ok, i have read to many debates on this and i need somebody to please clarify something for me ,
in 1 of my grow areas, i can only run 1 intake/outake ruck fan with ducting,
i want to have passive air in or air out holes,
is it more important to have fresh air coming in , or old air exhausting out ?
i have an intake and exhaust in my main grow op , any help on this would be welcomed !!!
thanks in advance........
