Growing medium

Lots of suggestions for growing medium.

I don't see Vermiculite in anyone -elses- medium. Is there a reason for that?

My medium is 50% commercial potting mix (usually Miracle Grow), 10% coarse sand, 10% vermiculite, 10% chicken gravel, 10% perlite, 5% coir, 5% compost.

I'll typically add extra vermiculite to the top inch or so if sowing seeds, and use vermiculite to cover most seeds.

I add some extra sand in the case of plants that require extra good drainage.
