I agree with Rick, other than that it seems easier for students at night cause they tend to scan better with less outside distractions, and usually the air is nice and smooth to boot. I am a bit uncertain about the solo stalls at night though, not so sure thats a great idea. A 20 hour student would perhaps have some difficulty at night with lack of outside reference and not yet comfortable with instrument flight.
