I often encounter the term 'room temperature'. "This species of triops prefers room temperature", "that species of ant should be kept at room temperature" or "this plant does well at room temperature". At the current temperature of my room, however, the ants semi-hibernate and the triops are sluggish, stunted and prone to dying. At the moment, the temperature in my room is 18.8C (66F), and it stays within a degree or two of that temperature during winter. In the summer, when the sun shines through the big south-facing bay windows, it easily gets up to 35C (95F) in my room (and opening the window isn't that great an option due to the heavy traffic).
What's the temperature of your rooms?
