That wood from Stimson is the worst ever. I don't think you can buy worse. I've used all sorts in my life and HD consistently has lumber that cannot even be used to start fires until you dry it.

Plywood is fine, but if you need anything you build to last, buy pressure treated at HD, or buy plain lumber somewhere else.

(I bought some 2x4s for a non-permanent project during the pandemic. It was so soft and wet that when I fired a railgun into one of the pieces, the nail went all the way through. That should not happen)
