The stink of them varies so greatly that I can't give you an accurate stink-o-meter number

You might be able to get away without a carbon filter and just use a VaporTek 4000 like I've got. I don't think there's much here on the subject but I read a bunch over on icmag. including the endorsements of Rez (of Reservoir Seeds) and I decided I had to get one. I'm glad I did cuz I had a real stinky strain that I had to give away! Once I got the VT though I called up my buddy and demanded a cutting or two back. :smokin:

The vaportek is just a dry-vapor technology that makes your whole house smell like a hospital made of bubblegum (the actual gum, not the strain). The units are used in crime scene cleanup applications (lol?) so they work very well for our thing. I would Google vaportek 4000 and maybe even Google site:icmag.com vaportek 4000

More questions, just ask. It might take me a day or so to get back to you
