Frithia seedlings

My Frithia didn't make it after all. Something in the care was wrong for it, pumice, water. I've gathered it's seeds from a seed capsule I bought it with and sown 10 of them as a test. Nine germinated and look fine so far. I hope they'll survive, even though I'm not sure how it'll go from here. I lack info on when the first true leaves are coming or when the substrate may be allowed to dry. Hope to figure it out in time.
Thanks for your comment
