Okay ive got a 25CF grow space im working with and a lot of bends, think cool tube and NGB style cab so three separate areas. I want silence and the only thing more important than silence to me is odor control. The S&P silent series fan with the 5" flange seemed pretty sweet so i jumped on it. Its rated roughly 150 CFM on low and 200 CFM on high. Now i know its not a blower so it wont handle pressure as well but if i paired it with a 4"x12" phresh filter (rated 200 CFM) at the exhaust would i be good on both smell and sound you think? or should i have gone for a centrifugal fan? (loud as hell) any advice is appreciated! Also forgot to mention the light is a 250w HPS in a 6" cool tube.
The 4x12 Phresh is the match for a 200 cfm fan, so no problem there and the 200 cfm fan should cool the room, so no problem there either.
just realized that the static pressure for S&P mix vents is about half that of a inline centrifugal i can either buy the next size up and get a 6" or go with the flow and get a loud ass centrifugal fan and hope i can quiet it up!
I just got a TD-150S for my first grow. Hooked it up and it is AMAZINGLY quiet. Really, the only sound is the air itself moving. We put it back into the box it came in, cut holes on either end, filled the box with packing peanuts and now it really is truly silent. Using a Can Filter33 with it and everything seems to be working nicely so far. We'll see how it goes once we actually start growing of course
