No offense here, but they look like crap. Nodes are way too far apart due to stretching, which means your light(s) are too far away, move them closer. Also, get rid of the aluminum foil, that will lead to hot spots and it has almost zero reflectivity. You're better off painting the walls white, or even cheaper than the foil is getting an emergency blanket from a hardware store, camping store, or even most dollar stores sell them. Last bit of advice, READ more on how to grow. Yes it's a weed and very simple to grow, but as with anything, educate yourself a little bit before you just dive in. If you're going to use CFL's, get more of them, I only see one in your photos, and one is not nearly enough to have any kind of results.
