Mostly I like vermiculite for covering seeds. It retains moisture well and dries out to a different color and texture on top, so I know when to water it. Best of all, similar to perlite, it does not crust over like peat, blocking sprouts from breaking through.

there are different grades of vermiculite. I tried the Menards stuff but it was very fine. Finer than I wanted. it also comes in coarse which is quite a bit larger... almost "crumble" size, which I went back to my greenhouse/produce materials supplier to buy. Perlite and vermiculite comes in a 4 cu.ft bag if you can find a local supplier.
