They also use sensors to monitor pH and electrical conductivity (EC) regularly to determine necessary adjustments for the nutrient solution. Growers may also analyze the microbiome, the genetic material of all the bacteria, fungi, and viruses that live in their water and nutrient solution, to evaluate levels of harmful pathogens, such as Pythium and Phytophthora species that cause root rot.
