I've spent the past 2 hours trying to wrap my head around working out extraction.
Assuming the height of your tent is 2m (?? you didn't say, need that number to be accurate) then to exchange the air every 3 minutes with that many lights and assuming you are using a carbon filter then you will need a fan/multiple fans that can run at 6480m3/h.
The formula i used to work this out is LxWxH = cubic volume of the tent. Which with yours that comes to 162m3. To achieve replacing that amount of air every 3 minutes you need to multiply the volume by 20, which will give you 3240m3. Supposedly you should add 15% for every extra 600w light you use and 20% for a carbon filter so i just doubled that number to get 6280m3. I could be wrong about having to increase it by that much but either way, 1170m3/h is just nowhere near enough i'm afraid.
