I have color vision deficiency and not able to distinguish several shades of colors.. not color blind, but deficient.
Which is why I was bad at chemistry lab stuff that used colors... it can be a real hassle. So those color based ph tests are not for me.
What is a good ph testing kit for people like me.. something affordable and stays in calibration.
I am using soil with home made potting mix.
