lighting Indoor light requirements

I'm currently working out a design for a shelving system for growing seedlings and mature plants indoors. I'm going to hang lights from the bottoms of the shelves to illuminate plants below...I've already figured out I can use shop lights for the seedling shelves (I figure 4 T8's should provide plenty of light for a shelf measuring 48" x 18"), but I was wondering if it would be worth my while to invest in a HID light for growing mature plants on another shelf. If so, what's an ideal output for an area of 6 square feet, and what distance from the plants should the light be positioned? If the shelving system is in an open space, will I still need to invest in an inline fan for the HID light fixture? I've looked for answers, but couldn't find anything too definitive. I apologize if I've overlooked relevant information.
 
Hi DM, 
 
I'm pretty happy with the LED shop lights I use - check them out here - http://thehotpepper.com/topic/45510-from-new-to-lost-sanity-in-a-few-short-months/page-2#entry1005957
 
Am doing exactly what you are - growing inside in a lit area. I've got a constant fight on my hands in taking off all the flowers, but have yet to let them grow to pods as am going for plant size right now (so mileage may vary - not sure how this will work out). I do know they work well for vegetative growth though and will have the plants throwing out flowers with no issues.
 
30-50watts/square foot of plant canopy will bring a chile to fruit.
 
50 watts/square foot if you use fluorescent, 30 watts/squqare foot  if you use HID
