bathtub set-up help

[speekergeek]

Hi everyone, I am setting up a nice little room for my babies in my bathtub, I hung some black 4 mil plastic from the top down to make it light proof. It is an area about 2 feet wide, 4 feet long, and 7 feet high. Using a 400W HPS to light the area. I put a fan in there and it keeps pushing around the "curtains"! not good. how hard does the fan have to blow? this one is a small 9" fan that really kicks some ass. any suggestions? just wish i had sliding glass.... I am planning to cover the black plastic with reflective mylar or white plastic. thanks for any help. heres some pics of my current ladies, enjoy.
