IKR?!They smell that good already it's a shame to filter the extraction air.
Wait on.. the smell is terpenes, and terpenes are what we want right? They are some of our best soldiers in the war against pain and sobriety.
Since we’re only filtering the air to be polite to the neighbours (ie. stealth) what we need is a way to get those terpenes back out of the filter media in a useful form. Know what I mean? Good, I’ll leave designing it up to you and check in how you’re getting on in.. what, you’re finished? Gizza look?
