Water heaters will stop your water from getting too cold during the winter months while chillers will stop the water from getting too hot during summer and heat waves. The temperature of a hydroponic solution is extremely important for the availability of nutrients within the solution as when the temperature gets too cold, plants won't be able to uptake nutrients. When the temperature of the nutrient solution rises too high, diseases such as pythium can take hold and if left untreated it could ruin an entire crop.

Water Heaters

Water heaters allow you to easily maintain a lukewarm nutrient solution in cold conditions. If water temperatures get too low, the plant can go into shock from stress which could stunt growth. Cold nutrient solutions also make it hard for the plant to uptake nutrients from the solution so with a tank that sustains a temperature that's too cold it will start to show deficiencies, which if not corrected will be detrimental to yields.


Optimal Nutrient solution temperature should be between 18°C and 20°C. If temperatures rise more than this for a significant amount of time, the risk of negative root diseases such as pythium and fusarium dramatically increases.


Use a nutrient chiller during summer and a nutrient heater during winter to maintain the perfect temperatures in your nutrient solution to facilitate plant growth.
