When making your own pots, remember size equals soil needed to fill. It is easy to make big pots. Filling them, not so much.

Cylinder Volume {in cubic inches} = 3.14159265 x radius squared x height

. . . . and to put that into gallons, you would divide by 231.

So a pot 32 inches across and 18 inches high would be 62 2/3 gallons.

3.14159265 X (16 X 16) X 18 / 231 = 62.668
I am doing a 5x5x2' box. I believe that is 2 yards worth of soil if I did the math right...which is a Lil under 400 gallons. Is that right?
