Holy crap cartman I did not know you could do that. Ive tossed them as well. Are you talking about the ona gel stuff or the solid chunk thing?


Carbon filters work good. If you have especially stinky ladies then a small odor can pass through and if its not checked then you can end up with a very obvious odor build up in a room over several hours.


I need to get a jar of ona for my grow area since the smell is starting to pass through the filter and building up.
