Homes negative Ion with a Charcoal carbon scrubber.. I bought 2 of them... I put them outside of my grow room.. I grow in a garage.. in a closet in a garage.. So i just keep it outside my open closet.. Both of them.. And bam.. It smells like a Vaporizer of bud in my garage.. And believe me.. That stuff gets in your wood and the smell will not go away for a month... I attribute my safety to these things.. My first grow I had nothing... And you could smell my grow of 2 plants 30 feet away...
That's when I decided to do something... I didn't know any better that they would stink that bad.. Be warned.. Pot smells Extremely potent when flowering..
