I am one of the ones who just blow through the amazon cheapos. Never calibrated it as long as im roughly within a few points my organics work really well to keep my soil PH right. Having organics in your mix is clutch!Ive never even heard of the last three. I’m gonna have to do some research.
You guys recommend a quality inexpensive ph reader? I have the vivosun and it’s absolute shit
