The 10 Best Water Chillers for Hydroponics

A water chiller, also known as a hydroponics water chiller is a gadget fitted in the garden that is used to control the temperature .

 The plants usually acquire a nourishing solution that is at an ideal temperature that supports growth.

Typically, a water chiller has a thermostat for controlling and measuring the temperature.

There are different types of hydroponics water chillers

Below are the three sorts of hydroponics water chillers

 Drop-in water chillers

These types of water chillers contain a system that helps in sifting the air that come into the water.

 The drop-in water chillers are usually fixed directly into the water filters.

These kinds of water chillers are suitable for deep water culture hydroponics. The water chillers do not consume a lot of space and can be easily fixed. 

Thermoelectric water chillers

The thermoelectric water chillers are appropriate for use in smaller hydroponics gardening and aquariums.

They are the greatest cost-efficient water chillers when compared to the rest, and they are also silent when working.

In-line water chillers

The inline hydroponics water chillers make use of in-line filters to control the temperature of the water. 

If you are not a good plumber yourself, then you will need a plumber to fix these water chillers for you.

These types of water chillers are also perfect for NFT hydroponic system and an extensive water system.

Here are the 10 Best Water Chillers for Hydroponics

Since you now understand what a water chiller is and the different varieties of water chillers available in the market.

Here is some explanation on Hydroponics

In general, Hydroponics is the procedure of growing plants in a container that has a diversified solution of nutrients and water.

You usually grow the plants in an environment that does not have soil.

The good thing about the process is that it nurtures plants fast and it does not occupy too much space.

Even though this method of gardening sounds great, make sure you consider the challenges that it may come with.

For example, this method of gardening is expensive and is also very involving.

Reasons as to why you need to use water chillers for Hydroponics

Originally, water chillers are intended to be used in fish aquariums. Nevertheless, water chillers have become common machines for use in hydroponics gardens.

 Remember that in hydroponics gardening of the plants is done in the water.

You will be needed to adjust the temperature since temperatures that are too high regularly will reduce the oxygen needs of the plant’s roots making your plants grow unhealthily. 

You might ask yourself what the perfect water temperature for growing plants with Hydroponics and the reason as to why it is the best is.

Here is more information on that.

There is no water temperature that we can say is recommended when growing plants with Hydroponics. 

The appropriate temperature for the root zones of diverse types of plants differs. The weather also plays a big role when determining the temperature.

 For the tropical and warm-weather plants, they are favoured by higher temperatures than cool-season and temperate zone crops. 

Note that you should attempt to maintain the nutrient solution within a temperature range that stimulates optimal plant health, depending on the varieties of plants you are sprouting.

You may consider a temperature scope of 20-22 °C that is (68-72 °F), which is a great recommendation for hydroponics beginners.

That range of temperature is suitable for those plants that are easy to grow like lettuce and other leafy greens.

 Nonetheless, you will find that the optimal temperature ranges cited by hydroponics experts go up to 24 °C (75 °F) and also a little bit higher to accommodate a greater variety of plants.

Not unless you are gardening outdoors in a climate that is cold or somewhere else where the temperatures go down towards icing.

 The only actual risk of letting your nutrient solution become too low is that it will slow down the plant metabolism process and your plants will have stunted growth.

But if you need to raise the water temperature of your hydroponic system, a candid aquarium heater will be suitable to use.

On the other hand, high water temperatures are way more challenging in Hydroponics.

Very high water temperatures will cause various hostile conditions, that include an increase in the rate of root tissue respiration, heat stress and the production of harmful bacteria, fungi, and other pathogens.

Also, as the temperature of the solution increases, it becomes less able to hold dissolved oxygen, which plant roots need for cell respiration.

The means by which they get the energy to draw in water and nutrients for the entire plant – so higher temperatures cause stress in plants.

The real problem with excess heat in Hydroponics is that things can quickly snowball.

If you’ll pardon the expression, due to a series of negative feedback loops where higher heat causes root tissue to respire at a faster rate.

This causes roots to use up more of the dissolved oxygen in the solution, which is being further depleted of oxygen because of the heat.

This can cause stress to the plants, which weakens them, leaving them more vulnerable to the pathogens that have been multiplying in the high-heat, low-oxygen environment.

When picking the suitable water chiller always consider the size of your reservoir.

 The optimal water temperature at which you need to keep your reservoir and how hot your grow room or garden gets.

Advantages of using a water chiller for Hydroponics

Since the machines have large benefits for your hydroponics garden, they are currently being used by many people.

Here are some of the advantages of using water chillers for Hydroponics.

Water chillers help to maintain the plant frequently supplied with dissolved oxygen because of the cooler temperatures maintained by the water chillers.

Remember that with this type of gardening, there is no soil that the plants can get oxygen from. 

Water chillers are efficient since they conserve energy and water.

Water is reused as most times as possible, so you are not required to drain warm water from the aquarium system or the hydroponics system.

In addition, the latest manufactured water chillers are made in an energy-efficient method. 

The water chiller also protects your plants against diseases since those organisms that cause diseases and pathogens tend to multiply in mostly warm conditions.

Plants can be easily affected by those pathogens and disease-causing organisms in those areas with hotter temperatures.

In those areas with hot temperatures, you will require the help of the water chillers.

The water chillers help to make sure that fresh air circulates spontaneously around the plants, therefore, keeping diseases and other micro-organisms away.

So make sure you purchase a product that will perfectly match your needs.

Do not forget to consider the factors that will show you the effectiveness of the water chiller.
