Im going to be running a grow box with a cloner room veg room and a flowering room. Total square foot is 9ft. I will probably have 4 cfls between the veg room and the clone room,and a 150watt HPS for the flowering room. My question is will 2x 80cfm inline fans(1 for intake,1 for exhaust) be good enough for ventillation, or will i need 2x 250 cfm inline fans?

it will be good enough
