Lol, you wouldn't want to change the pressure as a keeper. I was trying to suggest that even when "nothing changes," there are external factors that you can't control. The temperature, light cycle, and humidity may remain constant year-round, but we can't do anything about pressure.

Unless you live in an old jumbo jet that has been turned into a house. If so, please share pics.
