First time Growing, Good sample, Costs, Documentary

so i took my measurements the are is 27.5" by 58" and about 8' feet tall.....

if i multiply length=2.291' x width=4.833' x height=8'
I get about 88.579cfms
If i divide this number by 5 i get about 16.2 (#of CFMS i'll need to clear the grow area in 5 min with fresh air)

so here is my grociers list

1.) The 150 watt HPS MINI grow light 16,000 lumens....w/ warranty w/extra 150watt light.

2.)25'x50" roll of "PANDA FILM" (seal the grow room)

3.) Going with a Growbright 4" Inline fan and corbon filter combo(40 watts 170cfm's, i only need about 60cfms so it think this should be sufficient)

4.) Fox farm liquid soil formula 3-pack

PRICE TAG = $309.75

I've got my fertilizer, lighting, and ventilation... i've been researchin this for over a year and its now buy time so i'm just getting all the equations in order

Now i need to worry about soil, pot size, getting a small fan to help airflow and maybe a couple other small things... (BEROMOETER, THERMOMETER, PH TESTER)

FOR SOIL:

I have heard only good things about earth worm castings, Cocoa peat, pearlite, and foxfarmOean forest potting soil..
I've seen high times growing films, i've seen even various hydro-stores that have there own videos out... i know they have certain mixtures or formulas for creating "the perfect soul mixture" i'm just not sure what i should go with and would like some first hand advice....

any advice will be taken seriously.....

Thank You Much,
Mac

totally wattage = 150+40=190 (not including small circulation fan)
(thanks widow, for turning me to HPS systems)

still a little weary of ordering online...
