Grow room help please

Hello there once again.
I know i've been bothering you ppl with dumbass questions and projects but this time is for real.

I've been pondering all the hypothesis and reached the ultimate project for my goals.

Decided to grow this one http://www.royalqueenseeds.com/122-white-widow.html because they'r famous, small and potent.

Going to grow in a kind of tent inside a room. Wooden structure, plastic casing with mylar in the inside. Any ideas are welcome.

I have a little wooden box with these measurements:

And i would like to know if i can keep there a mother plant (white widow). Thinking of putting one CFL 125W. Is it enough? How do i keep it always small?!

Now, only want to use 1mx2mx2m of space and white widows aren't that tall so i tought i could use 2 layers. One for vegetation and other for bloom/floration.
Now here's when i have many questions and didnt get many answers searching in the internet...

This is my project:

Vegetation plants are smaller then the ones on the flowering stage so making the vegetation room smaller = space optimization. But do they fit in 80 cm with pot and lights included?

Also, how many plants should i fit per m2? I was thinking about 4 plants per square meter, what do you think?
How many kg of grow medium should i use per plant if im thinking to grow 4 plants per square meter?

And about lights, im thinking of 125w CFL on the mother plant, 1 600w MH per square meter on the vegetation area and 1 600wHPS per square meter on the flowering area. Am i doing this right?

Please, any tips would be helpfull

Thanks.

Advanced paint skills, i know. Hope you understand them..

btw, mother box is 2.49' tall, 1.48' wide and 2' deep.

the big closet is 6.56'tall, 6.56' wide and 3.28' deep.
vegetation 2.63' tall
floration 3.94' tall

sorry if not expressing myself right
