Q: What is the suggested pH range for my hydroponic system and soil plants?
A: Hydroponic and soil gardens differ in the fact they both need different pH ranges for nutrients to be made available for plant absorption. Maintain a pH between 5.0 and 6.5 for hydroponic gardens and 6.0 to 7.0 for soil applications.
Q: My pH meter doesn't hold calibration. How often should I recalibrate it?
A: pH meters do need to be calibrated by the user every day since the membrane does change and is affected by the temperature as well. If pH values are very critical then it will need to be recalibrated several times a day, or before each sample test (depending on how critical the value is). Uncontaminated calibration solution is very important as well. For each calibration, pour some solution in a separate container. Keep out of sunlight and away from heat.
