Importance of accurate pH readings
Think of nutrients like a lock and pH is the key. A key factor that affects nutrient uptake for plants is whether your solution is acidic or alkaline which is measured with pH.
Make use of the Probe Care Kit to ensure that your BlueLab tools are well-maintained and reading accurately.
Electrodes need to be calibrated on a regular basis due to the fact that as an electrode ages, its glass changes resistance. This resistance change alters the electrode potential, and therefor, the accuracy of the reading
The following solution is advised for long term probe maintenance: Probe KCL Storage Solution.
