How sandy/rocky should my drosophyllum media be

[Mufasa]

Right now i have some seedlings that are very small, germination started a few days ago, only i planted them in a very peaty mix and now i think that was a mistake

i want to seperate them out into a more rocky/sandy mix while they are still young to minimize the transplant shock
here's the mix i have prepared, but now looking at it, it still looks quite peaty

1 part scoria
1 part river sand
1 part of my usual cp mix (about 60-40 to 70-30 peat-perlite)

what do you guys think?

cheers.

so yeah... 0 replies... i ended up using about a 1:1:1:1 sand perlite peat scoria mixture... seems to be OK so far, they have continued growing.
