Hydroponic Water Heaters & Chillers

Water heaters and chillers are important in hydroponics to maintain the temperature of the plants root zone. The exact temperature depends on the variety of plants you are growing, but aim to keep water in your hydroponics system between 18-22°C. If the temperature is too cool (below 18°C) it will slow and stunt plant growth. If the nutrient solution is too hot (above 22°C) the amount of dissolved oxygen in the solution decreases and it also becomes a breading ground for bacteria.
