Correct pH allows your crop to uptake nutrients efficiently. Without monitoring your pH and EC levels, you're essentially growing blind. pH is a measurement of the acidity or alkalinity of an aqueous solution and should always be monitored in hydroponic/aquaponic systems to ensure that your plants are able to uptake nutrients effectively. EC is a measurement of the conductivity of water, or the amount of dissolved mineral nutrients in a solution.
