Tjoe thanks for sharing. In these situations I think we need to consider light , water and temperature because these issues are often interrelated . How is the temp difference created in the above situation ? Is it not possible that the hotter plant is seeing more sunlight and therefore UV ? We known that sun exposure has a dramatic effect on plants . In nature increasing temp is usually related to more sun exposure . A plant that sees more sun will use more water in its leaves . If you gave your hotter plant more water could it be possible that it would look more like the cooler plant but grow more ?
What do you think the two actual temps are for hot and cold in your situation
Not trying to be clever here or say that your statement is wrong . I just think we need to understand clearly what's happening because often more variables are at play than we think .This is why it is so hard for us all to agree exact methods of care for our plants apart from very general stuff like drain holes and as much light as possible indoors :

I do not dare to expose any fluffy leaves succulents to direct sunlight at my rooftop. Lactea, mammilarias, opuntias and some euphorbia with leaves will have like 30 mnts to 1 hour sunlight. It is too hot at noon time.
Just imagine that the haworthia at the hotter place is inside a garage, the garage expose to the sun the door and window is widely open, and the haworthia is 6 meter inside ( from the sunlight). This is the place that even at 5.30 pm in the afternoon is not convenient to sit down and have a cup of coffee.
While the other at cooler place, it is like on a patio next to fish pond, with a lot of trees around and the trees has blocked all the sun light, it is like 4 meters away from direct sunlight.

Both places are bright and good air circulation. Will try to measure the day/noon temperature, now at 6pm is 30 vs 27 degree celcius.70% humidity.
