Fan Question

[outdoorsman101]

If one fan is blowing air in 150 CFM, should the other fan blowing air out be 150 CFM? will my small grow box explode if i dont (sarcasm)... but really, should they match?

If you have one fan evacuating the air from your space, than you dont need a fan to add air in. Just cut some holes in the other side & as the air is being evacuated fresh air will replace it from the holes.
