How many plants under 1200w hps

I NEED HELP WITH THIS ONE RIU, SO MANY CAN I THROW UNDER 1200W HPS? AND ALSO WHAT KIND OF YEILD WILL I EXPECT I WILL BE USING 2X 600W HPS WILL BE VEGGING FOR 2MNTHS STRAINS ARE WHITE WIDOW,MASTER KUSH,SUPER LEMON HAZE,BLUE BERRY GUM,CHEMDOG,RED DIESEL X CHEESE HAMMERHEAD X CHEESE. I WILL BE ALSO USING FOX FARM FULL LINE UP, THANKS EVERYONE APPRECIATE YOUR FEED BACK.

i veg for 3 weeks and flower for 2 months from seed 2x600w with 12 plants total. but i can go to 16 if i am looking for plants with heavy tops only.
vegging for 2 months you are wasting time small plants with 2 ounce each plant 32 ounce every 11 weeks from seed or 8 weeks from clone gives me 16 ounces every month. 4 ounces a week which is £1400 per week gbp in street deals uk. ($2241) per week.
but that is only my opinion not an exact science.

im gonna say anywhere from 10 to 15.. just try to think rule of thumb 85 watts per plant. give or take 15w

5-6 monsters in 10gal pots. trained well.

In my last grow i got qp off 1 plant under 150w hps and thanks for replying greatly appreciate it
