Arjan ultra haze #2

Hey whats up guys,I was just doing a little research and I think for my next batch I want to throw a couple ultra haze #2 seeds in the ol garden.I seen on youtube a grow video on this strain and they yeilded about 800 some grams on one plant and i believe it was a clone also,shit blew my mind.anyway I use a 400 watt hps and wonder if anybody had any theories to how many grams I can yeild using that?also if anybody knows,I would like to know how it smokes,it looks pretty good from pics i've seen.
