Use a standard wall type central AC/heating grill, cut a cardboard box in half, mount to the grill on the inside of the grow space covering the grill, cut one of the sides of the box out (not top, bottom or front), add a cardboard extension to the hole/opening.Wonderon said:
Something like that...
Don't get fooled by under-rated cfm values for Elicent, these are the quietest fans for the static pressure around. This is the force of air, the value often overlooked you must pay attention to. Compare the 6" from both and Elicent wins hands down. If you only look at cfm a cheap Dayton squirrel-cage appears to be the best value but in practical use not so.

I'm a little worried that the 6" elicent isn't gonna be enough but the noise issue might make the choice for me. Would 309cfm be enough to clear a 4'x4' room assuming I run a can50 still? I def want to avoid as much noise as possible. I hear these things are louder then on would expect so I'm a little worried lol, not quite sure what to expect as I've never had to used one before. Thanks

The Elicent should be OK if your passive intake is not restrictive reducing it's effectiveness. With the Elicent you'll get an air exchange about every 60 seconds which should be adequate to take care of the heat generated by that 1000. The basic rule of thumb is exchange the air in a room in at least 2 minutes...that works great if your hoods are being cooled on a separate circuit/fan as the main issue is heat...especially in the summer. Exchanging air every 60 seconds and using the incoming air into that space for cooling also will work but I think important to use an air cooled hood drawing air from inside the room to help direct heat out. You can also use double foil covered bubble plastic insulating stuff you can find in any hardware store. Use two layers and make a blanket for your hood. It really helps to retain heat inside the hood as opposed to it radiating out into the grow space. In the winter you may find a need to remove the insulation. I assume you're planning on an 8' ceiling in that 4 x 4 space? Just don't place the intake of the cooled hood right next to the passive intake for the room. Design things so the incoming fresh air flows across the room then out the intake vent on the hood.
One of the things that will help fan noise is hang it with bungee cords and do not mount directly to a wall or support cause a decent portion of what you hear going through walls is vibration or low frequency stuff being transmitted through. Insulated ducting helps reduce noise but not very flexible and good for longer runs. Duct mufflers work. One time I made a duct muffler mounted on top of a cardboard box filled with acoustic foam inside a closet for the grow in the basement. The muffler was mounted in one corner and the intake in the other corner...air flowed without restriction but the sound had to bounce around inside the box...which was muffled by the foam.
In some ways the 6" Vortex's I ran were louder than the 12" Elicent exhaust I had. It's a different kind of noise...hard to explain. I ran my 12" Elicent and 6" Vortex fans open and the Elicent was whooshing while the Vortex was howling.
Lot's of little tricks to make it all work...you'll figure it out.

^^ this is an awesome post, whatever. so your a preference is elicent? interesting about your comparison from the whooshing to the howling. my 12" vortex is a monster, residential use is not recommended.
thats a shame quiet is such a big requirement.
with a bit of noise this monster can-max will move all the air you ever need.

Yes I prefer Elicent and usually go with Vortex only in the smaller sizes of 4" and 6" and has mainly to due with noise generation. 8" and 10" Elicents are in the same size housing except the 10 obviously has a larger inlet/outlet. The 10" Elicent makes that unnatural noise like a howl or jet engine.mikecar312 said:
I don't know why the issue using a 12" Elicent in a residential setup. Helped a friend and we put one in the attic, had about a 18' run from the exhaust right to the attic vent. It was right above the bedroom and the Can 150 was in the closet behind a small sheetrock enclosure with the grow room in the basement. When running the only noise you heard was in the bedroom at night mainly from the enclosure and not loud at all. There was more noise generated with the 6" Vortex I hooked up to muffler/box setup in the same closet, with the fan being in the basement, and that was really just air moving through the muffler opening and nothing you can do about that...except maybe use oversized ducting/mufflers to prevent all that air getting squeezed through a small opening.
EDIT...one thing I want to clarify is the cardboard box I mentioned above was LINED and not FILLED with acoustic foam. The Vortex was like 6' below the muffler opening and could only hear the air moving and not that howl. In retrospect shoulda created an 8" muffler.

Vortex =cheaper, More airflow, Longer warranty, Fairly quiet fans, What more can one want!
