Listen to stoked, he's got it right. Fill those containers up with as much soil as you can but then be careful not to overwater because the buried part of the stem will rot and your plants will die. Have the fan on as high and close as it will go without blowing your seedlings over 90 degrees. Get those leaves fluttering. Do those things and keep the light where it is for awhile and you will be okay.
