Blooming cactus - Mediolobivia atrovirens

This is a 3 year old cactus grown from seed. I was so hyped about some older ones that decided to finally bloom, that I almost forgot about this little guy. And this little guy was already blooming last year at the age of two!

Mediolobivia atrovirens var. ritteri

Only one flower this year, just the same as last year. It last a few days only so it was a short lived joy. But I am glad. Don't think that I am not. I just cannot wait for it to grow bigger and show a nice bush of blooms!

This one is native to Bolivia and argentine and can be also found under a name Rebutia ritteri. A rather small cactus with very bright orange flowers.
I have only one like this so it better start growing some little offshoots, or fruits so I can sow another generation.

I was planning this year to actually get some cuttings from the cacti I like and make sure I have replacements. Last events just ensured me that I better do it fast. One day they are fine, 3 days later they are one.

And speaking of this one.
Do you guys (@nikv, @ludmila.kyriakou?) know why it has that yellow skin all over? I start to think that maybe I water them too little during the summer and they start to grow some kind of protective layer that prevents them from losing too much moisture. I am just a bit afraid to water too much when it is very hot in case they all cook.
Or is it a sign of some bugs?

The same thing happened on other types too. They grow this year normally, r at least trying. But this shell doesn't let them strech and they stay deformed.

Last year it looked like this:

Lastly just some Blurry artsy photos. Because I like them and I didn't want to just delete them. Now they gonna hang in the blockchain for eternityyyyyy....
