i got the 1000w hps but i am going to move them into a spare bedroom near a window so i can vent all the hot air out the window. im going to build a little room near the window btw. like say a 8'longx2'deepx8'tall and exhaust the air out of a window and bring in air from another window. is it possible to get these plants as big as i want with lst? like even make it take up the whole room hypothetically speaking. will they keep growing or is it on genetics? btw if i were able to grow a 6 footer how much do you think my possible yield could be?
