What is a hydroponic system?

A hydroponics system is simply a portable garden where you can grow your plants.

Basically, the system uses a nutrient rich solution instead of soil. Most people think that soil is the only way to grow plants; in fact there are other more efficient ways.

The hydroponic system allows you to use insert media such as Rockwool, perlite, clay pellets, vermiculite or peat moss to support the root system.

One of the key advantages of a hydroponic system is that you only deal with a controlled environment.

This means you can adjust the system depending on what you intend to grow.

Besides, it helps keep the nutrients in direct contact with the plant roots thus keeping your plant nourished throughout the season.

How hydroponic systems work

There are several hydroponic systems available for use. Some of the systems include;

Wick system

The wick is a simple hydroponic system that uses a passive system; basically, it does not have moving parts.

The system uses a wick to draw the nutrient solution from the reservoir into the growing media.

The main growing media used include coconut fibre, perlite, vermiculite or Pro-mix.

Unfortunately, this type is not suitable when growing plants that require a lot of water since the wick cannot supply the nutrient solution as required.

Ebb& Flow

Also known as the flood & drain system, it functions by flooding the growing tray with the nutrient solution for a short time.

It later drains the nutrient solution to the reservoir. This process is done with the help of a submerged pump linked to a timer.

Basically, the timer is set to turn on the submerged pump allowing the nutrient solution into your grow tray.

After the timer shuts the pump, the nutrient solution pours back to the reservoir.

The Ebb & Flow system can work well with many growing media. You can choose to use Granular Rockwool, gravel, or grow rocks.

Drip systems

This is one of the common types of hydroponic systems that most developers use.

The best part?

It is easy to operate since you only need to set a timer to control a submersed pump.

The timer controls the pump allowing the drip line to supply the nutrient solution onto your plants’ base.

Any unused nutrient solution collects back into the base for reuse.

On the other hand, if you use the non-recovery model, it does not collect unused nutrient solution.

Water culture

It has been rated as the simplest in the active hydroponics category.

Developers opted to use Styrofoam as the platform of the plants.

Styrofoam floats on your nutrient solution.

The system works by blowing air to an air stone located in the platform; the air bubbles the nutrient solution thus supplying oxygen to the plant roots.

This type has been recommended for growing leaf lettuce.

Water culture only favors water-loving plants; it does not work well with large plants.


It is considered as the most advanced and sophisticated hydroponic system.

Their roots hang in the area and automatically get misted with the solution.

Most noteworthy, the misting process is done every few minutes since the roots are directly exposed to the air.

Any interruption with the misting cycle might result to the plant roots drying.

The system uses a timer that runs the pump for around 5 seconds every minute.

Nutrient Film Technique (N.F.T.)

This system suits beginners since their systems are set to supply the plant roots with nutrients without the need of a timer.

The nutrition solution is simply directed to the grow tray and flows over the roots until it is tapped back to the reservoir.

Similar to the Aeroponic system, the only growing media used here is air.

The best part?

You do not have to replace your growing media after each crop hence saving you money and time.
