Budget Soil PH tester recommendations?

[Silver]

I have Blue Lab but all three of these do work. I think they are all made by the same company just different brands? Don't wast money on other cheapos as they do not work!

Nice one @Mañ'O'Green , I'm guessing you tested their accuracy with the bluelab?

I see they have two in the UK ;

I dont understand how they are able to test the PH accurately though when it comes to the root zone. The probe is tiny in length and wont reach far enough down the pot

You want the long probe. Amazon had the long probe in the description probably an error.
