Lobivia pentlandii cristata

Lobivia pentlandii cristata is one of my new cacti.
Therefore, I was interested to know how many days the flower lasts and whether it has a scent.
The flower lasts 3 days, closing at night and opening in the morning.
A flower without scent, although I persistently wanted to catch it.
Well, I really wanted it to have a scent! :-)))

In nature, Lobivia are found in Argentina, Bolivia, Peru.
The cactus is considered hardy, but it takes effort to bloom.
Lobivia is a very light-loving plant, but it is better to shade it from direct sunlight at lunchtime.
With a lack of lighting, its needles can crumble.
Watering is necessary only after the earthen coma is completely dry.
