how much will they produce

i wanted to know what i may expect. I'm running a hydro hut, I'm using a 600 watt light, and using soil for my plants. I am using the three step GH nutrients. on a average what can i expect my 9 plants to produce?????

pics mite help. But i am on my first grow so i do not know. What i heard is like a oz a plant or half a g to the watt. something like that. Somebody who knows more than i please shine some light on this guy. It also all varies by strain and how you grow it. You can use techniques such as supercropping, topping, or lsting.

i would let them veg for about 3 weeks, any more than that and i think you will start to lose density in the buds.
but if you let them go 3 weeks before 12/12 i would expect you can get close to an ounce per plant.
