Topic: Ph Meters. Do they work?

Have seen this on a well know auction site.

Price seems reasonable, but do they work?

Not sure how well they work, but I've got the 2 pronged version, bought it from Wilkinsons last year. Seem to remember it being about £7, but not sure about that either.
What I will say is that the reading does vary from soil to soil, so it is measuring something  ???. The 2 prong one also does light and moisture measurements though.

If you're gonna buy one, I'd get to Wilkos.  :)

I have one I rarely use.

Don't know if they are accurate but they will certainly tell you if your soil is too far one way or the other. i.e. acidic/alkaline

Handy if you are considering adding lime and you don't know what your soil is like.

Clean them with a brillo pad/pan scourer or similar after every test to remove all traces of previous test.

I prefer the  liquid method - reckon it's more critical.

But yes, the probes do read changes.

Thanks all.
I recon a trip to the local Wilco's is on the cards.

Found mine outside today..the bl00dy thing's broken!

Oh well, never really used it anyway.

You can see if it's too light/dark.

And if you don't know whether you need to water, you need help.   :P

Best get the liquid ph thingy out next time eh?   ;)
