Spikey

A few years ago I was very impressed by the football-sized cactus, many years old, that a friend had grown from seed.
So last year I bought a pack of mixed cactus seeds.
Out of the hundreds of seed just these 5 germinated, all apparently the same.
Think they may be due for repotting now as they are starting to joust with each other, and found this wonderful website when I was looking for advice British Cactus & Succulent Society
I feel the urge to get some more, different, seeds now!
