just found a post regarding your dwc grow sorry not replied sooner but have red through al your thred and if this is your first grow then congratulations so far so good by the looks of things, saying that i am no expert, but i no a man that has grown like this for years look at his thred and profile his online name is rosman and also check out stealth hydroponics.com they will have a few little gadgets you can make your own style eh, but i agree that you should put some white sheeting instead of black and if you got the extra cash then get the dimaond reflective even better plus its fire retardent so all to the good, my only surgestion would be to use the scrog meathod with your plants especially with the space you got, there is some good info on this meathod in the grow facts hope the link works
GROWFAQ
also try this link for all your grow infomation found a pdf file with the growers bible which is free

plus that will give you some good info on your potential outdoor grow you mentioned
the only thing i would say to ya would be make it simple and not to tech less to go wrong, cause i did that, but like you said you can mess with your laidies loads and they keep on growing eh haha
