carbon filter help

I would probably go with a 435CFM 6inch fan and filter combo. What size fan are you using on that 4inch carbon filter? If the CFM for the fan is more than the CFM rating of the filter, that is why you would be smelling anything at the exhaust end.

Oh, also....is that cooltube reflector 6 or 8 inch? That would really dictate what size fan and filter i got...

thanks for reply.its a 4inch carbon filter /fan.and a 6 inch cooltube.i already had carbonfilter. temps were getting a little high on warm days.89/90.so bought cooltube was the smallest one i could get.

Nice looking plants Yea if the smell is leaking out still it would have to be the filter not scrubbing the air efficiently enough. How are your temperatures now that you have the cooltube/fan combo? If the temperatures are cool enough you could just replace the faulty air filter with a slightly bigger 4" one. But if your temp is still a bit on the high side, I would go with a 6" fan and filter combo. On a side note, do you have a hydrogemeter to check your humidity level? I have a cheapo one built in to my thermometer. If your humidity is on the high side a bigger fan would also help that probably.

i dont have a hydrogemeter m8 so i wouldnt really know, money is a bit tight.so haveing to get little bits at a time .and smell could become an issue were im growing so looks like carbon filter is now priority was looking at this one m8. http://www.hydroponics-hydroponics.c...action-kit.cfm

As stated, if your blowing through the filter with more CFM than the filter is rated for, the air is not in contact with the carbon long enough for it to absorb the smell, or the filter is getting old. Your tent should be sucking in a little, negative pressure. If it doesn't, the smell could be coming from a leak in the tent and you are noticing it at the exhaust because that is where your checking for smell. If the tent is bulging out, your filtering wrong and forcing air out of any leaks in the tent.Also check all your taped seals on your exhaust line. Tape does age and come loose. I have no experience with a tent, but that filter looks about right unless your growing some major stinky.
Some have the cooling for air cooled lights totally separate from the scrubber system. Outside air is pumped from the outside, through the light, and back out an exhaust. If everything is sealed, that air does not mix with the inside air in the tent. Then you have the scrubber and fan sucking through the filter and out its exhaust. That allows you to speed up or slow down the light cooling fan for temp. control without effecting the filtering of the tent. I know, another fan running and more noise...

Looks like a very solid carbon air filter. Gonna need a 6" fan for it to get the air moving....I personally can vouch for ValuLine 6" Centrifugal fan if you can find them online to order....I have two of em and they have been going strong for 2 years now. They are 435CFM which would be fine for that filter.

not trying to jack your thread but i need some help too if you dont mind. im growing in a 36 square foot space, i have a 190 cfm 4 inch fan/carbon filter, is that enough to remove the smell from my room? if not i need to upgrade now to prevent future complication when its too late. im also running it through a 400w air cool hood any help would be great/

Since it is just one 400watter you will probably be fine. But if you upgrade lights later or add any you will want to get something 400+CFM probably.
