Caput carbon filter?

I've got 24 small flowering plants in my 2x4x5' tent, and I have a 440cfm sucking air through an eBay 6" carbon filter, blowing through my tube, then exhausting.

The filter was purchased April 2k13.

Is it safe to assume that the filter is toast, when all I smell is cannabis throughout my entire apartment building?

I've never done it but I've read that you can throw the filter in the oven on a low setting for a couple hours to reactivate the carbon. If your filter is fucked and you've got nothing to lose give it a shot.

Thanks bro, I'll do a bit of research on this, and schedule it for my next harvest if the process is viable.

I need a reason to do a full shutdown anyways, as I need to scrub out my tent.

If it isn't viable and/or doesn't work, I'll buy a new one.

Any recommendations?

Cheers,

My filters tend to last at least a year...and veg room filter even longer. Buy some replacement carbon and change it. Possibly you need to add a filter too.

Ebay filter? Cmon mane!!! Get u a phresh or a phat filter.
It was for my very first indoor grow, so I bought the fan and filter as a combo for $200.

Thanks for the recommendations. I'll research those vendors.

Looking for other vendor recommendations too though.

Free three squares, a free place to sleep... not having to report to anyone for work... why avoid that? ;)

Oddly, I don't even use my own product. I just grow because I love the hobby.

I would not bother trying to re-activate the carbon. From what I have read it requires very high temps 350-600 C (above what the cleaning setting is on an oven) and it also requires a lot of airflow at the same time.

Hi Spek9,
Glad you didn't take my comment the wrong way...jokes about jail are in poor taste but I couldn't resist.

Hey, I totally relate to growing as a hobby...it's fascinating. I wanted to ask you where your filter output air is going? Is there a window you're pumping it out of, or a bathroom fan or what? Just thinking that that situation might be improved.

Yeah, that ain't happenin'.

So now this is fully a recommendation request.

Thanks,

No bad intentions taken at all :)

My flower tent is in what you could call a walk-in storage-type area, about 4x9', and I exhaust into that. Every day since I started indoors, I open the door to that room which is in the middle of my apartment so exhaust kind of expels to the external part of the apartment, and cool air is passively sucked in the same way. When I get up for work, I close the door for dark period.

I've never smelt it so bad before, so I know for fact up until the last few weeks, it was working ok.

My pre-filter is rather dirty, but I'm quite certain it isn't causing my issue, because the fan still causes massive negative vaccuum with fan at full, and even at 50% (where I normally have it). The smell doesn't dissipate when I crank the unit up to 440cfm.

Ya, if it worked before and doesn't now...def need new carbon or filter. I just use cheap Ebay canisters but stick new carbon in when odor becomes noticeable. Even a high buck filter needs the carbon refreshed periodically. Good luck man.
