WTF is this mickey mouse sh*t?!?!

So whats shakin people? had to put up a crazy name to get some veiws, anyway, I just moved to a new spot where my garage is completely uderground, and I decided to put a good use to this shed I have been hanging on to thats not even constructed yet ( pre fab)

its measurements are 8x10, but Im going to scale it down to 8x6 Im rocking two 400w hps cool tubes for flower, and either a 175 MH or 8 tube t5 fixture for veg. I need some ideas so people help me out.

I would get 2 1000's in that or maybe 1000 for half and a 2-400's for the veg room. just my 2 cents. why cut it down anyways? I got a small 3x5 area for boom and it has a 1000 easy to pull over a lb in there.
