When I made mine I decided to ignore the water for my volume calculation
since I figured, when it dried there would be a small amount of shrinkage.
In actual fact, the adding the water didn't seem to make much difference to
the volume at all. Now, My planter is A LOT smaller than yours. Perhaps
it is just a matter of degree. Or maybe it has something to do with the
chemistry of adding water to cement.

By my calculations, the total volume of cement, sand, and peat moss you
will need is 11.4 (for simplicity use 11.5) US gallons.
That's a big container! Have you considered how you're going to move it?
Hypertufa is very heavy.
