Well, throughout my reading I've pretty much come up with an idea. Using cardboard box, aluminum foil, and a small fan.

Would this work? The things I'm mostly confused about though are the specifics.

I'm looking to grow 1-2 plants at a time, nothing too incredible. So my questions would be, what type of lights do I need to purchase? And even furthermore, how would I go about installing the lights and the ventilation system(do I need one?)
