Where are some places I can purchase pH tests?

Hey, I've decided, since I now have seeds, that I want to take a shot at growing my own marijuana. I know I need soil with a pH rating of 7, but I need to know some basic ideas of where I could buy a pH test. Could any of you give me a suggestion? Could I purchase one at a department store such as Target, or a drug store like Walgreens?



Thanks!

 

You can get ph drop tester stuff at wallyworld, petstores,etc.
If money is not an object, you can grab a cheap digital ph pen.
goodluck with it.
