Cactus / asterias

I normally repot asterias seedlings in spring but I have tried it in autumn.
The photo is 1 year old super kabuto seedlings.
I repotted each of them into 50 mm square tubes yesterday.
If this trail worked well, I can divide repotting jobs into two, in autumn and in spring.
The repotting jobs of asterias are quite heavy because I have so many seedlings.
