16/08: Put her in a container with a moist paper towel (with dechlorinated tap water) for 20h and she opened right up and grew a little tail.
17/08: planted her in a 15l fabric pot with light mix from biobizz.
19/08: she's alive!
20/08: put the lamp at 35cm dimmed to 25% which should make the PPFD of the most middle point 328 (if you read this and this is not good please tell me). I also watered her with some root juice and bio-heaven, she got 200ml.
