Ph up and down for soil?

What's the best product to buy for PH levels if I'm growing in soil?
Can I use the same ones from a hydroponic set up? I was looking at these: http://www.htgsupply.com/viewproduct.asp?productID=47513

Will that work for soil?

That will work fine. That is used to adjust water not the soil. Just in case you were thinking that.

yep its what i use

So how do I adjust the soil PH?

Kind of depends. What is your ph of the soil?

I don;t know if it is me but it seems like when I add nutes it uaually sets the pH right on to what I need. It sumtimes gets off though and I have to flush.

Planning on using Fox Farm Ocean Forest Potting Mix
