Help raising PH

I have a plant growing in soil that is showing a soil PH of about 6.2. I was just wondering what I should use and how I add these materials to raise the PH to around 6.8? Suggestions are greatly appreciated!

Just ph your water to around 7.0, it will pull the soil up with it....check the ph of the runoff water to verify. Once the situation is corrected, adjust your water ph accordingly.

edit: You don't need to get to 6.8, 6.5 is great for soil. JMHO

You can get either Ph Up or Ph Down from Hydro shops Hope this helps

Correct....use that to ph your water, do not add it directly to soil.
