PH Meters

PH meters are a necessity in any well run grow room, as they are needed to control the pH level of your nutrient tank.. All the Hydroponic nutrients in the world will do a plant no good if it cannot absorb them easily. A major factor in determining a plant’s ability to uptake Hydroponic nutrients is the relative acidity, or PH (Potential Hydrogen) of the Hydroponic growing medium or Hydroponic solution from which they feed.
