Anyone have a clever idea to use MH lighting in a 10" canopy? I am only running 4 x 160 VHO currently on my 210. I really want to add a couple clams but with my 30" depth and ony having 10" for a canopy have kept me from doing it. Its gotta be retro in the canopy thats the catch. Currently there are 4 4" fans 1 on each side pushing and 2 on the back pulling and even the VHO's get warmed up pretty good.
