You had a good sized closet, from what I remember. Go to Dr. chronic, and review the different strains. I think that a good cross would be nice. I don't know much about the medi. side. Maybe something with White widow or nirvana. How are you going to grow? Hydro/soil?If cost is a factor, there are tons of DIY threads. How wide is your room? Do you want a perpetual harvest? Check out Earl's grows, there good. Heath is the man when it comes to hydro. Soil is good, just too messy for me. You have an air cooled light, so a stadium is kinda out, unless your willing to change it up a bit. With the size of fan your planning on, you could remove the socket and hang it vert. ( need a vertical bulb). Sometimes the hydro store sells used bulbs for half off. What ever you do research it. Ask Q's Do the math.
