carbon filter - must vent out??

do you have to vent a carbon scrubber outside of your room?

I want to set up another CGE (cosed growing environment) using a fan blowing air through the lights and an ac to control any other heat issues.

I also want to run a carbon filter. I would just use it on the exhaust from the lights, but the lights are going to have a closed ventilation system, taking fresh air form outside then dumping back to the outside.

Can I just set the carbon scrubber up in my room with both intake and exhaust being contained? Like a "scubber"?

I thought this was fine, but when I started looking at filters, I noticed some say "recirculating" and some do not.

Do I need to get a specific type of carbon filter to recirculate the air within my room?

Will this create any problems?

It is a 12x12 room and i want it ZERO smell. How big of a filter do I need? I like overkill... especially when it comes to preventing that smell.

thanks guys!

let me know when you figure out what works. i have NEVER seen anything get the smell to 0. i would say on a scale from 1-10 1 being 100% no smell, the best i have seen is about a 3(that is using a carbon filter and inline fan rated for 454cfm and the room is about 216 cf). then again, it depends on the strain.. some strains don't stink too bad.. others smell like you killed a family of skunks when you get a few feet from the house lol.

Yeah just leave it freestanding in the room, it will continusly scrub the smell.

get a vortex and a carbon filter i don't know the exact size but you know one of those like 4ft tall ones the BIG boys

thanks! Ive got a 850cfm centrifugal fan that I would like to push through the filter with in my room as a scrubber as long as someone experienced can confirm that this will work for my purposes.

with a sealed room, 850 cfm and a large carbon filter continuously scrubbing the air, it should be pretty low on the smell-o-meter especially being a sealed environment, im hoping.

Where to order one of those big boys? and which one is best?

will someone explain this whole scrubbing thing to me. I have a 1000watt HPS in a 4x8x7 tent with a carbon filter. Sorry for jacking you thread ill +rep you though

dont need to vent it out u can just use it to recirculate the air.. i use my carbon scrubber wit a 6 inch vortex fan.. it totally exchanges and expells the air in my room 2x a min .. also i use a passive air intake sytem good luck wit yours

how does it work for killing smell? I would use a passive intake also, but I want to run co2

baiscally scrubbing is just running the air in your tent through the carbon filter over and over again, "scrubbing it" without ever venting it out of the room

also, what is a good place to order an extra large filter from?

if u run co2 then u would not want to vent out or have passive intake.. co2 i believe requires a sealed room.. which brings up another problem of heat

this is how my room is set up


air comes in from vents----gets drawn across grow room taking hot air wit it--- through prefilter into carbon ----- up through fan --expelled out ducting into other area

this provides me wit a smell free environment as well as keeping my temps down

yea, I had to make a choice:

use passive intake with fan on lights to cool lights and vent carbon filter out and create vacuum to suck new air in through passive intake

or

go sealed and use co2 and use wall ac to cool room and use carbon filter to scrub only

Im gonna go sealed. How big of a filter and how many cfm would you recommend?

Im going to vent the light separately

thanks man!

depends on size of your room figure out the cubic feet first

it's going to be 12x12x10.5 = 1512cf

so with my 850 cfm fan it would scrub the air every 2 minutes. id this enough?

no u want to scrub the air at least once a minute

got it, thanks man!

no prob +rep is cool too

I am growing out of a fridge in my garage

My brother is my test subject, he does not smoke and it passed his test - no odor

I have a 165 cfm fan pulling the air through the filter

ok but how do you get the air from the carbon filter back into the fan? do I have to put it in a box? I made a picture so you guys could see if I have it right. because I would love to be able to seal my tent up (is that even possible?) and use co2. also does this lower the life of the filter?

u can seal up your tent as long as temp aint an issue

gotcha, so When you seal it you cant even have a window air conditioner pumping air in?
