I basically have two rooms set up.

1st room: 6ft/sq (3x2) - The big ladies
Lighting consists of a single 400w Metal Halide cheap $45NZD (about $30USD)
4000 Kelvin
New-ish lamp - around 36000 Lumens

2nd room: 6ft/sq (4x1.5) - Single stick clones
Lighting consists of 6x40w T8 Fluoro tubes and 10x20W Spiral CFL's
Warm White - 2700Kelvin
All new tubes and bulbs - around 35000 Lumens all up

Feeding is the same for both sets of ladies.
Some people may argue with my feeding regime but it works for me.
I use the following...
Nature's Own - Super Grow and Super Bloom
Earth Juice - Grow and Bloom
Superthrive in every watering regardless of feeding.
Now for the controvertial bit..
I feed double the recommended dose half as often.
Meaning the nutes state to use 5ml once a week.
I use 10ml of the Natures Own and another 10ml of the Earth Juice once every two weeks. And PH'd water for everything in between + superthrive.
I have no nute burn, constant and steady great growth.
No issues whatsoever.

Medium:
Potting mix from the Switched on Gardner - Our local hydro/grow guys (75%)
Added to this is a perlite/vermiculite blend (20%)
Worm castings (5%)
Dolomite lime for the vegging soil mix and potash for the flowering mix (as required)

Not much else to say really.
Lighting schedule was initially 24/0 for the first couple weeks.
Slowing down to 20/4 for the next couple weeks
Then on to 18/6 for the remainder of Veg
No need to state really but 12/12 for flower

They're doing bloody well for my 2nd ever grow.
Check the link in the first post above to get an idea of how badly I did last time compared to this effort.
