it only has to be connected to tubing and a carbon filter to de-odorize it.. but if odor is no issue no tube is needed but you will need to correct the light leak somehow.. so im guessing tubing is ur best bet..

lights- well your area is roughly a square foot.. so about 2 or 3 30 watt daylight cfl's for veg.. which is like 4000-6000 lumens.. running @ 6500 k
(WALMART)
and 2 or 3 42 watt soft or warm cfl's for flowering.. runninng @ 2700 k
(Also WALMART) just read the packages of the bulbs it should say it on them...
