super closet

I recieved a super closet from a friend who was being transfered out of town and couldnt take it. he paid $3,300. 4 this thing and I think it sucks. it came with a 430 HID, 2 - 20 gal reservoirs, co2 injection ,timers, fans etc. I have a crop in it now and its on its final 2 weeks. The plants are looking ok but you cant close the doors ( thank god i have a room 4 it. ) because it gets so hot . It also has light leakage every where. My friend said thats the way it was when they got it. Does anyone know anything about these things? I also have it properly ventilated.
