Water Chiller Hydroponics: The Definitive Buying Guide for Gardeners

Hydroponic Chiller for your Indoor Garden

If you are a fan of hydroponic gardening, you should know that oxygen content in water is extremely critical for the healthy growth of plant roots.

Still curious about it?

There are certain people in our country that ignore this major thing while doing hydroponic gardening which results in higher temperature which results in lesser oxygen content and smaller yields.

On top of that, add the equation of ambient temperature of the surroundings and indoor grow lights.

Here is the result:
A rise in water temperature in an indoor growing environment to a level where the oxygen content in the water is extremely poor.

If the plants are grown in soil, the plant roots are always kept at a steady temperature in the most natural way.

On the other hand, when you use hydroponics the heat from the surrounding heat sources conducts into the water.

We all know that water is a good conductor of heat hence, there is a need to use water chillers hydroponics in order to ensure that your plant roots grow in a healthy manner.

People were using aquarium water chillers earlier to stabilize the water temperatures and provide an optimal environment for aquatic life living in these chillers.

Today, hydroponic gardeners like you are using water chillers as an effective way to keep and check on the reservoir’s temperature.

Wish to learn more about water chiller hydroponics system? It assists in keeping the temperature of the environment stable which ensures that the plants and roots you are growing can take the advantage of oxygen-rich, consistent nutrient temperatures.

It has mostly been observed that a hydroponic chiller costs you a few extra dollars but this is the best option available in the summer months when the outside temperatures rise.

There are two types of water chillers available for hydroponics:

  1. Refrigeration unit
  2. Solid-state thermoelectric cooling system

Let us look at each of these types in detail:


Refrigeration Unit which Helps in Cooling the Roots of the Plants for Healthy Growth

The refrigeration unit works with the help of a water pump which is located inside the small reservoir.

The pump transmits the nutrient solution with the aid of tubing to the unit, where the liquid is refrigerated through cooling coils before being recirculated back into the reservoir.

Solid-state Thermoelectric Cooling System

Solid-state thermoelectric devices use electricity and semiconductors to produce both cooling and heating.

We will tell you the complete truth about water chiller hydroponics. This type of hydroponic chiller is best for small reservoirs.

It has a probe that is thrusted into the small reservoir, leading to chilling of the liquid by getting rid of heat and radiating it away with the aid of a low-speed fan.

Now, that you have gained basic information about water chiller hydroponics it is time to look at the next chapter which discusses the ideal temperature required by plants to grow healthy with the help of a hydroponic chiller.
