chek your fan or blower, i doubt 2 were bad, you may need a larger blower.

good call, carbon for air filtration not water.

Could be blowing too hard as well.

I don't that would be an issue. it would just replace the co2 in the room at faster rate. It would use up the carbon faster. Not sure would have to do some research on it.

i'm not completely convinced about this. let me explain. I have a 265 cfm blower & a 6 X18 filter. If I run the blow unrestricted i can not smell any odor from the plants. At times with it being so cold in the garage if i run it unrestricted it will be too cold in the cabinet. So I made a carbboard circle that reduces the amount of flow thru the filter in turn the heat stays ups in the cabinet and the garage stinks alot.

You are running a fairly small blower - if you run yours restricted you are most likely not filtering the air every 3-5 minutes which is what is recommended. If you do not filter the air this often the smell will accumulate and leak from your enclosure. If you however hooked a 1200cfm fan to your filter you would be filtering the air in the enclosure very quickly but pushing through the small filter so rapidly that the air would not be filtered enough to strip the smell. If you ran a 4000cfm fan the filter would barely be stripping any of the scent but you would be filtering the air so often in both your enclosure and garage that you might take care of the smell.
I run a 440cfm fan through a 6"x18" filter and it works wonders.

i see kinda what u are saying, but if i restrict mine i add co2 not 2 worried about the 3-5 min air exchange.

There's your answer. Go get a speed controller to slow down your fan, seriously, do it.
By putting a piece of cardboard over a portion of the filter (which is how I've understood this post) then you're effectively creating a preferential channel for the air to pass through. The filter is designed to pull air in from all directions, for the entire surface area of the filter. When you change this, you change the dynamics of how it performs. At least that's how I understand it.

the cardboard is covering 75% of the intake on my exhaust fan. & yes a speed controller or rheostat would do the same thing.

Oh, I see. Then I haven't the foggiest, sorry.
Edit: wait, you mean like between the collar on the carbon filter (or the end of your ducting) and the fan intake? I can't claim to know this for certain, but that would seemingly change the way the air moves through the filter...

Is your fan used to cool lights and the room or just fresh air/odor control? Might consider putting the C02 and fan on opposing timers instead of constricting the flow with a DIY collar. Have the c02 run at night with fan off or switch back and fourth every several hours. If you are using an inline fan constricting flow while now lowering the rps can add excessive stress to the fan.

Plants don't use co2 at night.

Krebs cycle is just O2 based? How silly of me plants expunge C02 at night. Could still cycle during the day.

Just a random thought, but maybe it's a different strain this go-round that just reeks more maybe? =)

yes , i understand it it causes more stress on the fan, but it worked. Here some bud shots. And what i am talking about. I agree a rheostat would be better. 3 master kush almost done 1 600 watt hps.View attachment 1441904View attachment 1441909View attachment 1441908
