i found it, but the photos were gone and hard to follow like dude said... I talked to a friend who has grown before (never using carbon filters) and he said there is no way possible to keep this from my wife, she'll 100% for sure smell it when they're flowering...I've kinda mentioned growing to her a couple of times and got a very heavy "no"...so I would prefer to keep it from her if at all possible...You think it's possible or even probable...I really trust everything this guy told me, but like I said he's never had any experience with carbon filters...so I kind of want some other opinions.
