And also, would i be better off getting fluorescent over an HPS (under the assumption that whatever light i get, it will be used for the entire life cycle)? Are fluorescents cheaper to run?
3) One more question actually. I notice that PH is important, and i often see people saying "adjust your ph". How exactly does one adjust the PH level of the soil?

1. I would make a hole in your cab and run ducts along the side starting at the top and run it along the side. For a carbon filter heres a great way of quickly building one

2. Cfl's are good. Blue spectrum bulbs like daylight are good for vegging, red spectrum bulbs like warm whites are good. Too be honest, bright white bulbs seems to like the best choice because it has a kelvin rating of 3500k and usually the most effiecient lumen wise. If you want to go even more energy effiecient but more with more heat output, get a mh or hps. They each work relatively well on both stages, but if I had to choose one, I'd go with mh because they keep plants short and bushy.
