Legal state? That right there makes all the difference. My buddy just bought a new place and said when they first looked at it there was a 10 x 10 in the garage with an active grow in it. He knew what it was but was fucking with the realtor and said "What, pray tell..is THAT?" He said the realtor just said " Looks like it might be a pot grow"....and went on....
A consideration you might think of....and something that happened to us when we sold a house a few years ago I'd grow in for 20 years....was that the "inspector" the sellers brought in notice 4 small peices of mylar behind 4 staples I missed in the area where I had my grow set up. He freaked....and from there....we went on a 12K escapade to rid the home of "mold".....cus...you know...IT WAS A GROW HOUSE... uhhummm. They found 2 small spots of black mold...IN THE ATTIC....not related to growing whatsoever....but it cost me....yes...it did.
So just the PRESENCE of the tent may set bells off.... I dunno if it's worth it for the small amount of weed you can produce....
but good luck with the sale however you proceed with things...
