contrary to popular belief, foil is 1 of, if not the worst thing you can use for reflectivity. foil DOES NOT reflect light at all (at least not enough to matter), and actually absorbs it, while reflecting heat. Pick up any growing book and that is the 1st thing it will say about lining your walls while building a room. Also, you need to add WWWAAAYYY more cfl's if you are going to have more than 1 plant! Might I suggest about 6-7 more lights, and build a little area, painted flat white, and BLOW IT UP with 2 plants in a scrog-----works great for stealth, and utilizes all of your available area & lighting. All in all, just keep growing and learning and eventually you will figure out what is best for you and your situation!! HAPPY GROWING!!!!
