What Do You Think?

How does my grow room look to you? i am using two 1000w Mh set-ups and i have three fans, two for intake and exaust and one for oscilation. i painted the floor white and covered the wall with that reflective white plastic they sell at hydroponic stores. i have two windows (one in the back door, door blocked off) covered in two layers of screening. i plan on covering up the windows and adding ventalation tubing through the room and to the lights. the whole room is insulated as well as door and is outside by its self. tell me how you think i can improve it or fix any errors. thanks the last pic is what i plan on doing.

Looks good.
You might want a some kinda Co2 source and a sulphur burner.
What are using for nutrients ?

hell ya ,"but how much is your electricity bill

Wow that is gonna be good !

thats nice

Looks good, man, should be a nice-producing little room there! Gonna use HPS conversion bulbs during flowering? I'd use one if I were you, and switch which reflector it's in every week, give the plants a nice spread of light spectrum that way.

Where is your exhaust fan going to be along that ducting? At the bottom or at the top?
