Forum:How long do you farm for on average?

i was wondering how long do you guys farm for. and also at what point do you stop? do you stop when you find a pearlescent?, when you get bored, when something else comes up?, or when you go to sleep? i myself dont do much farming. when i do play its about 1 - 2 hours if im on my own, and 2+ when im playing with other people, if i can find someone to play with. i sometimes stop farming crawmerax when i find a pearlescent and finish off my farming run with a loot run.
