Sand is Sand is Sand . . .

The only thing you need to be concerned about is whether the sand gives a
pH other than neutral (pH 7) when you add it to water. Coarse grained or
fine grained - it doesn't matter. Sand is sand. Any ground up rock that
does not dissolve in water and doesn't change the pH is OK to grow plants
in.
