What I had not expected: The stuff moldy when it gets wet. All the pots put on almost immediately after insertion into the greenhouse mold - before irgeend germinate otherwise. Although the plants come at some point, but the mold proliferates properly. So I had not imagined it.
By the way can be excluded as the cause the earth. Because I have plastic and clay pots used and moldy because nix.
Therefore, it stays with me in this experiment. Immediately I pot up again to try or something else. Too bad.
Clearly: Can not recommend I.
