I buy the moss and vermiculite in 8 qt bags. My mixture is 8qts of moss, 8qts vermiculite, 8qts portland cement and 8qts of water. If you want a more cement like color, you just need to cut back on the moss. More water can be added to get the mixture the way you want it. You could also add concrete coloring if you want a specific color.
