Ventilation info. cfms needed per cubic feet?

[LadyLiberty]

CFM: cubic feet per minute.
Divide total cfms by the LxWxH(cubic feet) then you have how many times your fans are flushing your cab per minute. or at least supposed to.


question is how many times should someone be flushing or completely replacing the air in their cabs? specifically HID grows.

sorry to be anal but im looking for a response along the lines of

i have a blank type light and my cab is blank feet by blank by blank high, and i use blank-ity-blank fans which seem to keep my temps around blah blah and my plants seem to like it! thnks


best regards,

i have 2 x 600 watt HPS lights in air cooled reflectors and my tent is approx. 32 inches by 59 inches x 78 inches high, and i use a 449 cfm vortex fan for exhaust through a carbon filter which seem to keep my temps around 75-80 and my plants seem to like it! thnks

I use 2 x Honeywell Turbo fans as intakes into the tent. temps in my tent really depend on the ambient air temp outside of the tent.
