C.walkeriana inside or outside?

[spes1959]

hi everybody: I am enriching my collection of walkeriana and two plants are now flowering. so far they are on the terrace with temperatures of 10 C as a minimum and 16/18 C as a maximum.

Do I leave them outside or do I take them to the glass-enclosed veranda facing south-west where the temperature ranges from 16 to 20C?

Thank you for your answers
