Thanks for the explanation VG.Run off in LOS will give you skewed readings. Minerals, organics etc. will migrate their way into the lower root zone and out the bottom every time you water. This could make you think your pH is much lower than it actually is. It would be alarming to try to read PPM. You could potentially get a really high number that would put an inexperienced grower into a panic.
Fox farms and other craft soils are the same way.
Soil pH can vary quite a bit between the top and bottom of the pot ,so when a slurry is preformed samples are taken from a few locations within the middle of the root zone. Tested independently they will give you a good idea of your over all soil pH.
So to me it seems like an extra step. One that won't give you a clear picture of what is really happening and has potential to confuse.
I run a different growing medium and I am always looking to learn. My 5 gallon buckets have holes drilled all around the sides and bottom giving me ample access to my entire root zone. The soil ph monitoring I was doing was in conjunction with moisture content analysis. All this was tied into the rezination process wherein we apply abiotic stress (drought) at or near the end of bloom.
I am way too bizzy with all this, and might have a little more free time if I would stop with the extra work I pile on. I should have gotten a hint when Stone told me his pen was out of cal. LOL
But what would I do with all this free time...
