Sempervivum, Hen & Chicks - now what?

Have managed to germinate some Hen & Chicks, but now what? I know nothing about Sempervivum. I've got a nice terracotta pot that used to house a saxifrage which croaked over winter. I'm intending to mix half compost and half vermiculite then transplant the seedling in little clumps into it.

Would this work? Or should I leave well alone until they're bigger? They've germinated in a small cold frame without any heat, but do they need to be moved to warmer conditions? Decisions, decisions....

 

Well done, I'd leave well alone for the time being, they don't need lots of space even when full grown, as you probably know.
Not grown Sempervivums from seed but quite a lot of succulents and they can be very slow in the early stages.

I'd slowly try to let the surface dry out a bit between waterings as there appears to be some green algae or moss starting to form.

Its a delicate balance in the early days between over watering and not watering enough.
watering from the base can be good, if possible.

I'd not give them any heat if they have germinated without any.

 

Thank you @pete, I feel more confident now. I've been 'blanket watering' a group of plant with a sprinkler on the can. I'll move it to one side to hopefully dry out a bit.

 

Hi @Jenny_Aster , looks good! I agree with Pete and would also suggest to do nothing, apart from watering a bit less. The seedlings don't mind being overcrowded and don't need pricking on. Once they are bigger and hopefully many more have germinated, you can re-plant them in clusters or separated where they are to grow.

Here is my batch, grown from cheap mixed seeds on windowsill in January. They are a jumble, but should be fine to pull apart when I plant them on. They are only now starting to show a bit of true colours after a week of hardening outside.

Lovely plants aren't they?

 

Thank you for your reply @Selleri, I can now see what I'm to aim for. This is a new interest, I know nothing of sempervivum. It's going to be interesting watching the seedlings grow. Thank you for all the pointers.
