I've had trouble finding organic seed-starting mixes around here, too; the potting soil doesn't seem fine enough for tiny tomato and pepper seeds. I just ordered some online from Territorial Seeds and that should do me for this season.

I never thought about using those aluminum roasting pans; I'll bet you could put them on a heating mat, too.

How do you make sure that your varieties don't get mixed up, though? I used to start all my seeds in the Gardeners' Supply styrofoam APS system, but it's not compatible with bottom heat, so I tried Park's BioDome and didn't like being limited to only one seed per cell. I didn't have enough spares when sowbugs cut down my young seedlings after I planted them out. So I'm looking for an alternative this year. In the other two systems I either numbered the rows or used little sticks for labels, and I haven't decided how to do it if I use more of a free-sowing style.
