hey gotmud!
i have one of those ph testers your talking about, i think.
did it come with little white pieces of fabric for rubbing the shaft with?
well if so its the same style as mine and i have no clue how accurate it is, i never really used it as a diagnostic tool just more for shits and giggles. from what i understand ph is less of a problem in soil as opposed to hydro and thats why i never really worried about it. i also have one of those water ph tester kits with tubes and drops and color matching but i never used it either.....
so heres some questions that could help us both!..
if i were to collect some runoff water from my planters after watering and checked the ph with the water tester would that give me an accurate measurement of the soil ph? and will ph up or down effect the soil ph or the water ph...are they directly related?
