I have constructed a wonderful room in my basement, its sole purpose is to contain the smell of a**. Windows and the door frame were sealed and caulked. Ventilation shafts were plugged. Initially I would simply eat gassy foods and go to the room to fart. This worked on a small level, but not enough. I began defecating in a large plastic tub in the room and leaving it there to ripen. It is reaching near-toxic levels. I can’t stand in there now for more than a few seconds without a towel over my face. I invite you all to visit.
