first, at 9 days old, your seedlings need almost no light, when they do want more light, useing cool lights (5000Kelvin to 6500Kelvin) is best for vegging (you'll want SOME warm light {1900Kelvin to 3000Kelvin}, maybe a 4 to 1 ratio, watt for watt). when they're ready for flowering you'll want to go in the other direction with mostly warm (red) lights, about a 3 to 1 ratio (cool, or blue produces less intense light).
second, and don't take this the wrong way but, vacuum that rug man, carpets are a great place for mold spores and who knows what else.
third, take a look at some of the Rubbermaid grow threads and you'll see, you're gonna need more space, those kitty-litter tubs actually work pretty well for a single-plant DWC.
here's some pics from some other threads to inspire ya, and all credit goes to the original posters, these aren't from me. the link to MY pics is in my signature

bozo,
peace, love, dope
