Guides say 4' x 4', from experience I fell like 3' x 3' is optimal, about 10 plants or so.

dude check out the link in my sig for my grow.
I have a grow cabinet that is aporox 20in x 36in and i have a 400 w in there.
I have 5 girls in there right now in their 2nd day of flowering.
The 400 w is a bit tricky in the begining stages ( I had my seedlings under my 400w MH) and it caused a bit of buring, not nute burn but regular burn.
However, my girls lived though it and the result has been some crazy condenced growth.

As for your like standards, when i was planning my grow cabinet I found this helpful

however, you need to think about your spacial constraints and lumen penetration in terms of height.

well i'd say that depends on the hood you go with.it's been my experience that 2'6''x2'6'' with out a hood worked great for me.all direct light that way and less heat.

Strait up bulb, no reflector, in a cab 2'6x2'6 and how tall?
Without a shade there's less heat ?
I have a white shade arched and open at both ends.
