I'll never miss that step againI slurry tested my sunshine 4 was about 6.0 if I remember right. Added some vermiculite and I think I finished at at about 6.1-6.2. been working well for me so far.
IMHO it doesn't matter which soil you use but a slurry test should be done with every soil.
I'd like to know more about this product^@Jimster. Do you know anything about this product.. it's something I bought I'm keeping my garage just in case but I've yet to use itView attachment 992844
Ya i was hoping for some feedback i have some high ph in on of my pots but i'm real hesitant to do anything about it because my girl is sooo sensitive and shes at week 4 right nowI'd like to know more about this product^
I've only had high pH once from too much Dolomite lime but it was hard to lower it

I can't see it taking that long. Atleast not I'm my experience using limestone. Are you talking slurry or pourthrough?You know it can take a week or two for lime to activate on a dry new soil.
Pro mix measures 5.0 straight out of the bale. 6.2 after watered in a week or so.

Some of the lime should be available immediately the rest breaks down over time.
I mean I could add limestone to a tank and within hrs the ph is up in the whole tank.
If your not getting enough runoff it will build up though. By enough I mean enough to remove an adequate amount of dissolved lime.
It should impact it right away. But yes I can see it creating a bit over time
I agree.Also @Aquaman. Lime may turn water ph up immediately but not the soil.
Dolomite is used for fast short term effect and calcitic for long term in pro mix. I think i have that right.
I agree.
Soil doesn't actually have a ph but the soil will influence the water ph by what dissolves into the water. The potential for the influence is dependent on what the soil has that will dissolve in water at whatever rate. If a source does is not dissolve it has no ph value
Yep I agree the elements and availability of the elements in the soil make up the potential for the pH when water is added.Sort of?
All the elements in soil have a much more stable ph than water. Peat is like 4.0ph. Lime is 7.5 to 8ph. Thats what balances out the potting mix.
So would watering with a bottle water like Dasani that has a Ph range of 5.5-5.8 lower PH in soil?I agree.

We need to stop thinking in terms of ph and think in terms of alkalinity and buffering capacity. Ph is a result of acidic and alkaline elements. How much of these elements supplied are not taken into account when reading ph. You can have a ph of 6 with 100ppm worth of elements that when added to soil make no difference over time. But you have a ph of 6 with 10,000 ppm and it's highly likely to affect the soil pH potential pretty quickly.So would watering with a bottle water like Dasani that has a Ph range of 5.5-5.8 lower PH in soil?
Just curious cause my well water is fairly low in PPM but has a ph of about 8.1-8.3 and i see my PH in my potted plant creeping up above 7...and that girl is giving me the middle finger....sooo moody I almost regret cutting clones off of her...thats why i was asking about that fast acting sulfer if anyone was familier with it...thanks for the InfoNo water does not change the ph of anything. Unless it is extremely hard water then its like adding a bit of limestone each time and eventually the ph will go up.
Even ph’ing with ph down doesnt alter the medium until way too much is added over time.
Phing is for nute mixture availability.

well what started my PH paranoia again was watching a poorly made video from Greenhouse seeds on my strain SSH and there ph was more like 5.5-5.8...FAR lower than mine ...GUYS were really good though...made a gorgeous plant...and it's my understanding...could be wrong but the SSH from Mr. nice is the same from Greenhouse....???This is how they buffer soil. By adding enough of each acidic and basic element required to create a stable pH over time. This is why they use lime and peat. Both break down slowly and will have enough of each to lower the impact of additions.
Just for an example this is not accurate info.
You have 100ppm total of acid and basic elements. Say 50ppm acid and 50ppm alkaline. Makes ph 7
No you add 50 more ppm of alkaline that shifts ratio a lot. 100ppm alkalinity and 50ppm acidic. Shift the ph up to 8
But if you have a soil with 1000ppm 500acidic and 500 alkaline then you add 50ppm alkaline and it changes the ratio very little and the result is a oh of 7.1

What is the ppm?Just curious cause my well water is fairly low in PPM but has a ph of about 8.1-8.3 and i see my PH in my potted plant creeping up above 7...and that girl is giving me the middle finger....sooo moody I almost regret cutting clones off of her...thats why i was asking about that fast acting sulfer if anyone was familier with it...thanks for the Info
130ishWhat is the ppm?
