Depends entirely upon your ventilation requirement, Co2 injection, ambient temps, intake air temp, duct run lengths, carbon filter restrictions and lighting wattage.
150mm fans IMO you can't get better than SYSTEMAIR RVK's.
But for example I use a 150mm in my 3.2ftx7ftx8ft room with a single 400w.
For example.
Your room is 5.65m3.
X60 is 345.60m3/h of fan power.
However this is just for air exchange once per minute.
20% added for carbon filter.
5% added for air cooled hood.
15% added for non air cooled hood.
20% added for ducting runs.
Every 90 bend in duct work reduces your fans efficiency by as much as 20%.
There are a lot of factors that go into fan size besides calculating your room dimensions.
