just like the title say, I have a really nice kelway Ph meter thats strictly for soil, but I need the pen type that does the liquid Ph to test my runoff and tap water.
reading here last nite some guy had a prob with his soil grow and he was asked for the Ph, ec and tds reading on the run off from his soil?
do I need the ec/tds meter if I'm doing a soil grow? and why would I need it?
what does the ec/tds part test? and what do they stand for?
I think tds is total dissloved solids and it measures the amount of ferts in the water??
I'm about ready to order a liquid PH meter in the next day or so and I don't want to find out next week I should have bought the multi tester that also does the other two.
