Blätter gucken aus Samen ohne Stamm?

The seedlings look absolutely fine to me - BUT they need to be in a pot with a lot more soil... that looks like an egg carton to me and if it is, transplant them NOW! Get them under good light that isn't too close (they will stretch to reach the light - if the light is too far away, their stems will be long and straggly and the nodes will be far apart... if the light is too close, there will be no significant growth and the nodes will be very close to each other). Good luck!

peat pellets? may have been too acidic. i'm not a fan of those because of how much water they retain, too. It's too wet for the seed at times. oxygen needs to penetrate. but, many make them work well. i'd soak in large volume of pH-balanced water to ensure they aren't too acidic. some seeds just won't germinate. usually due to age if they aren't hollow / malformed. I used jiffy pucks my first time and only had a 75% success. i don't do anthing special now and have near 100% success. Keep it simple, is my suggestion. Moisture and darkness is all a seed needs to properly germinate. The darkness is more for the tap root.. if roots are exposed to light they differentiate into stem, which would only confuse it early on. you'll know better in hindsight as you plant more... try new things.. 9-10 days is still possible.. better to leave them unmolested for 14 days to be certain they failed... probably rotting by that point. just keep them moist before it sprouts and that's all you can do. after that it's safer to let medium dry out a bit before re-irrigating... once it has a root.

Can someone please explain to me what the deal is with the matches? I mean seriously. I've seen it a lot but have no idea why people do that. 😏
