Amateur of outdoor but 1st timer at indoor?

How much would it cost to set up a simple grow box only sustaining about 2 plants, I allready have built a 2x1 box that is 6 feet tall it's painted white on the inside. This would be my first grow so I'm not trying to over-due it, just get what I really need and I think I'm going to try the SCROG method, I've allready aqquired some Indica clones and I've just been leaving them outside for now but I'd really like to move them in as soon as possible.

(BTW I have a coupple CFL's laying around but that's it would that be enough to veg it for about a week untill I get what I need to sustain it?)
