that looks like the exact same stuff I'm using, EXCEPT, mine is a 6" diameter system, and my fan is 250cfm ... the bad news: it ain't enough in my 2'x4'x7' 400-watt cabinet ... I'm also running a separate exhaust fan, plus an oscillating fan inside, temps are still in the high 80s, low 90s, at the canopy ... still producing great buds, though ... :smokin:
