Back in her day a decent amount of bud might be a minimum amount of bud now . I wouldn't recommend anything less than 250 watts for flowering..It never hurts to update the way things are done. I think it needs to be done right if possible. Check out the cultivation section.

edit: I just read through the posts and heavens no a heating lamp or w/e that is wont work lol. I'd recommend CFL's or some kind of fluorescents for seedlings and vegetative plants and HID lights (more specifically HPS) for flowering. Or you could just use an HPS for the whole grow. I'm doing it now and it seems to be going pretty well so far.
