average yield?

hi my 1st grow i have 8 plants 5 bluberry 3 bubba kush 1 week into 12/12 unber a 600 watt hps with 2 cfls for side lighting, using terra canna nutes, canna soil, 16 " fan and a 4" extractor to attic, i know an exact answer is out of the question but what would i expect to yield(dry) the room is approx 5ft by 2.5ft and 9ft high complettely black and whited and plants are currently around 20"

There is such a wide range of answers and some seem soo outrageous they probably are. I am happy with 3 oz's per plant on average. It really depends on alot, especially WHEN you go into bloom, I like to wait til they are about 24" in height, but again that can depend on strain, growing conditions, how vigilant you are in your care for them etc..

thanks my goal 1st time rnd was 2oz dry per plant
