This is similar to what I'm doing. But be aware that if your one plant turns out to be a male, you'll have to start all over again, which sucks, but it is safer legal wise. Anyhow, I'd say you should have at least three feet of growing space, and about 100 watts worth of CFLs. You can start 12/12 as early as possible, like in two weeks after the sprout emerges to reduce too much growth, and tie the plant down as needed so that it doesn't grow directly upward.
