Carbon filter help 24x22x8

Hello all. My room is 24x22x8. Just wondering can someone tell me the proper number of carbon filters I would need to not smell anything? Would 4 12" 1700cfm filters do the job? I also have 12 1000w lights. No co2 . 36k btu ac mini split and 9 oscillating fans.

Circulate air 2 times per min. So your room is 4750 cu ft. So three would work. Replace every 2-3 grows, mine stop working good after 6 months, then again full flowers hard to cover up. After wk 6 I scrub adjacent room and use ona.

You ac will not be big enough. I have 12 lights and 36000 just like you but I run them full power in winter, but 75% in summer. I'm in a basement in cooler climate. Hopefully some of your ballast are adjustable. Also co2 allows you to have a much warmer room...

Thanks for the help...

Any more questions or problems feel free to message me

I would over size the filters. You will get longer life out of them.

I also order the same carbon phresh uses and refill mine.

I replace the inner synthetic liner with metal window screen and then you can spray them out with a hose and bake for a few hours on 500 degrees.

People say it doesn't work but I know it does. Its documented in my thread.

It stinks. I put an old stove in my shed to do it. You can save the old carbon and put in turkey pans an inch thick and bake to reuse.

Wawa wait slow down buddy did you just say you reuse all your carbon and bake your filters on 500 in an oven?

The police have been with in 100 yards of my grow room exhaust twice in the last couple months.

Why don't you read up on it a little bit. Labs reuse carbon.

Here is one taken apart. You see the aluminium window screen? That's so I can bake it.


That's a 16 pound bag of carbon from a hydro shop.

Here is one I just took a part. I was fixing to bake the carbon.

Now, you can claim it doesn't work. Out of the two of us I'm the one that has done it. I know it works.

All carbon does is absorb volatile organic compounds. Baking them burns the VOC off the carbon.

One more thing. I don't go randomly talking out my ass. I'll back anything I claim up.

It does smell god awful. Its the reason I put an old stove in my shed.

before I started venting out the window i rotated 2 carbon filters, and while one filter was in my grow room,, the other filter was getting serviced , taken apart and the carbon baked re assembled and ends taped so no air leaks around carbon at the ends

Yes I did say that. It works.

I know everyone is not comfortable baking the carbon.

At the least people should buy the replacement carbon. Its a hell of a lot cheaper.

No fancy machines needed. That's a lie to. If you use a vibrating table to pack the carbon it can actually cause failure. What happens is all the smaller pieces end up on one end of the filter and will quit scrubbing first.

Hand packing avoids that. You smack them and tap it on tap it on the table as you fill. Over fill so when you press the cover on it will be tight.
