5x4x2 Grow Box Need Suggestions

Hey I am getting ready to build a grow box that is 5 foot tall,4 foot wide,and 2 feet from front to back.Can anyone help me out with lighting ideas,and ventilation.

That's 8 sq ft so in cfls you would want perhaps 600w if you are growing it all. Your lights could grow along as the square footage actually in plants grows.

Perfect has long has you flower at about a foot tall these dimensions are fine.but you will need a decent light for this space.

Any ideas for light?Where can I find HPS light?
