Why do hydroponic systems need constant pH and EC monitoring?

In hydroponic growing, nutrients are primarily supplied to plant roots through the nutrient solution. Managing that solution means understanding three key parameters: pH, electrical conductivity (EC) and temperature.

What makes continuous hydroponic nutrient monitoring so challenging?

Continuous hydroponic nutrient monitoring is challenging because a nutrient solution is constantly changing. Plants take up water and nutrients at different rates, pH can rise or fall, EC can become more or less concentrated, and source water and environmental conditions can influence your readings.
