Tell your wife all your online friends have decided that you deserve a tent and said that she is lucky to have a such a talented guy. That should help you, after you tell her it's ordered.
Maybe don't stand in striking range and keep your house key on you, sometimes the color schemes of the tent drives them crazy.
Would it kill them to do some print patterns for modern living?
Seriously good grow going, and the wife will love the new purple/green tent. Call it "lavender" and "sage" for the bathroom
