soooo..... gotta question. if i have say a 5x5x6 flower room w/ a 600w hps. can two plants achieve this gram per watt. in my case they are quite bushy. i feel a lil wild "thread jackin" but im in a similiar shaped boat.
Don't matter how many plants you have just depends on the size of the plant and how your grow goes.
I see one guy who got 450g off 1 plant under a 400w light
Where did you get the white widow from? Have you seen it grow b4? Just wondering if you know it to be a big yielder. If I had to take a guess I would say 2-3oz a plant. 2oz of good stuff and another oz of decent stuff. Thats my 2 cents.
Not sure who WW it is. I just got some cutting of a friend. First time at growing this strain but I can tell you it's very hardy. Can with stand a lot!!
I'm hoping for at least 36oz
I worked in a few greenhouses back in college and we had some 'secret' grow sites around the facility. And we used to play 'guess the yield'. Guy who was closest got first smoke. 
What a cool game. Great college you went then. Everyone says what a stupid question but first time growers really want to have a good idea of what they might get under there circumstance and the pro's should try to help even though they think its stupid
