Help needed : Hps Size for heat Control

Hey guys, I've got a grow cabinet design I wanted to throw by you, It would be 100% sealed and the main door would be opened every night for 1-2 hours.

Here is a quick Reference of the grow Cabinet:


Now, The one thing you'll see that I am missing is the HPS Light Located in smack dead center of the Flower cab.

I plan to put in two Oscilating tower Fans for maximum distribution of air from left to right.
- The Large Circle in the middle of the flower cab is the Exhaust of a very small 6-8000 btu portable air conditioner which will be outfitted with a cable thermometer planted in the flower cab and not in the room next door (where the AC unit will be).

Lights : 8 CfL's 2700k Phillips 27w (true amount pulled) ~1603 Lumens

8 x 1603 = 12824 total Lumens.

If Cabinet is 11.025 sq.feet than so far:

12824 / 11.025 = 1163.17 Lumens per sq.ft

If my memory serves me correctly, any plant needs roughly 1500-2000 lumen per sq.foot to properly function and grow.

That means I am missing 336.83 - 836.83 additional lumens per square feet or

336.83 x 11.025 = 3713.55 Total Missing Optimal Lumens
to
836.83 x 11.025 = 9226.05 Total Missing Optimal Lumens

Therefor I am in need of a HPS output of roughly 3713.55 to 9226.05 Lumens.

Now, before I go on to the main question, I need to address these two problems I see so far, and Please add some more because If there is something wrong, I'd rather fix it before I start it than after i've sunk money into it.

Heat - Will basically be dependant upon the air conditioner...

Height - Since I have a wide and long cabinet, I plan to use SOG but more of a bonsai approach (Like a christmas tree on its side with all the side branches now making individual main cola's reaching for the hps)
- Choosing Fat, stocky sativas with multiple buds (Apollo11 and Big bud)

Since I am a heavy daily smoker, I would be following the perpetual grow with a personal consumption of 1 plant a week harvest. Size doesn't matter to me at the moment, only success in my ability to raise, and then experiment with, my personal plants which would be on a weekly rotation (Apollo week 1, big bud 2, a 3, b 4.. repeat).

Wattage is a issue, so I plan to change all the cfl's and instal timers on my large television that also has a vcr, sound system and Cable (Must be a big Watt drain) on usually 24/7 thanks to my brother.

With that, in mind what wattage of HPS and if possible brand would be best for those dense sativas with not a lot of height to grow with but tons of width and space to make multiple buds.

Thank you in advanced, I really like this forum and hope it can help me solve my riddle of the properly balanced hps.

 

Hey guys. I've done some research and will be going with Hortilux 250 Watt HPS

Since I was missing 336.83 - 836.83 additional lumens per square feet

30500 / 11.025 = 2766.44 Additional lumens per square foot with HPS.



So it looks like I grossely under-exagerated the amount of lumens produced by hps, but having over 2000 more lumens will just pump out thicker fatter juicier buds


Hmm I cut out a shit load of wattage too... seeing as I'd only be using 450~ watts in flower plus an additional 100~ in Veg and 100-150~ in A/C w/ Fans.

700 watts total..... replacing 12-20 60 watt bulbs and the timer turning off the wasted electricity due to the tv etc. should be enough to even it out or even lessen our electricity bill.

Now that's what I call destiny
