Three hours of lab a week?
Four hours of lab a week?
Independent projects with students coming in at night and on weekends?
How much is enough?

I remember well my organic chemistry lab while I was a biology major in college. The lab met for four hours a week for the whole semester, which at my college was 14 weeks long.
