I only have one small grow tent in the living space of my new house.  It resides in the computer room where I write these daily blog posts.   I only keep my experimental plants and other hopefuls in here.  It is lit with one 15oW HPS  bulb and one single T-5 striplight.  Here is a photo from inside after cleaning it this past weekend.
