It's honestly a pain in the butt to rig a bunch of CFL's when a 150w HPS would be much better and likely cheaper to purchase. Look at sunsystems 150w HPS on Amazon. Great for a small cab grow.
To vent the heat you can use an air purifier from Walmart. They draw a lot of air and cost only $40. It will help filter the smell too, I built a holmes air purifier into my veg cab. Works great.
