thats my plan.. I am an outdoor guy though.. so this winter will be where its at.. My grow room will be powered by solar panels.
2 200 watt bulbs = 400 watt right

Maybe they said 88,000 lumens in the catalog because it's next to the 1000w and they wanted to keep the myth going. But in all fairness it says "approximately".
I missed where he said the square feet of the garden. I've never done them but I thought auto flowers stayed pretty small.
If you are willing to move and turn them daily and keep them close , you can get most of the potential yield with fewer watts than many assume to be essential.
A 600 HPS should be plenty for ten autos for nine weeks , yield will never be huge with these , no matter how many watts you throw at them.

Yea I a not looking for much maybe a bit more then 2 ounces if thats realistic.. I am going to give most of it to my uncle.. I did something disrespectful a few years back and I owe him..
guys, guys, lumens are for humans 
. I disagree with the opinion that a 600W lamp is more efficient than a 1000W lamp. That used to be the case but not anymore!
The best 600W lamp we know does 1170 umol s-1, the best 1000W 2085 umol s-1
So:
600W (+38W for the ballast) that's 1170/638=1.83 umol/W
1000W (60W for the ballast) that's 2085/1060=1.96 umol/W
That is one of the reasons why in Dutch greenhouses most have switched to these 1000W double ended lamps.
In general smaller lamps are not more efficient. A 600W lamp is more efficient than a 400W lamp, a 400W lamp is more efficient than a 250W lamp... if you compare the same type of lamps of course.
btw electricity in Europe is more than 3 times as expensive

Do you have a link to one of those lamps? Are those dual arc lamps?
The price i said is just the price per kwh. There are plenty of other fees. I can't even figure out my bill and have not tried to figure out the real price per kwh. Which would be different for every bill.
Did you mean 2 ounces per plant? Or two ounces, period?
I grew 3.5 oz under 252w of CFL in my first ever grow, from seed with 12 tiny plants (they were planted in 1/4 gallon containers). The tallest plant was 14" from topsoil to tip.
My flower room was 2 sq. ft.
I'm pretty sure that you'll hit 2 ounces unless you neglect your plants to the point of system failure.

yes minimum all together 2 ounces dried + cured. No neglect from me I HAVE to spend lots of time with them.
Even the scabbiest short vegged clone gives around an ounce , ran hundreds this way to select and they all give that in a two litre pot with deliberate stress , you could hardly do worse if those genetics are sound.
Would expect ten ounces if none have to be culled , with decent light and moderate care.

i think my lucalox bulb is higher rated than the 600s posted. great bulb
With all due respect, Sea of Green would never work if what you said is true. There are plenty of people who have done way more than 10 plants with a 250W light and a SoG. The wattage per plant is irrelevant, it's the intensity of the light per square unit(meter, foot, etc). Hypothetically, there are some huge tropical sativas that would even be too big for a 1000W light by themselves if you vegged them long enough. The light you need is totally dependent on how much space you're occupying. Depth is also an important consideration, but less important to worry about in Scrog type setups, or other branchy styles. Sorry to go on about it, but I really dislike axioms. They really hinder science.
