I bought a ph meters similar to this
Rapitest Soil pH Meter Model 1840 - 716750
it only cost like $20. when i stick it in pure vinegar, it maybe only drops to about a ph of 6. It doesnt seem like it is suppose to test liquids, though.
im not interested in being accurate to the tenths place etc., but i dont want to keep adding pH down to try and lower the pH when its just the meter isnt showing the correct pH, for example.
my question is does anyone use these cheaper meters? are they decent for soil? should i just buy a kit to test the pH of my liquids? i'm on a budget for my first grow and i dont want to spend any more money unless it will help my results a lot, at this point.
THANKS!
