Ensuring your pH is correct allows for your crop to uptake nutrients efficiently. Without monitoring your pH and EC levels, you’re essentially growing blind. pH and EC measurement are basic tools on the belt of a hydroponic farmer.
pH is a measurement of the acidity or alkalinity of an aqueous solution and should always be monitored in hydroponic/aquaponic cultivations 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.
Handy, convenient and accurate for home or commercial growers!
