Cactus / miracle kabuto

Several Astrophytum asterias cv miracle kabutos were in flower.
This is one of them.
I collected seeds from my plants and sowed on 21/03/2006.
My main collection is asterias and I am trying to increase numbers of miracle kabuto.
I repotted 800 of 1 year old miracle kabutos lately.
I will sow a lot of seeds in November.
