Ah right ok mate I might be over watering them then might be why the roots aren't growing to search for water
the easiest way I've germinated seeds is put then in soil nice and moist and put them in the center rack of your oven with a humidity dome and turn on the oven light. this brings up the temp in your oven to the proper temp for germinating and doesn't over heat. (read and article in Harrowsmith Magazine on germinating seeds, and it works)
