Over at Tomatoville there's a thread discussing using Diatomaceous Earth as a seed starting medium.

Those who have tried it report high success rates.
DE is a mineral and is sold in auto supply stores as Ultrasorb. (Nothing else added just DE)

I'm going to be starting some seeds soon in the Master Gardener greenhouse and am going to experiment with DE and a regular seed starting mix and see how it goes.

Is this a coarse form of DE?

The type I purchased was used for insect control and is a find powdery dust. Kristi

I have a 50lb sack of DE that is agricultural grade and I add it to my cattle's feed from time to time. It's way too powdery to be used for seed starting, I think.
