PH and EC (electrical conductivity) are two important factors to monitor and control in hydroponic systems, as they significantly impact plant health and nutrient availability. Here's an overview of pH and EC ranges for plants:
pH: pH measures the acidity or alkalinity of a solution. In hydroponics, it is crucial to maintain the pH of the nutrient solution within an optimal range for proper nutrient uptake. The appropriate pH level varies slightly depending on the specific plant species, but a general pH range of 5.5 to 6.5 is commonly recommended for most hydroponic crops. However, certain plants may have more specific pH preferences, so it's important to consider their specific requirements.
EC: EC, or electrical conductivity, is a measure of the nutrient concentration in the solution. It indicates the amount of total dissolved salts (TDS) in the water, including both essential nutrients and any other dissolved substances. EC is measured in units of millisiemens per centimeter (mS/cm) or parts per million (ppm). The EC level of the nutrient solution should be carefully managed to ensure that plants receive an appropriate nutrient concentration.
