All you need to think about is how the mismatched blowers are actually working at counter purposes to each other. LOTS of active exhaust CFMs and a passive intake are actually MORE efficient use of your air-moving watt allotment.
Sorry to threadjack, but I have a 172cfm exhaust and a 80cfm ductbooster active intake, piped around the plants with holes cut in, along with the end capped. I also have a 6x8 passive intake on the front left lower corner, I just wanted to get fresh air over closer to the plants. Do you think this is a problem, or due to the ample sized passive slot ok to do? seems to be working good now! Oh, and to the original poster...very nice work. I have a similar setup, but used rigid foamboard in lieu of wood, in case it needs to come down in a HURRY! :smokin:
