If you really feel it necessary to hide a grow tent in your garage (in a legal State). Make sure you never have a neighbor walk up on you, as your taking a rip off that bong, or right after you put out that J. People need to understand the, " I own this place" law. If you rent I get it. But a 30 year mortgage in a legal state, gives me the right. If I stop in at your house, only to ask why all the bottles are stacked up in your garage, and you say I'm making wine. I am not running around telling people OR thinking differently about you because of that. But if you need to hide it, then..... put some stickers like you see in any garage. ( Dewalt, Lowes, Home Depot, Craftsman). Set a few paint cans by the door, if you have a paint sprayer set it out. Then lie to them and tell them it's a small paint booth. Carry on.
