    Do not guess. Know exactly what your pH, EC and total dissolved solid (TSD) levels are in your hydro reservoir or your media. You may have all of the nutrients that your crops need, but they are unavailable to them because your pH is too high or too low. By using one of these Hanna meters, you will be able to monitor and adjust your pH and nutrient levels in real time before any damage can be done.
