Well I have an open window that's not far from the fan so fresh air isn't an issue. After I get the cords I'll probably put about eight of these lights in there. I'm using "Moisture Control" Miracle Grow, I don't really plan on using any nutes but maybe I will find something worth using. Where do I get the Superthrive, I have seen that in quite a few posts. The Carpet should be okay too after I get to the point of transplanting. Also there is a shelf with a clothes hangar bar going accross the top in the closet I was going to run the lights down from. The closet is 3x3x7 which isn't really enough room for seven plants but they aren't bag seeds either i'll be lucky to get two females probably. I guess we'll see what happens!
