What Does Hydroponics Mean?

To simplify, we can say that hydroponics is the cultivation of plants without soil, that is, without soil and thanks to water, in which suitable nutrients are dissolved to make plants proliferate and in health.

In short, it is the cultivation of plants in water. The etymology of the word hydroponics must be found in the ancient Greek language” hidro “ or water and “ ponos, “which means work; in essence, the word hydroponics identifies precisely the work and the decisive action of the water used - in this case for the development and cultivation of plants, both decorative - fruit and vegetable.

What Is Hydroponic Water Chiller?

hydroponic water chiller The hydroponic water chillers use refrigerant gas to cool the water that passes inside them. They are a little noisy and equipped with a controller to set the desired temperature.

Water chillers ensure that the set temperature is maintained in hydroponic systems or aquariums. They prove to be very effective in cooling the water in the tank.

When Is It Appropriate To Use A Hydroponic Water Chiller?

When it is too hot in summer, it can become a difficult season for hydroponic growers. The higher the temperature, the minor oxygen residue in the nutrient solution. In summer, when the outside or inside temperature reaches 30 ° C and even 40 ° C, you have to start worrying.

With high temperatures and little oxygen available, the roots begin to deteriorate, and in a short time, pathogenic organisms such as fungi and aggressive parasites develop.

We consider that for most plants, the solution’s ideal temperature should oscillate between 15 ° C and 23 C °. So to face the summer heatwave, you can take different ways according to need and economic possibility. Therefore, in this article, we will guide how to choose the best water chiller for hydroponics. Because it is a very economical solution to make your hydroponic system cool in summer.

What Is The Optimal Water Temperature For Growing Plants With Hydroponics?

Of course, this is a primary question knowing that a hydroponic culture’s success depends on good oxygenation of the root mass and that the oxygenation and temperature are two closely related parameters.

Indeed, hydroponics is based on a dynamic flow of water saturated with dissolved oxygen. The higher the temperature, the more oxygen tends to drop in the solution. In summer, when the external - and internal - temperatures rise to 30 and 40 ° C, it can grow to disappear completely. So you have to be ready.

With a high temperature and little oxygen, your roots will start to deteriorate, and diseases will develop. These are primary conditions for insects and pathogenic fungi to multiply on weakened plants which no longer have the strength to defend themselves. If you don’t react quickly enough or don’t know what to do, you can lose plants and even an entire crop.
