Your girls are looking awesome. I run two filters in the room for the smell that's running all the time so when the door is closed you don't smell a thing. But if I take the plants out of the room for a short time you can smell them upstairs.lol I also get a blast of a strong smell when the lights go out which also shuts off the fans that cool the lights. Don't know why because the two filters are still running. After a short time you can't smell them anymore. I still have about five or six weeks to go to harvest so the smell will only increase.
