The hypertufa mixes used in the troughs shown.

1 part Portland cement
1 part perlite
1 part sand

1 part Portland cement
1 part sphagnum moss
1 part sand

Material you will need:

Portland cement
vermiculite or perlite or sphagnum moss
rubber gloves
dust mask
container to mix hypertufa mix in
wire brush
board or other flat surface to work on
plastic bag
chisel or knife
spray bottle

Treatment of Trough:

Allow to dry slowly in a shaded spot 3-4 weeks or in big plastic bag with humidity under sun.  Mist with water if needed to keep moist.  The biggest failure in making a trough is trying to unmold it before it has cured long enough.  Brush with stiff wire brush to remove sharp edges and smooth look of poured concrete.  Score sides with chisel or knife.
