What your guess for average yield for this environment?

So i know the environment has a lot to do with how many OZ per plant i get so i included the main bits below:

tent: secret jading DR240W (120W x 240L x 200H)
lights: 2 x HPS 600w
fans: 8 inch out, 6 inch in
medium: clay balls
method: Wilma XL 8 x 25L pots
nuets: canna aqua (and all the trimmings recommended by canna grow chart for these nuets)

So that gives you a rough idea of my environment and the strains i am growing are

BRAND: serious seeds
type: 4 x white russian and 4 x serious happiness

So back to the original question, what do you think the average amount of oz's in this grow setup would be?

Secret Jardins grows the heaviest marijuanas, about a pound for you

:/

anywhere from 8 to 16 onzes.. figure an onze to 2ozs a plant is average with two week veg time.. boils down to your ability really.

About a pound

Your question is partially valid. Its a lot to do with strain type, soil/hydro, organic/not organic. Watering and not overwatering, moon phases, butterfly in Asia, etc, etc, etc.
Unfortunately there's no possible way to give you an answer.
So, about a pound.
