venting question......

Hi, I have 10 plants under 1000 watter under a tent. The tent is in a room. I am not venting outside the house, but instead venting out to the room. The room is much cooler and has fresh air.



My tent is 7x5 ft, I am planning on using 6 inch 440 CFM carbon fliter exhaust fan combo.


My question is what size air intake should i get?



thanks

i would go with a six inch

if its a passive intake 6 inch, you could go smaller with a fan on the intake
