:doh:it did say 2 min, and i probably even read it in one of your comments.
i had no idea that exhaust is only run with lights on...
yes, mine is connected to the filter. the air goes through the filter, then through the lamps and fan is pulling it out. Everything is connected with ducting..
so i need to set up a timer on the fan, right?
my six inch fan pulls 452 CFM. the dial goes from 1-10, im assuming CF change when i switch the dial...
that_girl said:thanks , Auburn. if the air is constantly being pulled out how does it work with CO2? it's suppose to be a certain ppm, right? I never had a burner , want to add it to the next cycle.

The only reason to exchange air at night is temp/rh control.
