is it possible to get 4lbs off 30 plants areo grow

dont know how dumb or educated of question this is but it sounds good to me but if you have a 30 site system is it possible to 4lbs dried off of it . so let me know what u think

64ounces(4lbs) / 30plants = 2.13oz per plant.. If you're new to hydroponics, you probably wont get that the first time, but it's certainly possible, and should be quite easy once you get the hang of things.
