I came home and found that my prized Drosophyllum seedling had withered while I was at work. I'm sure it had a reason but I don't what it is. I did nothing to it.
:-(
Did it dry out? Did you try reviving it with a little water? It is possible it did damp off but with such a loose well drained mix it is equally possible it got too dry. When they are small seedlings they can wilt very fast if that happens.
