do inexpensive PH meters really work ?
PH METERS ?
That's a very good question. I bought a cheapo one at the local nursery that said my garden soil is 5.0 ???
I bought a "4 in 1" meter (pH, moisture, light, and fertility). Even when I have just watered the meter says "dry", even if I have just fertilized it says "needs fertilizer". Hard to trust the pH reading after that... mine has been saying the potted brugs are 6.0 & 6.5, but the numbers do reflect change if I add a bit of lime.
I use the myron l agrimeter 6/ph and it seem to work very well. It has the ability to test ph and ec. It seems to be very accurate. I did lots of research and spoke with a lot of people before I purchased it.

Jeremiah, did you order it online or get it at a store?
edited to say,
checking online sources, it seems to be in the $200 range...

wow....I'm thinking more in the $20-$50 range.
I'm thinking it was around $450 with the soil test kit.

Holey moley Jeremiah...thats a bit beyond my budget but I bet it works good !
I have an inexpensive ph meter and it seems to be pretty accurate. it's by Bond. it measures moisture, light and PH
I got mine from Wal-mart and it seems to work pretty well. I think I paid around $8 for it.
Yes...that is the type of thing I was considering...especially in regards to PH as I like to mix my own soil...I wonder if the $20 ones work any better than the $8 and have any of you had your soil tested another way to check the degree of accuracy of the meters.
well.. I believe that household vinegar is about 4.. amonia about 12 and distilled water between 5.6 and 7. SO you can play and see what you get
Good answer, good answer, Jazz.
