You should have seen reasonable growth by now.  Give the cultures as much
light as you can.  "Near the window" is hard to interpret.  Get them right
up next to the window, if you can.  If you still don't see growth in a
week, and you are sure you have been following the directions that came
with the kit, then set up some new cultures with one to two inches of
topsoil covered with one to two inches of water.
