6" 320cfm is plenty good for a typical sized tent or room. As far as making it quieter, it gets much quieter when you have it ducted and running for some reason. With no ducting attached it sounds like I'm about to achieve lift-off. Whisper quiet with the ducting on though
Have you actually installed it yet?
No i havent installed it yet .....but i have a another grow going on with a 4" and its real load even with the ducting on it......I know that 6" is ok for my size tent but im not sure that its will be ok with a scubbr hood and ducting all doing everything with one fan.....most people seems they have two fans one for exhaust and one for hoods.......someone told me that if im not going to use TWO fans that i should get an 8" fan because ill be doing the work of two fans with one fan........also i was told that going with bigger fan will be more silent because i can get a speed control and lower the RPM to what a normal 6" fan would run......i dont really want to do this becasue i already have a 6" and those elicent fans are SOOOOOO exspensive!!6" 320cfm is plenty good for a typical sized tent or room.

What are the specs on your interior fan and scrubber? Didnt you say you use a small pc fan? or was that someone else? Also, Instead of 2 fans, can't I use one fan w. multliple ducts going into it and use a damper system to shut off the exhaust to the chamber when running CO2 ? or maybe this will make more noise?You can have all your exhaust fans and regular fans turn off when the Co2 is on...but if you want to have optimum Co2 levels it is better to not exhaust anything from the room at all..that is why I prefer to run two fans.....even though the noise is kinda annoying.....but I have speakers set up in my veg and flowering areas so I just bump my music and drown it out
Yeah it just recirculates..I have reconfigured my exhaust almost every way possible and this is the best way I have found as far as smell goes...
For a sealed tent, you use two fans because:
I use a 6 inch 270 cfm can fan for cooling 1 1000 watt and 1 400 watt light....and a 170 cfm eco plus inline fan for circulating the air...I have no experience with a damper system ...but if noise is what you are trying to avoid I seen people enclose their fans in a box to reduce noise......I think I saw it somewhere in this site if not mistaken....and the noise don't bother me 1 bit..I always have music on and speakers in all my rooms so.....
My question still the same WHY do you RE-CIRCULATE the air back inside? wont that make tent temp higher than if exhausted out of tent??????
Two types of systems here. Closed loop and open loop. Closed loop is recirculating the air and you're providing the Co2. This is benificial becuase you can pump the Co2 and max yield. Open loop brings in fresh air and exhausts to fresh air. No Co2 is required. Both have their benifits.
In an ideal world ... you would recirculate back into the tent but you would have an Ice Box attached to the air outlet. The HOT air is in the hoods, and being taken care of seperately. So if the air isn't that hot to begin with, you only need a little water chiller to keep temps under control.
You can recirc the air ONLY with a good Co2 and total environment control system going. If you can't provide Co2 and cooling, you're FAR better off bringing in fresh air. I use a Can66 and a 8" Elicient inline for my primary exhaust (to fresh air). I have an open loop system.
Actually exhausting the air from the tent through the scrubber and the hood make the tent hotter because the light produces heat...where is the heat trapped in... the tent......so then that warm air is sucked through the scrubber and hood kinda defeating the purpose of a cool hood,don't get me wrong it will run cooler than if you had no cool hood but getting the cold air from outside cools the hood and light much more efficiently......so producing less heat from the source in the first place.....if you still have heat issues with a cool hood with good set up then you would need to invest in a/c or ice box and water chillers..
Yes i get that 2 fans are better than one and that pulling cool air from outsite the tent souly for the lights is great becasue it cools the lights more efficiently and it dosnt need to be filtered on its way out......the ONLY reason i want to use 1 fan is because of noise reasons in an apartment that i share with my gf.... Its 2bedroom and this tent will get its own room. I dont want (gf dosent want really) to hear it from anywhere else in the apartment .....I plann on covering everthing in foam or insualting or making a box to do what ever i have to do to make that room silent and keep temps in 70's......So im starting with one 6" 320cfm fan and im going to see what my temp will be using it full blast as follows: filter>duct>hood>duct>fan>duct>outside tent but still in room becasue i cant have ducting exhausting into the rest of the aprtment becasue the door will stay shut. I dont want to have ducting hanging out the window or even up against the screen.....people walking by would say hey look that person has a duct exhaust ending right there at his window...thats no good. Also no attic access from the spare room and gf is not giving up master closet for my grow.. so im left with just exhausting the air into the room.....Yes i know this is a problem on many levels one for temp reasons and another for fresh air reason....mabye theres a was to still use the window for exhaust but HIDE it some how ..i dont know.
First, you may need some extra equipment to pull it off succesfully. Is this a window you can put an AC in? Can you bring in a 55gal reservior and a chiller? Can you lug Co2 bottles or propane bottles into your home every couple week? Is there ANY way you can possibly cut some holes in the ceiling (inside the closet) to vent the light heat?
I cant afford a 10,000w btu air conditioner and im not sure i would be alowed to put it in anyways and dont those things use alot of energy and are loud...i diff cant start cutting any hole in the celling if i want my deposet back...what would i do with a 55 gal bucket? and chiller? are you talking about setting up some water cooled light system? wont i need pumps and hoses wont that cost alot too....i mean im not cheap win it comes to my set up but i have to work within reason......
Holes in the ceiling are nothing. They can be repaired in an hour with a can of spackle and some spray-on texture. Evereyone knows a handyman or three.
Well you got balls growing in an apartment complex my friend......I couldn't do it........but enclosing your fan will reduce noise and you can go to home depot buy you some wood make a frame to fit over the window make a cover for the frame out of wood or panda film or painters plastic(with panda film or black or white painters plastic it is much easier to cut a hole for the adapter than cutting a whole in wood)....get a duct adapter screw it on the wood frame...you keep your blinds on the window place the frame over the window and everything looks normal from outside..you simply keep the window cracked so the air has somewhere to go....I have this type of set up on my window...
yea that sound like a good idea...do you have a pic of it?? id love to have an image to go with that......
