Hi Everyone, I have an issue and was wondering if someone could help me with some info that is related to this original post and about carbon filter and odor.

I have a 4 x 4 x 7.5' tall, home built, grow box using superior material. It has no light or air leaks. I'm proudof this set-up as it is doing so well.

I am going to add 2 feet to the length of it to make it 4' wide x 6' long and 7.5' tall in the end which may make a difference in the answer to this question.

Right now it is 4' x 4' x 7.5' and I have a 4" hydrofarm inline centrifuge exaust fan that leads to a carbon filter on the outside of the box. The inlet is a 4" hole with a new reinforced hose ran to just under my window for fresh air(this works very well). It had no smell at all for the last 2 months and now its starting to smell(not because its ready to flip to 12/12 either). It's still in vegetation and hasnt started to smell any different than before, a good semi-strong smell. Now that there is some problem somewhere, there is enough to smell what it is throughout the house, subtle but its smelling it up. Why? I bought some new 4 inch reinforced hose instead of just aluminum that I was using in case there were a few small holes(cats, although I couldnt see light leaks but even a tiny hole over a few hours could stink up a home). That didnt fix it either. I was told that if you push too much through the carbon filter then it wont be able to filter all the smell out(basically overworking it) and it will push some smell past the charcoal filter anyway. I am trying to figure this out. I am more than likely going to just exaust everything right outside my house that I bought but I dont know if I should still use the carbon filter if I do that(another question) if someone knows how to do this.

Any suggestions for my problems? Do I need to change the filter at all. I read that the charcoal lasts for 1 year and the hoses are fine with no holes(no cats anymore anyway, thank God, old roomates). I think that my problem is that the inline bloere exaust is pushing too much air through the filter at a time. I am thinking of going to buy a regulating timer for when the temp gets up to 80*F it kicks the exaust on until it cools it to around 68*F ? (Maybe somewhere in there, not sure on the temps really yet) Another question if someone knows that one. That would serve 2 fold purposes, well 3 really. It would, maybe & hopefully, get my odor control handled. It would quiet down the fan, I wouldnt hear it as much and I might save a little electricity unless it spikes when it turns on(the centrifuge fan). Thats 3 benefits there already :) .

I am going to extend the length 2 feet today making it a 4' x 6' x 7.5' tall as the plants need the space(not sexed yet). Maybe this will help with the amount of air pushing through the filter, maybe not. Maybe its just a lame filter but it worked fine before. Now it's stinking. I cant wait to get out of this little cabin and in to a nice home that I just bought. I cant wait.

Please HELP!!!!!! I really don't know what to do with this issue except what I have done. I thought the cats had to have punched a couple holes into the old aluminum hose which would have solved my problem but I gotta keep trying, huh?

Anybody have this issue before? Am I pushing too much air with the 4" inline exaust fan for the small area? What am I to do? If I just exaust outside, it will put out a white cloud of moisture because I live in Alaska and 80*F going out to 0*F makes a big, smelly, white, exausted moisture cloud. I don't know at this point. I'm kinda stuck. I hope that useing a timer for the temperature to turn on and off when it reaches the right levels and that adding the extra 2 feet helps as well. Right now that amount of add on to the set up will give me 1/3rd more space then I have now. I will switch to a 600 Watt MH from my 400 Watt bulb now also because of the increase in size. I have 3 supplemental T-5 lights on the sides and a couple of the Aerogro 32 Watt bulbs going all for under canopy when its ready.

Any and all help is appreciated. I'm not a know it all. Please help if you for sure know how I can handle this or fix and try to perfect my set-up. Thank you all in advance. Also please help even if your guessing and think something will work, Thanks Fam. Peace J

ONE WORLD- ONE LOVE. PEACE Captain J

lets me get this straight...your blowing your hot smelly air into a carbon can outside your grow??? wrong way round mate.....the carbon goes into the tent/area and the air gets sucked thru and into the can, down the ducting , thru the fan, out the ducting and then exhausts into the atmosphere....preferably up a chimney or out a window, your reducing the power of your fan by 'muffling' it mate. switch it round.

like dura said you should be pulling thru the carbon filter. and make sure there is absolutely no leaks in your ventilation. and this could be some bullshit the hydro guy told me , but he said putting a dimmer switch on a fan without one is a bad thing.
