Seriously get your 600 with a good vent fan. and get yourself some good soil. i was a hydro guy at first i did it all ebb n flow, dwc, aeroponics. Sure you can push your yeild but it doesnt taste the same. nor do you get the amazing pink n yellow hues in the plants final stages...%99 of the plants you see in skunk or high times are all pure organic plants. Get a light, get rid of the coco shit, n start of simple. It looks like your a begginer, dont take offense to it everyone is at some point. But those who admit they dont know, learn and ask are the ones who one day are able to mentor.
