The bad thing is some people probably don't know what bandwidth is such a shame

I have never used a 400HPS but I love the bud density of my 600. I have a 434CFM pulling through a 210cfm rated Carbon filter, room size is 4.6'x5.7'x7.9'

Will be upgrading to a larger weight carbon filter. My LA's are over powering it right now.
