Attached is a very 6th grade drawing of my stealth cabinet I am building. But, I have a few questions. #1 being, if I add an out-take fan in which shoots the "Stinky" inside air into a carbon filter, does it filter it and spit it back out into my cabinet? And if not what would if i to do, run more duct work into the box? Is it a good idea to have a intake fan which the ducting connects to, to keep the air circulation through the cabinet, and add another intake fan to blow in fresh air to convert? Just a couple of noob questions. This is my first cabinet grow.

I have my carbon filter on the inside of my cabinet with a fan sucking thru it, to the outside.

How big is your cabinet ?

Is this the easy way to do it? I'm asking cause I've never done a cabinet grow, always DWC. So I'm not sure where the Carbon filter goes. Inside, outside, etc etc. I don't know lol. I know it's purpose is to clean the air correct? So therefore, why couldn't I just recycle the air that it cleans, but in the meantime steadily blow in outside air that constantly gets cleaned and recycled also?

I wouldn't do it that way cause basically that would be recycling your air and it needs a steady supply of fresh air from outside the box.

here how mine goes


Exhaust <- FAN <- Ducting <- Air Cool Hood <- Ducting <- Carbon Filter

They make some small ones, I would start checking them out and see how (or if) they would fit into your design and area.

Ok, golddog so Exhaust I take it as, would be what's coming OUT of the box, into the FAN, through the ducting, into the air cool hood, ducting the carbon filter? Like I said, I am a noob to the cabinet ordeal. I thought it could be just, fan, ducting, then into carbon filter, which blows the air out. Fan -> ducting------> Carbon Filter ----> ducting-------> Fan---------> outside? Correct?

This is how I have my carbon / fan setup


And the other fan draws air from the hood of my light to reduce cabinet temps, they both exhaust to a hard pipe the shoots out my roof

Wow curtiss!! Man, nice work! Ok, what if my hood is already cooled with a fan? Would I still have to run one to draw air from it? And also, as I am understanding all of this piece by piece. I would run a fan blowing out the air into the carbon filter, which then in return shoots that air into the room. And then install a intake fan, to circulate fresh air through? Is that correct?

Check out his picture, I didn't have one of my set-up and it's night time for the ladies.

You will see the Filter, no ducting to it. It sucks the air from the enclosure.

So most people have passive air inlets or fan power inlets.

Anyone have a picture for this gentleman ?

Right, so take a 6" inlet fan, run ducting out of my enclosure into the fan then out to the filter? But could I still run a fan to bring in fresh air from the room? To circulate the air in my cab?

Yes remove as much heat from the cabinet as you can, run your lights at night if possible, I have mine start @ 9pm and turn off @ 9 am the garage temps are in the mid 60's and the cabinet gets into the mid to upper 70's with a 165 & 180 cfm fan being used for the air and hood

And pull the air threw the carbon filter and then have it exhaust from the cabinet & get a y split to remove the heat from your lights hood

Good luck

Yes you need a different hole towards the bottom of the cabinet if possible for the intake and the exhaust at the top since heat rises

Ok, I see now. I found a picture showing cooltubes and how theres an intake blower at the bottom, then an exhaust blower blowing straight into a carbon filter. And a cooltube blower blowing over the lights. I see how I want to do it. I'm going to use a 150 Watt HPS, I might switch to MH for vegging. Therefore, can't I just run some ducting above, or mounted onto the hoods constantly blowing air on them? And the room I'll have them is Air conditioned 24hrs a day. So the temp will be around the 70's in the room, so I need to keep the light as cool as possible.

Get a timer that has 2 inputs and plug in the light and fan for that light into that timer, that is how I am doing it now

And look into a C02 tank when you get settled, you can find them cheap on craigslist

You can double your plants size and yield by using C02 vs without. - As per Ed Rosenthal

Like I said when you get settled

Good luck on your grow
