A question for someone who have experience with growing on pc case

[GrowForLife]

Hi,
My question is about the light that comes inside the grow box from the fans
In the flowering period, it's important that the plants will be in a total dark, right?
So how do you do that?
Maybe it's not necassery to do something about it?
Thanks

Do they make 2" ducting?

What do you mean?
I just want to know what people generally do,
if they block this light (that comes inside the grow box through the fans)
And if so, how do they block it?

My exhaust fans go through a DIY carbon filter while my intake has a light trap on it.
