Mounting carbon filter fan in grow tent

I have the attached grow tent and im thinking of buying the attached carbon filter. Does anyone know the best way to attached the filter to the tent? Ive read they are pretty heavy and the tent doesnt have much to attach to. There is a 4" hole in the top for exhaust but im confused as to how to hang the filter down into the tent. I appreciate you guys taking the time to help me out!

There should be cross bars that you can hang lights/fans/filters off of.

Yes there are def cross bars that ive been using to hang lights. So I hang the filter/fan from there and use a 4" exhaust tube to vent out the top?

Sounds about right.

Thanks man! Got my girls parents coming to stay with us in a few weeks and im sure it'll stink pretty good bythen if i dont have something set-up.

I would get a fan controller too then. Should help keep the noise down if you can run it at a lower speed.
