That does sound reasonable, but I've never actually built a raised bed
myself. Pressure treated lumber can
leach arsonic into the soil. If the composite stuff is reasonably inert
(and I believe it is) then you are good
to go. I will be using some rot resistant wood starting in about a week.

i'm going to start some raised-bed gardens, too. how 'bout if i use, instead of
pressure-treated lumber, i use composite decking? supposedly it's made of "wood
fiber and resins." it's more expensive, but i'd be buying one 16-foot board for
each box (4x4)--so that's around $27 per box. sound reasonable?
