As I'm planning to build my first DIY stand by using the 2x4 and 2x6, I came across this quandary. How do I know which type of 2x4 or 2x6 I will need for the build? The big box home improvement store have variety types and brands: Top Choice #2, Severe Weather Max#2 (i would appreciate if someone can tell me what #2 grade means)
for example, they have
1) Prime Pressure Treated Lumber

2) Kiln Dried Whitewood Stud
http://www.lowes.com/pd_6003-99899-SG2408SPF___?productId=3604676&pl=1&Ntt=2x4
Which one do I pick?
