Re: how to calculate air flow..
If it is your only fan, I would suggest keeping it on all the time. You want a good fresh air exchange in your tent (unless your using CO2) in which then you will have the fan set to OFF when CO2 is being released. Without good air exchange and airflow, you may develop molds and other problems later.
I have 2 fans in my tent, with carbon scrubbers, one stays on 24/7 and then other comes on only with the lights.

Re: How to calculate air flow..
you need to know how much cubic meter (have 2 convert) the room is and how many watts you are running , on the hand of that you look for a vent that matches ,dont know if this makes any sense because off the convertion but this is how i do it .

I keep my fan running 24/7 for good air exchange.
My ambient humidity is normal around 50% with fan running and have noticed with lights off/fan off night time humidity can rise very high this may lead to mold problems/bud rot.
