Why PH is Important

You need to know the pH of the water in your system if you want to run your system efficiently. City, borehole and bottled water all have different pH levels so understanding what pH your water is before you add it to the mix will give you a starting value. This can then be measured periodically and the changes will help you better understand what is happening in your system. Once you have added your mixture to the water you may then have to adjust your pH up or down. 

I have not been checking my pH but I plan to start now that I understand the importance. I collect water from Newlands Spring where the water has a pH of about 5.6 which falls between the ideal range for most hydroponic crops of 5.5 and 6.5. Since I am using a A/B mixture correctly I feel comfortable that my pH will be in a suitable range while I order a pH meter.

pH is measured on a scale of 0-14. Pure water has a pH of 7 anything less and the solution is considered acidic, anything above 7 is considered alkaline.
