Germinated the seed in a paper towel, until the tap root reached around 2cm.
Transferred it into a 17cm pot (around 4L) which I prefilled with Biobizz Light Mix soil, previously moistened with water and Plagron Power Roots.
When it has enough roots, I will transfer it into a 12,5L pot with Plagron Batmix soil.
A cup, with small vent holes, was put over it to keep the humidity high.
Lastly, I covered it with some net paper to prevent it from becoming to hot and drying out the soil/seed, since I put it in the grow box with my other plant.
Will update, when she sticks her head out ๐
Update: She stuck out her head just one day later and has stood up and became green in just 3,5 hours! ๐ฎ๐
