I am building two raised garden beds for a local preschool as part of my Eagle Scout project. I am planning on using a design similar to one posted on this website, however I will be utilizing 4x4 lumber instead of 6x6. I intend to use Heart grade redwood, but I am not sure which type is best for outdoor construction,
rough cut or surfaced? It's my understanding that rough cut tends to warp as it dries, but I have never really constructed anything for the outdoors before. It'd be nice if the beds looked good, as well, and I'm not sure how "rough" looking rough cut lumber ends up being once the project is all put together.
