I use coarse vermiculite. I live in the middle of nowhere, so I ordered vermiculite from Greenhouse Megastore, and coarse is what they had in the big bag. I soak the vermiculite or vermiculite/peat mix and then pour off all the water I can, pressing the mix down with a coffee filter to drain as much excess water as possible. I just mist the surface daily until seeds sprout. I use about half vermiculite and half finely sifted peat for most seeds and dust over the seeds that want to be covered with very finely sifted peat.
