Too hot water is often a problem for aquaculture in a greenhouse, but too cold water is also a major stress factor for plants. Although cold water prevents the formation of algae and contains a lot of oxygen, too cold water has a negative effect on plants. If the water is too cold, the roots of the plant isolate and no longer absorb nutrients from the water. With the BOYU 100W Nutrient heater you can control the temperature of the feed water economically and safely.
