Are carbon filters really effective?

If hes pulling air thru the filter, that filtered air hits the ona before being exhausted.....I get what ur saying buddy, actually pretty clever as I was just going to put my ona at the end of the exhaust but i was thinking about putting it about a foot into the end of it. Props on your thinking pattern! BTW hes not scrubbing ona if hes exhausting, he is masking whatever got past the filter....just at the beginning, not at the end..

Aye i get it now i was stoned But yea second odor scrub is way to go and if i do start growing ill be putting in years of reading and thinking on it and ive came up with quite a few ideas.Just make sure you got a big ass extraction fan that sucks every last bit of air out of the tent and force it into another sealed area where you can either second scrub with say a wardrobe and ozone generator on every10mins of the hour or ona blocks.Just gotta remember to let air out of secondary scrub too or you could end up forcing it back thru the filter and some mad pressure might build up heh Personally i think i would do a dr100 tent with 125m carbon fiter exhausting into cheapest possible tent like dr60 and have an ona block inside that dr 90 and a 125m extraction too.Expensive though could use a wardrobe instead. If that filter is new and working i dont forsee how any smell apart from ona should be in the area apart from when you open up the tent.

You will also notice, since I just finished female seeds C'99, the Cindy is not that smelly during flowering. Now a strain like g-13 labs blueberry gum.. wow that is some smelly stuff that my phresh filter is doing a fantastic job of eliminating the odors. Yes, a filter is a definite must so you can keep what is yours private!!!!

. I got 2 g13. Blueberry gum vegging now. What did they smell like in flowering? My vanila kush smelt to high hell. I use a ozone and a carbon scrubber. The scrubber in the grow area and the ozone for out side area back up. I use a zonetec ozone generator. This thing can nuke my house in 1 hour.

A site veteran claims G13 Super Skunk is the smelliest nastiest weed he's ever grown. i am frankly curious now. cn
