Gym socks in my growbox.

Heh smells like some lightly soiled laundry in here. Over the last week my babies have aquired a slight smell (from about two inches nose shot) which of course makes me very happy though I know I smoked a LOT of skunk on my cross-country trip so one or both of these could very well be skunk which means i might have to hop to soon and make a carbon scrubber. Has anyone tried the DIY scrubber with the active charcoal filters? Did it work and if so how well.
