Definition - What does Nutrient Chiller mean?
A nutrient chiller is a cooling device used in hydroponics to maintain a proper temperature of the nutrient solution in a reservoir or tank.
Nutrient chillers are sometimes referred to as water chillers and can sometimes be combined with a nutrient heater, leading to convenient, all-in-one heating and cooling of a hydroponics system. They are especially useful in greenhouses as well as in climates that have highly fluctuating weather conditions and climates.
MaximumYield explains Nutrient Chiller
In hydroponics, warm water contains less dissolved oxygen than cooler water and can lead to poor root growth or increase the chances of disease. For this reason, a nutrient chiller is used to cool the nutrient solution during warmer periods.
The optimal growing temperature of the nutrient solution is 18-20 degrees Celsius or 68 to 72 degrees Fahrenheit. The nutrient chiller consistently maintains this temperature.
A nutrient chiller used in hydroponic set-ups will ensure that your plants remain healthy and receive the amount of dissolved oxygen they require for good root growth.
The nutrient chiller is essentially a mini refrigerator. However, it does produce some residual heat. Therefore, it should be placed outside of the primary growing area if possible.
The size of the nutrient chiller required depends on the volume of solution that is being cooled. The bigger the chiller, the less time required in order to cool the solution.
