The temperature of a nutrient solution in a reservoir is one of the most important factors affecting the dissolved oxygen content of the solution. In fact, water’s ability to hold oxygen is directly related to its temperature. As the temperature of the water (or the nutrient solution) gets warmer, the dissolved oxygen potential decreases. As the temperature of the water gets colder, the dissolved oxygen potential increases. Since oxygen is good for the plant’s roots, a grower should try to have the coldest nutrient solution possible, right? Well, not exactly. If the temperature gets too cold, a whole new set of problems are created. Temperatures that are too cold will cause the plant’s growth to slow and eventually stop altogether.
Most indoor horticulturists experience nutrient reservoir temperatures that are too warm. This causes a decreased dissolved oxygen content, which allows anaerobic pathogens to make their home. Pythium, or root rot, is the most common pathogen that plagues the indoor grower with warm nutrient reservoir temperatures. The optimal temperature for a nutrient reservoir is 63 to 72°F. Within this temperature range, the dissolved oxygen content is high and the temperature is warm enough to facilitate nutrient uptake.
