I've paid for Nicholas the can on 06/06/2014 my girlfriend. We have also set up directly in accordance with the instruction manual. The box was a nice bright window seat (with us seems when the weather permits, the sun almost all day on it). We highlight the box every now and again, when it has become easier, she gets a few drops of water.
About 2 weeks later we discovered the first seedling.
Stand 01.09.2015: There are now 4, 4-5 cm high plantlets. They look like small dandelions, only instead of breath-seeds, arranged small soft needles in a circle. However, they grow very close to each other.
We'll see how that evolved, I try to keep you up to date;)
