Whether you indulge in indoor gardening, outdoor gardening or hydroponics growing, the
proper balance of the growing environment determines the health of your
plants... Here are some tools to help gain and maintain the proper balance your
plant's environment.
pH: (chemistry) p(otential of) H(ydrogen) TDS: total dissolved solids PPM: parts per million EC: electrical connectivity
The level of conductivity is directly proportional to the amount of salts dissolved in water. The conductivity of your nutrient solution is a measurement of its strength, indicated by the actual amount of salts dissolved.
Experienced growers suggest a pH level between 5.5 and 6.5 for most hydroponically grown plants. A dirty pH probe can skew the readings of your pH meter, resulting in a harmful growing environment.
General Hydroponics Calibration Solutions are specifically formulated for electronic pH meter calibrations and designed for hydroponic solution determinations.
