I'm trying to find some fans to cover my MASSIVE grow space. The math for finding the CFM i need is freaking me out though. Can someone double check me?
Here are the dimensions of my massive space:
WxHxD
16"x18"x8" (inches)
So in order to get the cubic feet, i divide all my dimensions by 12 and then multiply them together?
(16/12)x(18/12)x(8/12)
i get ~1.4^3
So at a minimum I only need a fan to cover 1.5CFM? A 60mm fan @12CFM would clear the space 8 times per minute?
What am I missing? Why do i feel like i need more fans?
