Cactus under carbonate 7

Hello everyone!
I suggest to viewing another portion of cacti.
Coryphantha in time.
I am grafting opponent, but everyone can see the charm of this cultivation method. Seedlings from one sowing.  I hope it is clear to all who will blossom earlier. About thorns, i am silent.
