it's only 600ft elevation here but we're in a river valley and all our weather and air comes straight down the mountains around us....I swear by all that is worthy that the fresh air flowing through my flower room makes a huge difference in taste and potency....i have a 170cfm inline for intake, with a carbon filter, and a little larger inline with a filter sucking the old air out through my hoods.....makes for some fine flowers I'm here to tell you.
