hey guy's can you answer a question for me

hey riu a friend of mine just gave me 3 600w hps and i'm going to set up another grow room which will be about 9x9.....now my question is do you think it's possible for me to harvest around 2 1/2 lbs.....i will be using ffof soil and ff nutes i will be vegging for 6wks.......ok i know you guys can't tell me an exact yield but i wanted to know if it was possible or what would be me the most likely yield........my other grow room has a 600 and 400 hps that i'm doing a sog in and it gives me about a lb or a little under....ty

3 600w= 1800w the ideal grow is gram per watt so it is possible to get your 2.5lbs if everything goes well

Depends on strain to what you growing?

hopefully i will be growing larry og and c99 if there in stock....

dem is some tig azz bitties!

I grow Larry og it's a low yielder top early low stress train big bushes will yield you more.

ty jdubb appreciate it
