I was looking around for a way to keep odors down in my small grow box and came across this little thing: http://www.surroundair.com/xj1000.htm Has anyone heard of using an air purifier/Ionizer as ordor control before. Im sure it wouldnt work for a larger grow but for a few plants, would something like this work for keeping odor down?? It says it's rated for 150 sq ft, so inside a 2'x2'x4' grow box it should work good if it would filter the correct stuff. And if it does $20 isn't a bad deal to solve the odor problem...
