Ever make a cut into your grow tent?

I just bought a filter/ventilation system for my existing grow tent.

The places where the premade ports are don’t line up with where i want to enter the tent and orient the hose and filter.

Ever cut you a new hole for such a purpose? I’m toying with the idea and would synch the gaps around it to make it relatively air tight.

But before I did that, wanted to check with experienced indoor growers who may have done this for the ins and outs

never cut the tent before, I just used the flexible duct stuff to bend my way to the existing premade hole…
