bobbyhardcore,

I have read many times that a good goal to try and reach is 1 gram per watt. I am growing for my first time and would be very happy if I reached that. I plan on only getting half that and I am even using CO2. I am runnin to two 430 watt lights so 860 total. If I can ever pull off 860 grams per cycle I will be VERY happy. So I think a good guess for a fisrt time grower would be a half gram per watt. Hope this helps.
