They look awesome, especially the big migiurtinus, it's looking very healthy and happy.

Sad to know about cubiformis. You lost it during winters? Also, what compost you are using, I mean what's the mix of your substrate?

No special mix. All my plants no matter what are grown in a commercial cactus mix. They are all thriving. I don't know what happened with the cubiformis. Both were treated exactly the same. It died long past the cold weather. The again, brown rot usually sets in a few months after the damage has occured. I thought the other would follow but it has kept on growing. fingers crossed with the 6 new babies.
