Anyone have any clues where I could pick up some? Or any alternative that would hold the same value for mixing with Spagnum moss? I've got a large quatity of the moss and failed to realize that it wasn't true Peat moss till after I opened to begin my terrarium. Now I need some of the sand to mix so it has the drainage effect desired, but am not certain where I can get some, or what the alternatives where. Next time I will just have to purchase some of the premade mix offered, but for now I wanna use as much of what I have as possible before tossing it.
