You can use the acid soil to grow blueberries.I just used my gro line soil ph meter for the first time and I checked my super soil's ph outside in my smart pots and its ranging from 4.5 to 5.5... should I raise it? and what should I use/ add to raise the ph of the soil to 6.5, 7 ?

Blueberries, Azeleas, Hydrangeas all like acidic soils... but that is pretty acidic even for them. The acid rain in Northern Canada damn near killed off large parts of the forest up there in the 70s... including a lot of blueberries. It was a big deal as the berries are a ig part of the diet up there for critters. This is what I was thinking when I made my post, although I don't know what the Ph of the acid rain was.You can use the acid soil to grow blueberries.
That's one of those probe meters, they are notoriously inaccurate, I wouldn't trust itI just used my gro line soil ph meter for the first time and I checked my super soil's ph outside in my smart pots and its ranging from 4.5 to 5.5... should I raise it? and what should I use/ add to raise the ph of the soil to 6.5, 7 ?

Stones,lime and such raise the PH,also ashes.....But what is the containing of that super soil?Usually(to me) to raise it is the easiest but to lower it is harder........:)But yes,first check it that meter is acurate before take action on the soil and feeding,also check your plants!!!!!!I just used my gro line soil ph meter for the first time and I checked my super soil's ph outside in my smart pots and its ranging from 4.5 to 5.5... should I raise it? and what should I use/ add to raise the ph of the soil to 6.5, 7 ?

Mines seems right on.That's one of those probe meters, they are notoriously inaccurate, I wouldn't trust it
Yes Lime will increase ph , iron will lower it .Stones,lime and such raise the PH,also ashes.....But what is the containing of that super soil?Usually(to me) to raise it is the easiest but to lower it is harder........:)But yes,first check it that meter is acurate before take action on the soil and feeding,also check your plants!!!!!!
The probe might be accurate when measuring a solution's Ph, but when measuring in a growing medium, ther is a lot of organic matter that can influence the reading. A more accurate way would be to collect the runoff and test it, since it will be in solution that is opretty much the same as the root zone. You might even see a difference between the first part of the runoff and after it ran for a little.Mines seems right on.

I was just being a smart ass as these meters are completely useless and sit at 7 no matter what. (Even in a box of baking soda, with a pH of 9. It was a joke.)The probe might be accurate when measuring a solution's Ph, but when measuring in a growing medium, ther is a lot of organic matter that can influence the reading.

I have work in the Horticultural industry for many many years never once have seen or will I see one on those static ph7 meters in use we use the dye n powder test it never fails .I was just being a smart ass as these meters are completely useless and sit at 7 no matter what.

That is what he is aiming for by his post he was asking how to raise it from 5.5 , as answered Lime .For soil you want your pH between 6.0 - 7.0
