On Aug 28 the seed was put into peat pellet and in two days it germinated. On September 1 it was planted into the 0.5l pot.
Top Crop Coco coir was used. This substrate is needed to be rinsed before using. So I kept it in the clean water and after that in the solution of Top Coco A and Top Coco B (0.5ml nutrient for 1 liter of water)
