I'm almost finished with the construction of my first 4x8 bed. It sits on concrete and is raised by 2 courses of cinder blocks with a plywood bottom and 2x12 sides. I just need to drill the drainage holes but I'm not sure how many and what size they should be. Any suggestions?

The smaller the wholes the more you should drill. 1/2" to 3/4" should be large enough for the holes. I would put one hole per square foot at the very least.
