CFM requirements

So I'm gonna have 2 4x8x6.5 grow tents. each is gonna have 3 hoods either 3 6s or 1 600 1 400 1 600.

haven't decided.. add input for that. they will be air cooled hoods.. not sure weather to leave the glass on or off either.

what size fan would I need? 6inch 440 cfm be fine? how many would I need per tent? they're gonna run straight all at same fixed height.. fro. left to right..

yea i thought someone would have replied but its easy to google ur answer.
A good quality 6" fan with speed controller would be fine @ 440CFM
Also go with 3 600's for flower & keep the 400 for vegging
