Strain is K6 from what I was told. As far as the oder I have a carbon filter in the grow room that I have a fan that sits on top and doubles as a fan for the room and a tiger ozone in the outside room which has no plants in it. I did not use my carbon filter this time and don't have a oder problem persay. My room is so well insulated that I can contain the oder to my grow room space. Very little oder gets out and you have to walk up to my door to get a sniff and thats if you can get by the gaurd dog.
