Sämling wächst er falsch?!?

and don't water so much 200ml on a 0.25L pot is quite a lot you're drowning the little one

The seed was planted incorrectly. The tip should always point upwards when it is buried in the substrate. In 90% of cases, the first root develops into a "U", pushing the seedling to the surface and ideally stripping off the shell. Your seedling is still alive, and I would keep an eye on it. Good luck!

Looks like it might of gotten too wet. Best is to dome them after planting till husk falls off. It will help keep area moisture and humidity. Plus warmer for germination to happen smoother.

this seed is def struggling to find some soft soil. You slightly overwatered in my opinion. Remember humid but not wet! roots like soft terrains Good luck 🍀

Dont restart if planting into soil place pinky finger into soil making divot then place seed in divot cover level,water like you would be taking a drink from water fountain then wait 2 days

I have had this problem. It's called helmet head. Essentially the seed shell is stuck to the sseedlin. Here's what to do: Drip a few drops of water onto the seed shell or mist some water onto it. Just get it a little moist. Then wait 15-30 minutes and do it again. Wait another 15 minutes. Then take a pair of tweezers and very gently try to remove the shell. It's possible the seed membrane will be stuck as well. The key is to get it moist so it softens up and then to remove it as gently as you can. If there is still resistance keep wetting it until it starts to loosen up. I've had this happen 3 times and everytime I have been able to successfully remove the shell and membrane and the seedling recovers just fine. Good luck!
