Byblis plantlets vanished?

[powersensor]

One month has passed since my byblis plantlets started vanishing. I managed to save only two plantlets. I realised that the byblis needed full direct sunlight in the open and on water tray with about 5mm high worth of water (by the way, my media is around 25mm thick). The water will dry up completely at the end of the day. Did watering daily.

It seems very wet media will cause the byblis to just rot away and vanished. Thanks Cindy for the advise.
