6 to 8 x 25w cfl bulbs is enough for one auto. You're running a little low on height unless it's a lowrider or very short auto, but it could work. Heat will be tough to manage. Use a 2-3 gallon pot,
20/4 would be my thoughts. don't mess with it. plant it and in week 4 start feeding bloom nutes. then harvest in 70-80 days. don;t try advanced growing techniques such as topping, just let it grow.
