After some weeks, there are new developments which I want to bring to you all here now.
Of the eight flasks, three had to go into Nirvana because there were contaminated with fungus. But five of the flasks are clean up to now.
Inside one of these five flasks, I believe to see tiniest dots of ... green? And not (yet?) more than a fraction of a mm big.
Please have a look by yourself, and tell me what you think. Could that be embryonic orchids?
