lightproofing, need help !!

[bombdiggity]

Hey I have the inside of my grow cab lined with black/white film with lips covering the seems of the doors, and my intake is a pvc elbow facing the rear of my box. Only problem is that I have my exhaust fan mounted on my box with a hole cut to fit, and I have no idea how to light proof it. Any suggestions would be awesome, and greatly appreciated :)

I use a short length of flexible ducting.

So i just mount the duct to the outisde of the box over the hole? Do I like turn it in multiple angles or something, and isnt this going to reduce my airflow?

Thanks

Yes, yes and yes but not enough to worry about unless you put a kink in it.

I hide my ducting by cutting part of the bottom and back out of a cardboard box and sitting it over the duct, it just looks like a storage box.
