Hey guys got one of these http://www.mrgrowpro.net grow cases but the carbon filter that came with it doesn't do anything my house stinks. Can I just double up the filter material or is there a better solution
I think they are using microwave-filters or something like that (looks similair), so thats not really made for eliminating cannabis odor. Double up the filter will help a bit, but not much. Better make a DIY carbon filter.
