Looks good, if it's a cfl light i'd stick it real close to top and/or have a fan blowing around it if stretching too much.
I myself do both above and I sometimes use sum garden wire n make a U shape n bend stem,then pin into soil.. (mini lst ,if you like) - the tops bend up within a cple of hrs+stem strengthens too. Any combination til they're bigger will do.
Hope sum of this helps..
