I'm a heretic too, Alex! I think sterile media make for weak plants. I don't have any science to back it up, just observation.

I've been starting plants in a mix of good soil from my beds and my own
finished compost since 1991. I mix it 50/50 because I have sandy soil that
doesn't hold water. I know this is heresy, but it works. I've had no
disease, I've had strong, healthy plants that transplant well.
I know everyone says to use a sterile mix or you'll get diseased plants, but
it just ain't so. I had a student in Organic Farming class whose son applied
the info from class for his science project. He planted tomatoes in sterile
starting mix, some in potting with compost and some in garden soil/compost
mix. He then induced "damping off" in the greenhouse by lowering temps,
cutting are movement and over watering. The result- 100% death in potting
mix, 50% death in pot/comp., a few plants lost in soil/compost.
Another trick for faster more complete germination. Cover seeds with fine
compost. The humic acids will stimulate faster, better germination. Try your
own experiment with it.
If you MUST use potting soil, add about 15% worm castings. Research has
shown that the plants grow better with these in mix.
