I have a Secret Jardin 3x3x6' tent, 300 cfm extractor and CAN 33 filter. At night I set up a lawn chair in front of my tent, light a joint, then blow directly into the fan intake, through the filter. Five minutes after I zip her up and leave the room, you would never know I'd been there...zero smoke or grow smell.
Also forgot to say im going to be converting a wardrobe into my new grow palace just to make it unnoticable its going to look sweet and knowing i made it is going to be fun
