Stadium Grow

Hi,
I had just built myself a nice stadium setup in a 10 foot by 6 foot area, using a 6.5 foot tall 2x4 frame and with 5 2x6x10 shelves on each side. I used panda film to cover the frame up with on the outside (obviously white is facing the inside of the room. I also am using 3 hps bulbs(bare, with no reflective fixture) hung vertically from the roof of the grow room in a row spaced about 2 feet apart. And am using 2 fans. I'm using 1 gallon grow bags and soil.
I had purchased 75 feminized seeds (40 strawberry haze 30 trainwreck and 5 sweet tooth) as well as 10 regular big bud seeds. I'm planning on germinating all 85 seeds at the same time and vegging them for about 2-3 weeks under 2 1000 watt and 1 400 watt hps lamp for a 18/6 cycle, and then flowering for an additional 7-9 weeks using a 12/12 cycle. What can i expect the average yield per plant to be if all goes well? Any help ,criticisms, comments, advice will be gratefully appreciated!
Thanks.

I'm about to start a stadium in the next few weeks once my mothers are ready to be cloned off of.

Do you have any pictures or is it identical to North Farmer/Head Bang Rockers stadium?

Vegging the plants for that long in a 1 gallon grow bag seems dangerous because I feel like they might get root bound in such a small container. Also, I think it would be incredibly hard to hold up such huge plants. I see a lot of string in your future to support the weight of the plants.

NorthernFarmer said that they got 14 pounds off of 4000 watts once when they vegged them out for 4 weeks and a few other circumstances. I'd look that up if you are trying to get such a huge yield.
