Ok, I checked my tap waters ppm and they are 150-180 range can I use it for growing?
Also for storage for the ppm test what does one do I did not find anything like I did for my pH tester. My pH tester says to place a few drops of pH in the cap and seal it. I could not find anything for the ppm tester.
Thanks
