Put the seeds in between a couple of wet paper towels in some sort of tupperware container. Put the container someplace warm. The seeds should be relatively dark. You don't need light. I use the top of my fridge.

Check everyday to make sure:
a) the paper towels aren't dry
b) the seeds have germinated.

Once you have germination, plant in your medium right away. If you leave it a day the tap root will grow quite long and it's more trouble.

Should take 24-48 hours, at the most three days.
