Fill the box with Mel's Mix until it covers the bottom and then water. (Do this three times until your box is full.) Then, add your wood lath grid and plant!
Stack your lumber like steps. Once you drill the top piece, slide the board back to expose the next one.
All types of lumber come in 8-foot lengths and multiples of 2 feet thereafter. Since most SFGs will be 4X4 feet, ask the lumber company to cut your 8-foot-long wood in half when you buy it. They usually do this for free. Then its easier to take home, quicker to assemble, and eliminates any need for sawing. All types of wood can be used: pine, fir, cedar, or even redwood (which is more expensive but longer-lasting), but don't use treated lumber.
