Windowsill Marijuana

This summer I would love to try growing a couple small auto-flowering plants on my windowsill; just as an experiment. Has anyone tried this before? I'd assume with our daylight hours here they'd grow really well. If you do grow them on the windowsill what tips do you have? I'm planning on turning my plants habitually to ensure that one half isn't ever left in the shadows for a long period of time. It'd be in a south-facing window and most likely I'd have the window open and screened for natural breeze. I could pretty easily monitor temperature and I've grown a lot of other houseplants on my windowsill so I can pretty much guesstimate that it's going to be between 68 and 72 degrees Fahrenheit most of the time. I'm not planning on getting a huge grow, rather I'm just doing it to see how much I could actually get off of a plant by simply treating it like a houseplant on my windowsill.
