MareenGreen Incredibly good development after 11 days of vacation. The blueberry has doubled in size and all 3 plants have shown nice growth, pushing the flowers forward. I've added some more nutrients now.
@Pascal0815, hey, yeah those two were really thin at the beginning, after a week on the windowsill I started to gradually take them out after a week. Now they are definitely more stable, I also supported them with some wire. The next pictures will come on the weekend.
