Hey Ambs,
Your tent is in your garage right? How much interest will potential viewers have in your garage? Buy a load of removal boxes and then when you have people coming to view (hopefully you will have - not sure what the market is like your end, but it's hard in most plaes to sell). Then just surround the tent with the boxes, (making sure to put away the ducting you have (you will only have 1 tent by this point right?) It's just going to look like you are packing things up so no one is going to be suspicious. Hell you can even leave the fan and filter running and just have a small radio playing in there. Remember you and Mr Trichome where in the stinky room for quite a few minutes before you even realised my grow was behind that door!!! It can be done I think....by the time you get the house on the market, potential viewers etc, it's going to be another week or so anyway....I think you should ride it out as long as possible (you are going to loose a fair bit of cash pulling that thing early.
Anyway, just a suggestion.
