2 ft wide X 8 ft long X 2 ft tall starting 1 ft off the ground.
4 X 4 supports in the center.
2 X 6 aprons all around ...
Now the questions...what are the sides of the planters made of?
Is this just a support for the boxes or will this BE the box?
Wet dirt weighs a lot more than dry or damp dirt.
A sketch will be useful as suggested.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
