Large Octagonal Cedar Planter

Large octagonal planter. The inside dimensions are 33" (l) x 33" (w) x 22.5" (h) . The planter's exterior dimensions are 36" (l) x 36" (w) x 25.5" (h).

I needed a large outdoor planter for my hops vine. They want soil at least 22" across and 20" deep. I started with those dimensions but it grew as I tried to minimize the scrap wood. I fastened it mostly with pocket screws and dowel pins, except for one entire side. I fastened that side from the exterior so I can unscrew it, open the planter, and clean it out.

I'm very novice at designing and at woodworking. I'm positive it's been over designed, and that the project will go faster for you. I uploaded my project notes as an image, but it cuts off the border to all my photos. It also won't save the wood under materials so here:
2x6x10' cedar - 4 planks
2x4x10' cedar - 2 planks
2x4x8' cedar - 1 planks
2x2x8' cedar - 1 plank

In hindsight, it would be cheaper to rip cut 2x4's with a large 45 degree bevel, and use them as interior supports at each of the 8 corners. Then you could change out the thick 2" walls with 1x4's and 1x6's. Although it would save money, I don't think it would be easier than my original approach.
