Might be , I hear that is a high yielding strain. Im growing BB now too. But maybe if you sog or scrog them with lil to no veg you could do it. I have a 4x4 tent and a 600w hps , I got one beast(vk -lst'd) in there now and she is damn near taking up the whole space. If you plan to veg I would say no more than 6. Again just my 2 cents. Good Luck!
