If there is one stubborn challenge hydroponics gardeners face when it comes to nurturing plants, then it must be the need to deal with an overheating reservoir. Plants need optimal temperatures to grow healthy but when the temperatures are extreme, the plants’ growth is affected.

What is a water chiller?

A water chiller or a hydroponics water chiller is a device installed in the garden, to regulate the temperature in the container it is installed in. This way, the plants get a nutritious solution that’s at an ideal temperature for their growth. Usually, a water chiller comes with a thermostat for measuring and controlling the temperature.

Types of hydroponics water chillers

Here are the three types of hydroponics water chillers.

 

  • Drop-in water chillers

 

These are water chillers that come with a system that filters the air which enters the water. Usually, drop-in water chillers are set directly into the water filters. These types of water chillers are ideal for deep water culture hydroponics. They are easy to fix and they don’t consume much space.

 

  • Thermoelectric water chillers

 

These types of water chillers are suitable for smaller aquarium and hydroponics gardening. They are silent when working, and are the most cost-efficient water chillers of all.

 

  • In-line water chillers

 

These types of hydroponics water chillers use in-line filters to regulate the water temperature. You will need a plumber to fix these water chillers if you are not a good plumber. They are also ideal for a large water system and NFT hydroponic system.

What is Hydroponics?

We might have used this term several times and you are left wondering what the heck “hydroponics” is.

Generally, hydroponics is the process of growing plants in a container with a mixed solution of water and nutrients. The plants are grown in a soilless environment.

Well, this method of gardening does not occupy too much space and nurtures plants fast. 

Note that before you enter into this type of gardening, you must familiarize yourself with the challenges you can expect encounter, and how to overcome them. It’s an involving method that’s also costly.

Why use water chillers for hydroponics?

Usually, water chillers are designed for fish aquariums. However, currently, water chillers are becoming popular machines for use in hydroponics gardens. In hydroponics gardening, plants are planted in the water.

To keep your plant healthy and happier, you need to keep the temperature regulated constantly as too high temperatures decrease the oxygen needs by the plant’s roots.

Benefits of using a water chiller for hydroponics

The use of water chillers for hydroponics seems to be hitting the ceiling currently and this is because of the benefits these containers have on your hydroponics garden.

Some of the benefits of using water chillers for hydroponics include:

 

  • Sufficient oxygen levels

 

Usually, with hydroponics gardening, plants are grown in soilless gardens. When the temperatures of the water go up, the plant suffers. Water chillers help to keep the plant constantly supplied with dissolved oxygen because of the cooler temperatures maintained by the water chillers.

 

  • Efficiency 

 

Water chillers conserve water and energy. Water is recycled as many times as possible hence you don’t need to drain warm water from the hydroponics or aquarium system. Moreover, most of the latest water chillers are energy-efficient.

 

  • Protects the plants against diseases 

 

Generally, pathogens and disease-causing organisms breed in warm conditions. Therefore, in areas with hotter temperatures, plants can be attacked easily by diseases. That’s where water chillers become helpful. These machines help to ensure fresh air circulates freely around the plants hence keeping diseases and other micro-organisms at bay.

Final Thoughts

Using water chillers for hydroponics is the only effective way to keep the temperature in your hydroponics system controlled and monitored at all times.

Given the plethora of options available on the market today making the right choice can be a hard task.

We hope this article helped you in your search for the ideal water chiller for your hydroponics garden.
