it really all depends on how much space you have, how long you veg, and how you treat the ladies. i am not an expert in growing but i just recently completed a second harvest with a buddy of mine. he only has a 2.5 x 2.5 space with a 250 w/hps and the final dried weight was around 7 oz. that is a pretty good yeild with bag seed. they are mostly sativa which makes this yeild even better. i have really just been reading and soaking up all of this knowledge, smoking and telling my friend how he can variate his current operation. it is soooo much fun reading and implementing all of the strategies that make these plants dank as a moo foo.
