Hello all,

I'm growing some cactus from seed. They popped up in early November
and are currently in a seed tray, in John Innes seed compost with a
layer of Vermiculite on top. The biggest one is probably not much over
half an inch high. I don't know when to repot them, or what to repot
them into - would they be ready for cactus compost yet?

All advice welcome...

TIA
Nick
