Tips from a fellow enthusiast:

1.) Get a GOOD light. (Checkout the Thinkgrow Model-H for example).

2.) Set up a good hydroponic system, and use timers for your water schedule. (I recommend drips system. And don't forget to flush with water at least twice between feedings to prevent salt build-up)

3.) Use as big of a pot as you can realistically get away with. The bigger your rootball, the bigger your plant and more nutrients it can take up.

4.). Get a GOOD carbon filter and no one will ever know your growing....unless you open your tent...

5.) Get a good tent! You want reflective walls, ventilation ports, cord access, etc.

6.) and lastly...and most importantly, get good genetics. Autos are great for a trial grow, but nothing will ever beat a good photoperiod plant - better yield, better quality, and massive, beautiful, photo-worthy colas.

Follow these basic tips, and I guarantee you'll grow something better than you'll be able to get at most dispensaries.
