Jet, I like the setup, man. Pretty ingenius. Your plants look good but are a little stretched. As someone else pointed out, you want to get the plants closer to the lights, about 2". Also, you want to add some side lighting as well, that would help with the stretching. My biggest concern about your grow is the density of the buds you'll get. I don't think you are getting sufficient light down into the canopy. You may want to consider a SOG or simply cut back the smaller branches lower down on the plants. This way, they will focus their energies on the main colas. Where are you venting your smell to and are you scrubbing it at all?
