I had to replant it into 15l pot, because the 0,5l was tooo small. Now it has a lot more room to grow roots and advance in growth. Next week I will start putting nutrions into the water and about id one to two weeks I will put it outside. Now the weather is too harsh for this small plant. Also I have noticed that the fisrt set of leaves is different. One half has 5 and second 4 leaf.
