Is your fan and filter inside the tent or outside?I have an odour issue here. I bought a new rhino pro filter at the start of this grow but still the house reeks of weed. The fan its matched with is slightly oversized I.e 4" filter with 5" fan but its married up right with no air escapes. Iv even changed my ducting. There is adequate air in to the tent and definite negative pressure in there but the house smells to high heaven. Have I bought a faulty filter? It's a year or so since my last grow and I cant ever remember my old filter leaving my house smell this way. I no it's best practice to filter externally but I dont have the option here so filtering into the bedroom is the only option. I'm at a loss really so will probably end up buying a new filter. For a gauge..... if someone who didnt no the smell walked into my house theyd assume an unusual smell. If a cop walked in I'd be fuked. And that's downstairs with the small grow upstairs.
