Can I exhuast my cabs ventilation into a wall?

[Jnugg]

Spring/Summer is here and it gets damn hot in the Southeast and for the past two years I've had to deal with exhuasting my cab right back into my bedroom and keeping my central A/C cranked and I can no longer afford to do that.

I have an attic entrance in my bedroom that I suppose I could exhuast through but I really don't want to as I live in a one story apartmetn complex and there are no dividing walls up in the attic sepperating each unit so I would assume the sound of the rushing air could/would be heard especially if a cable man or phone repairman was in the attic for another tennant..so I was thinking about exhuasting into one of my bedroom walls....can this be done,how much clearence should there be from the exit of the exhuast duct to theother side of the wall?

Hello Jnugg san,

I would not do that as that would cause that wall to grow vast quantities of mold. You don't want this. Mold can be a health hazard.

Does this room have windows? You could run some ducting on 30 degree angle upwards towards the base of the open window. Do you understand? Nobody see from level of window, and even a little bit higher.

i don't know about the mold being blown into the walls because your just exhausting hot air and not hot moist air into the walls...but i wouldn't attempt blowing it into the attic for the security reasons mentioned before...ya probably want more than just a few inches from exaust to the wall cause your gonna "hear" that air flowing if your fan is strong enough...maybe run a 90 degree angle into the wall and shoot it straight up would help with the noise...good luck and stay safe

Good point about the mold...Obviously the air has moisture to it as there is a grow going on inside the cab that's being exhuasted/ventilated and to be honest these places are old and there is mold behind some walls already (discovered that when my soap dish in the shower fell off!)!!

No can do with the window either.My landlord is here everyday just about to do work in his office a few hours out of the morning and afternoon plus my window is not a jealousy window (crank window) it slides up to open and you must prop it up or else it falls down and the land lord won't fix that and I would if I weren't under verbal lease.

Do you have any other suggestions as to what I can do?I only have a 4" 172 cfm eco plus inline for exhuast and my grow is setup like so... Bedroom<exhuast side of fan ducting<exhuast/inline fan<intake side of inline fan ducting<A/C hood<400 watt HPS<Grow cab<Passive intakes<cool air from central A/C being pumped into bedroom (cold air falls so my passives are done Maliboo or original C-13 style with 4 2" I.D. PVC tubes with 90 degree bends for light traps).

I need every bit of that inline fans CFM so I can't use a solid state speed controler to quiet,slow the fan down and I can't afford a 6" 449 cfm vortex with solid state controller for $180 or even better (becuase you can run it slower and still get an asston of air moving) 8" 747 cfm Vortex Inline with solid state controler for only $224.10 for like atleast 2 more months and it will be damn hotter by then!!

Do you think If I got some 6" ducting on the exhuast side of the fan it would quiet the wooshing sound of the air noticebly..what about 8" ducting or maybe a longer run of as straight as possible 4" ducting and then into the attic with maybe a box over the wood entrance panel covering the hole going into the attic?


I'll get up there and take some pics for you guys later on today.
