I do all of my seeds straight into soil, a good thing to do is put seran wrap over the top of their container to keep the humidity up, also 32 degrees farenheit is way low, if your talking celcius i think that a bit high but i dont want to do the conversion right now cause ive been drinkin it up, now seedlings you want to keep the light a little further away than with established plants and remember once they pop mist em lightly to keep em happy, and be careful about not keeping the soil to wet but dont let it dry out the way that you will with a full on plant.
he towel method is great for figuring out how viable the seeds are but i like to put them directly into soil because about 1 inch down in the pot is pretty much optimal environment for em.
what scunkworm is saying is a perfectly good method but its all preference, remember if they grow your doing it right and you can acheive this a million ways
