one square foot box

i dont have pics atm, but ok. I have a one square foot steel box with a hinged lid. then at the very i top have a 42watt cfl spiral. But my main questions are will this work in 16oz party cups. theres about 6" from the cups and the light. so i planned on trying two VERY small girls. i also need venalation. what i need is an AC fan but since my box is tiny i need a tiny fan. are these available? (cpu fans are not an option i gotta stay with AC). im usually an outdoor grower but since this summer was bad i have to go through winter. plus this looks fun. any help or sugestions please do. ill have pics on the way.

you can pretty much do like a pc grow but in all honesty the payoff is not even worth it. youll end up with about 4 or 5 grams prolly and i dont know about you but i can smoke that in a hour or 2 so definately not worth 2-3 months
