Cool thread .... the cardboard is a great idea .... I know the idea of the moss was to make it lighter and I think that is the idea for the vermiculite. Wonder if there are any other fillers that worked as well but are cheaper . You know you can stain cement if you want it darker. I know some folks you some kind of acid etch as well. This is so clever .... Gene
