I ran my own independent experiments, usually designed to help a graduate student with one of his projects, and was then left to my own devices. If it was done in 2-3 hours, it was because the cultures needed to incubate overnight anyway.
I did group lab work with an instructor as well, but my university had a pretty vibrant undergraduate research program.
