hiya i got one of those digital ph meters but the instructions are like double dutch and don't really help me much. what are the buffers for and how do you use them, ie i got two bottles with the meter, one at 6.98 or something and the other one in the 4.0 region, what do you do with these, do you immerse the thing in the solution or do you mix it with water first and if so how much? the instructions mention that you use them to calibrate the meter, does that mean so that you get an accurate reading, but what one do you use? any info would be appreciated, i had a dropper test kit but the colours are quite similar and found it hard to tell the exact ph, and i need to save my plants due to a ph problem so need help asap!! thanks anyone!
