants hydroponically

You can grow vegetables like potatoes, carrots, onions, etc., that grow on the earth using hydroponics.

Determining Your Best Method

It would be best to have some ground understanding of each system’s strengths and weaknesses, as well as your hydroponic needs, before choosing one of these systems. 

For example, wicks and water culture systems are excellent options for home growers who want an easy setup system. 

Drip systems and NFT systems may be the right choice if you want to grow various plants. Examine each hydroponic system’s pros and cons to pinpoint the best one.

Conclusion

Growing your fruits and vegetables is a fun way to do so from the comfort of your own home using hydroponics. 

The process can become complicated and expensive, but you do not have to make it so if you don’t want to. With all the essential information in this guide, you can better decide for yourself.
