It should show signs of growth within the next two days if it was planted half inch deep.. if it takes any longer then most likely it is dead :\ good luck buddy
My best say in this is to go with sunlight until you upgrade to a better light setup? and for water just give it a few drops like every 6 hours, thats what i did in my first week or so and it worked pretty well i would say, goodluck with this ! :)
