I'm looking at using this fertilizer called Herculean Harvest, a liquid calcium phosphate fertilizer, which it recommends to use Olympus Up which is a PH raiser because I assume the Herculean Harvest brings down.
My question is how do you guys test your pH? I am seeing hand held electric meters for like 12$ but I don't know how accurate that can be.
