Diatomaceous Earth as a seed starting medium

No fertilizer yet. I usually don't fertilize until first true leaves are larger.

I have a similar observation with respect to growth and I made sure to put it in my notes for next year. I didn't really notice a difference with germination, but I do pre-germinate all my seed.
Growth was definitely slower without the "spurts" you typically see. Slower growth was beneficial to me with respect to grafting though, enabled me to get better matches.

PS - I did do a side by side of DE pre-charged with SeaStart 0-4-4 and without. No differential in growth to true leaf stage.
