If you knew how many people I've had stand right next to my tent, without knowing what it is, I think you'd be shocked. I've had people think it was anything from a portable wardrobe cabinet, to a portable darkroom, and only a few recognized it as a grow tent. To those who asked "Hey, is that a grow tent?" I've just answered with "Yeah, my wife loves to grow flowers year round.", just shrug it off like I have no interest in it, and that is the end of the conversation. The bottom line is it is none of anyone's business what you have in there...if they ask, tell them you are growing flowers. If they ask to see them, tell them you just treated them with something so you need to keep the door closed.
