heres the inline fan with carbon scrubber in the attic...

not worried about light leaks its in a walk in closet...

let me know what you think? i got the temps down finally to 82-85 degree lights on 24/0

no plexiglass to create cool tube effect on reflector either...that will come soon..

the 4"inline is making it hard to blow weed smoke out my window, sucks it back in

2nd pic is looking through an old exhaust hole that was taped up...

as you can see exhaust goes straight out the top
