you are going to have to leave your closet door open if you run a HPS light. It will get to hot in there. You should do with some t-5s, that way you can leave the door shut and open it every couple hours to get fresh air in there. But you are still going to have to deal with the smell. I have an HPS and tried to close my door, raised the temps up real high. Luckly I live in a house so I was able to cut holes in my wall and ceiling on my second grow. Good luck!
