Please help grow tent

I was thinking about growing 1 plant in this a northern light plant and with a 400 watt hps light system with ballast, i was wondering if it would work out alright.http://www.amazon.com/LED-Wholesalers-GYO1001-Reflective-Hydroponic/dp/B00283Q59M/ref=pd_sbs_ol_2

Im sure It will work out just fine as you know the basics(ventilation, light schedules, feeding). Why only one?

You will need a good ventilation system. I have basically the same tent but I run a 250w. I need an inline fan when I get some $. But, I cannot close the tent with the lights on, temp gets way too high. But to give you some inspiration here are my girls...

The reason why I only want to grow one northern light plant is because I live in a place called the ymca and i live in the 3rd floor and i'm a resident and i don't know when the lord will come in or not because he just came in to check the temperature so i'm trying to see if i could maybe hide the tent in my closet or something if he comes in. and do you think it will be fine with odor?

I really hate to discourage anyone from growing ever. But, this seems like too risky of a situation to me. Unless, you never leave the place, you have no idea when the LL is coming in. The only thing I can suggest is changing the lock but I am also sure the Y has rules gainst that.

Yes if you get a carbon filter ..

what if I just get a Ona block and have a febreeze plug in air freshner with good vanalation going through the window in my tent?

Damn, if you really think they might come in there and you arent a medical grower. Not worth the risk at all IMO. I dont really understand...You think they would be cool if they busted you with one plant, but you would be fucked if they found 2? Your grow idea sounds like a bust to me, good luck though.
