Controlling the pH of soil outdoors

So I've been preparing for my grow that i'm starting later in April and I'm confused about how i'm going to control pH. One question is how do you actually test the ph with those strips I have an idea but I wanna be sure. The other thing is once you have pH how do you go about changing it properly, and usually how long does it keep at the correct level? If it helps i'm going to have one area about 6 x 6 feet and another 3x3. The soil is most likely going to be half backyard type of soil and half perlite.

....instead of backyard soil...consider adding garden soil or humus/manure mixed with perlite. Flush it well...(wet it well)...they sell ph soil probes at at Lowes, HD, etc. It would give you some idea of the ph. A little lime might be needed too.

Plants seeds very shallow...and pray...:D
